Convertible top works smoothly

Complementary Modification:

SmartTOP Override

The convertible top on the Porsche Carrera is hydraulically actuated. This means that rather than using the traditional approach of cable and pullies, the car uses a set of pressurized cylinders to both open and close the top. Over time, the system can leak or fail, causing your convertible top to get stuck in either the up or down position. In this article I will explain the basics of the system.

The basic operation of the system boils down to the use of two hydraulic actuators, mounted inside each rear interior panel. Each actuator is fed by the main system pump. If the system is low on fluid, it can operate loudly and cause the top to stop working. If you are having problems with your top, there is a chance you could just be low on hydraulic fluid. Sometimes simply adding fluid to the system can get it working again. Additionally, the fluid in the reservoir can go bad, especially if there are leaks or contaminants, causing the system to work harder.

Begin by moving the convertible top to the service position. This is where the front edge of the convertible top is about 12-15 inches from the top edge of the windshield. This is so you can keep the body flap open and also gain access to the pump. Once the top is in the service position, look under the rear window flap to find the guide cable connections. These are attached to the car with two ball joints (picture 1). The idea here is to keep the rear window flap down when the top is opening or closing. Pop both cables off the ball joints and fold the rear window flap up over the top.

Directly below, you'll see a carpeted area held in place with four plastic rivets. Pry the rivets out with a small screwdriver and carefully work the carpeting over the two large plastic blocks on either end. Once the carpet is clear of the blocks, pull the carpeting up and out of the car. You'll see the hydraulic pump for the system underneath. You'll also have access to the rear body flap motor as well as the DME computer and the relays. Locate the two hydraulic lines going out from the pump to the actuators. In between the lines on the pump, you'll see a hex plug. This is where you fill the system. Directly under the pump is the fluid reservoir. Shine a flashlight behind it to see the fluid level inside. The fill level line is right below the fill port plug. If you have determined that the fluid level is low, remove the hex plug and use a small syringe along with some plastic tubing to fill up the reservoir.

Another part of the system that can fail is the front latch mechanism on the center front of the convertible top. This motor assembly extends a hook out that latches the top against the windshield frame. If the motor inside fails, you can still manually open or close the latch. To access the latch assembly, pry the plastic cover off the latch mechanism from the front. Underneath you'll see the manual over-ride actuator and the mounting points for the latch mechanism. To open or close the latch, insert the 6mm hex key into the over-ride actuator and turn it counter-clockwise to close the latch (this is the same tool used to emergency open/close the entire top, located behind the rear seat panel) Turning it clockwise opens the latch. If you need to replace the entire latch mechanism, remove the four Torx bolts holding it to the convertible top and then remove the electrical connectors going to it. Installing the new latch mechanism is the reverse of removal.

If the convertible top cannot be opened using the switch, you can open it manually. This procedure is intended to be used only as a last resort as you can lose the reference points for the system to operate correctly, requiring the use of a Porsche factory computer to reset them. Begin by removing the rear panel behind the seats. This is held in place by two Philips head screws.

Once the panel is removed, you'll see the two access points for opening and closing the top as well as the tool stored on the bulkhead. For instructional purposes, we will assume the top needs to be closed. Begin by prying the circular covers off the roll bar bulkhead and insert the tool into the hex slot below. Now rotate the tool until both side flaps have been opened.

Now move back to inside the car. Locate the port on the right which turns the convertible body flap motor. Insert the tool and rotate it counter clockwise until the body flap is fully extended. Now insert the tool into the left side port and turn it counterclockwise one turn. This port is a pressure relief screw for the convertible top. Opening it allows you to grab the top and manually move it yourself. Grab the top in the middle and pull it up and over the car. Now use the manual over ride on the front latch mechanism to lock the top down.

Once the top has been extended into service position and the rear body flap is open,
Figure 1

Once the top has been extended into service position and the rear body flap is open, access the hydraulic pump by first prying the rear window guide cable ends off the ball joints on either side of the car (blue arrow)

Now fold the rear window flap up and over the convertible top to access the area directly below.
Figure 2

Now fold the rear window flap up and over the convertible top to access the area directly below. You can see end of the guide cables that have been disconnected here (blue arrow)

 Pry out the four black plastic tabs holding the upper part of the carpeting to the roll bar bulkhead (green arrows).
Figure 3

Pry out the four black plastic tabs holding the upper part of the carpeting to the roll bar bulkhead (green arrows).

Begin removing the carpeting by stretching the carpeting over the black plastic block on either side of the car.
Figure 4

Begin removing the carpeting by stretching the carpeting over the black plastic block on either side of the car. Once free of both blocks, lift the carpet out of the car.

Shown here is the hydraulic pump that powers the whole mechanism.
Figure 5

Shown here is the hydraulic pump that powers the whole mechanism. Over time, it may be necessary to add fluid to the reservoir below the pump (yellow arrow). To add fluid, remove the fill port plug (green arrow). Add hydraulic fluid until the level in the reservoir reaches the high mark which is located below the fill plug. Use a syringe with a long tube to both withdraw the old fluid from the reservoir and also add new fluid. Here you can also see the DME (blue arrow) and the DME relays (red arrow).

Shown here is one of the two hydraulic actuators used to both raise and lower the top (green arrow).
Figure 6

Shown here is one of the two hydraulic actuators used to both raise and lower the top (green arrow). They are located behind each rear side panel. The actuators are mechanically linked to the convertible top frame, so that when the actuators expand, the top raises. Here you can see parts of the convertible frame (blue arrows).

The front latch at the windshield can also fail over time.
Figure 7

The front latch at the windshield can also fail over time. However, you can also manually override the electric motor. Pull the cover off the front latch mechanism by pulling down on the plastic cover at the front (insert upper left, green arrow). Shown here is the front latch assembly with the cover removed. In thisPicture, you can see the manual override port (green arrow). Turning the 6mm screw inside counter-clockwise closes the latch, turning it clockwise opens the latch.

To remove the latching mechanism, remove the four Torx bolts holding the latch assembly to the front of the convertible top (green arrows).
Figure 8

To remove the latching mechanism, remove the four Torx bolts holding the latch assembly to the front of the convertible top (green arrows).

Once the front latch assembly has been removed from the top, squeeze the black tabs on both of the electrical connectors (green arrows) to disconnect them.
Figure 9

Once the front latch assembly has been removed from the top, squeeze the black tabs on both of the electrical connectors (green arrows) to disconnect them. Now you are ready to install the new latch assembly.

Access the manual over-ride for the top requires removal of the panel directly behind the upper rear seats.
Figure 10

Access the manual over-ride for the top requires removal of the panel directly behind the upper rear seats. Fold the rear seats down and remove the two Phillips head screws holding it in place. Now pull the panel out of the car.

Once the rear body flap has been removed, you'll have access to manually lower or raise the top.
Figure 11

Once the rear body flap has been removed, you'll have access to manually lower or raise the top. Shown here is the bleed valve used to actuate the convertible top frame (green arrow), the manual motor override for the rear body flap (yellow arrow) and the actuation tool stored on the bulkhead (purple arrow).

To manually open or close the top, you'll first need to use the tool to open the side flaps on the car (green arrow).
Figure 12

To manually open or close the top, you'll first need to use the tool to open the side flaps on the car (green arrow). Rotate the tool counter-clockwise until the side flap is fully open (yellow arrow).

You'll next need to open the body flap on the rear of the car.
Figure 13

You'll next need to open the body flap on the rear of the car. Insert the tool into the port on the right (green arrow) and turn the tool counter-clockwise until the body flap is fully extended. The left port on the car is simply a pressure relief valve for the convertible top pump (blue arrow). You'll need to open this port to allow the system pressure to bleed off. Turn the valve counter-clockwise one revolution. If the top is already closed, simply push it back until it folds back into the car by itself. If the top is already open, grab the top in the middle and pull it up and over until it is just nearly closed. Now use the front latch assembly over-ride port to close the top fully. Once closed, re-tighten the valve. Keep in mind that using this method of opening and closing the top may require you to reset the reference points in the system using a factory Porsche computer, such as a PS2.

duc Comments: hi Nick:

2001 convertible problem:

top is working fine before the battery is disconnected during IMS bearing replacement. Now the top is only working using the key from outside the car. Pushed rocker switch and nothing happened. Handbrake pulled up, handbrake light is on. What should I check. Since the top is working key why would the low fluid affect the rocker switch operation.

thanks, duc

Blue996 Comments: Do you have any details on the bleeding procedure when replacing the cylinders? I replaced both cylinders, filled the reservoir and cycled the top down then up once. On the way up, there was a loud air pressure relief sound and the right side had sprayed fluid all over the inside panel. Another reference has the following procedure and says to disconnect the cylinders from the top first? Won't the top lose its position if I operate it with the cylinders detached?


Bleeding the hydraulic system

CAUTION: Damage to the convertible-top frame it not running synchronously.

• Bleed the hydraulic system only after the hydraulic cylinders have been removed from the convertible-top sup- ports and drive levers on the left and right.

The system has a self-bleeding feature. Three to four operations will bleed the system. After bleeding, check the oil level in the container on the hydraulic pump and check if necessary.
July 15, 2016
  Followup from the Pelican Staff: The cylinders should auto bleed. Raise and lower the top the air will bleed. Top up as needed. - Nick at Pelican Parts

Didier Comments: Comment for Nike. Sounds like the micro switch at the roof closing latch. This triggers the "OK to close the rear windows". For example if you open the roof and press the micro switch with a small screwdriver you should be able to close the rear windows which is standard from the 997 onwards. Cheers

Charlie Comments: Hi,
I have a 1999 Porsche 911 Cab. I add fluid to the system about every 3 months. But this time, the motor is not working and I can't get the top into the maintenance position unless I do it manually. That said, the top is closed all the way; so if i manually crank it open, add fluid, then manually crank it shut, will it then be positioned correctly and I can avoid the computer reset?
Also, is there a level switch in the fluid holding tank that is keeping the motor from running when the fluid is too low?
Thank you for your help.
June 21, 2016
  Followup from the Pelican Staff: The pump may have failed from aerated fluid. You should be able to get it up and down without needing a reset. Just be sure if it in same position as before, don;t loosen nay top adjusting fasteners.- Nick at Pelican Parts

derinh Comments: Any suggestions on my 2005 997 C2S? Top opens/closes fine, but had a few random "top limit" errors last summer when closing. Now top does't fully seat in forward position when open see pic. Feels solid, but there is a 3/4" gap that shouldn't be there.
Do you think this is a hydraulic issue, or something else?
May 26, 2016
  Followup from the Pelican Staff: May be an issue with a position switch. it is a good idea to check the fluid level first. You'll want to check for faulty codes and check if the position switches are on and off when they should be. - Nick at Pelican Parts

tcc Comments: Had Indy look at it. It was something I've never heard of before and kind of lame. The popping sound was not a cable snapping, it was the rubber seal around the underside of the rear window mechanism snapping against the metal body as it was trying to close. So we're going to replace that piece of rubber. Roof operation is fine.

tcc Comments: 2001 cab. Without warning, a loud pop was heard near the end of the process as I was putting the top back up. The roof latch engaged and the windows are all up, but the clamshell is not fully closed. No error light comes on and when trying to re-open the roof, the front unlatches and windows go down but no roof movement. Perhaps a cable snapped?

Banff Comments: 1999 996 Checked fluid levels-full- Top will open and seat up fully. Then you press the button to close and you just hear the relay click. Had it all apart today. In a last ditch effort used the special allen wrench and turned it counterclockwise which released the "hatch cover". Just on a hunch I pressed the button and it closed properly. Opened it again and it closed properly. again just clicks and the "hatch cover" did not open. Did the same thing,allen wrench counter clockwise it closed and latched properly. A few times it has also been in the closed position and not worked. Assuming its the same issue with the "hatch cover" not lifting properly. Located two micro switches one by hydraulic motor and the other on the hydraulic arm driver side. E Brake light works, and tested the engine lid micro switch Suggestions for part replacement ? Sounds like a latch issue, but not sure what actuates that. For now at least I can get it to close in a pinch. Cheers you guys are awesome.
April 13, 2016
  Followup from the Pelican Staff: Check the cover latch. It may be releasing, but not opening enough to allow the top to open. This may be the position out of sync, causing the issue. You may need new hatch latches. Going by memory, i think there is a switch on the latch. - Nick at Pelican Parts  
craneboyj Comments: Hey Nick, i suppose the problem with the top has 'fixed' itself. Not sure if maybe there was air in the line or what. I had put some fluid in the reservior the day before so maybe that was the problem. Keeping fingers crossed. Thanks for all the help! ps One of the 2 smaller 'flaps' or 'wings' on the deck lid itself was not working properly. One of the levers had come out of its track.

craneboy Comments: Hi Nick, Thanks for responding...the issue i was having was trying to figure out what could be getting wet after i washed/rinsed the car. What electronics were in a precarious position near water drains etc...Now that i have taken everything out if the car, seats, all plastic trim pieces, and carpet, i found a metal tube, one on each side of the car attached to the wheel well. There were signs that there had been tubing on them at one point. I found small sections still attached. I guess it was to drain water to the resevior and out the drains located behind each wheel well cover. I have now fixed that problem. As far as all those failure warnings go they have all gone away. For now.'Fixed' themselves i suppose. The airbag warning is still flashing. Will have to get that reset. The problem im having now is the deck lid won't close all the way when im putting the top down. It stops 2 to 3 inches away from being fully closed. Also the top chatters and shakes as its going down. I've been around cranes some and when they are low on hydraulic fluid the cylinders would begin to vibrate and shake. Hydro oil reservior is full. Don't know when or if its ever been changed, added a little but still doing the same thing. Not sure if its hydraulic, electrical or if something got out of alignment. Maybe you have idea where 2 look. Thanks!

craneboy Comments: My car is going to the paint shop this week and i had removed the rear engine cover/spoiler assy. The top won't function if the engine lid is not closed. I 'fooled' it by pushing the catch mechanism on the lock to the lock position. The top works fine. I took the car to have the computer read and it showed 'no codes found'. I had removed the driver seat and the airbag failure light is on. However some of the other codes have not come on again.....but the problem is still not fixed. Will it malfunction again the next time i have to wash it?

My '98 C2 Cab roof opens and closes fine. However, the light still remains on when the roof is up or down. The car also beeps after locking indicating something isn't closed properly i.e. the roof!. What could be causing this issue? The only other thing that doesn't work as part of the open/close sequence is the windows won't return back up themselves. It does just seem like something isn't making contact to say the roof is properly closed. Any ideas?

Saratogapp Comments: Nick, I hope you may be able to assist with a problem on my 99 996 C2 cab where I can't get the clamshell / compartment lid to operate.

I can get the motor / gearbox to run OK, but it does not rotate the square drive, only the outer spline drive. I'm guessing that somewhere under the rheostat, something operates to engage the square drive with the splined ring, but this doesn't appear to happen. The spline rotates correctly, but the only way to rotate the square drive is with the Allen key supplied for emergency operation.

The cables that do the lifting of the clamshell are all free and easy and the electrical gearbox unit fits in and matches correctly. The mechanical cable lifting gadget has a square female drive that fits correctly but it has no matching spline.

So, my question is: should the square drive and the internal spline BOTH rotate....OR... is there a fitting on the cable lifting gadget that meets the spline, missing? I hope the attached pictures will help.

  Followup from the Pelican Staff: Good question, I do not know how the two work in conjunction. I would imagine, one turns, then once position is reached, the other does. Maybe at some point together. But I have never checked. i will look and see if I see anything in the function info that answers the questios. - Nick at Pelican Parts

Edgar Comments: I have a 2003 911 convertable. The locking mechinism closes and hooks and immediately releases and attempts to lock again, repeating itself over and over. I can stop the process as it locks and manually put up the windows but the top is not in place and the light indicating that remains on. Of course the rear windows will not go up. Thoughts.

Mezzo1161 Comments: Gents - quick question on the calibration procedure.
A year ago i have successfully opened the body flap with the screw as shown in pic 13 and got the actuators resealed. After installing them back into the car i reassembled the pump, filled it up but was not aware to reset the screw. The top worked for almost a year - only when it suddenly stopped closing the top lid last week. After a lot of fiddling i found out that the screw that opens the top lid needs to be set in a particular way to re-engage the motor with the top lid mechanism. I have successfully turned it back a couple of turns and re-calibrated the top.
Now, here are my 2 question: 1. What is the correct procedure to set the screw? After turning it all to the left, turn it x times to the right i guess but what is x? I have ordered some loctite as i saw that it was secured with that originally...
2. What is the procedure for the potentiometer setting on the lid motor? The value goes from 1kohm to 10kohms and i have set it somewhere to the end when the lid was completely open. Calibration worked but i read somewhere here that the setting was 6.2kohms...

Any help that someone can provide is much appreciated.
October 10, 2015
  Followup from the Pelican Staff: I had to guess at what year your vehicle is. Here is the calibration procedure:

Calibrating Convertible Top
Calibration of the Cabriolet convertible top and the convertible top compartment lid is carried out with the Porsche System Tester 2 diagnosis. The respective potentiometer values (convertible top and convertible top compartment lid) are established during calibration. If the potentiometer values are plausible, the values are stored.
The calibration values can then be calculated as a percentage by the convertible top control module from the potentiometer values. 1.8 - 2.0 kOhms

The following preconditions must be met in order to enable successful calibration.
The convertible-top latch must be repaired (after an emergency operation).
The convertible-top compartment lid drive must be repaired (after an emergency operation).
The valve screw of the hydraulic pump must be closed.

John Comments: I am working on a 911 convertible. I cannot get the rear quarter windows to go up. My main question is: What do I need to do to get the rear quarter windows to go up? I noticed there was a clip missing on one of the rods on the side of the rear metal cover and the rod was disconnected from the cover latch. I got a clip and clipped the rod back on and now the latch works. When the top is up and I push the down rear quarter window buttons, I can hear the motors clicking; but when I push the button to raise the rear quarter windows, I hear nothing. When the top is up, locked in place, the dash light for the roof goes out. When the top is fully down, the dash light stays on. How can I recalibrate the top without having the special tools? I really need to know how to get the quarter windows up. Is there a way to raise them? Where is the microswitch located that controls the windows? The front door windows work like they should. Thank you.

Crpavlik Comments: Following up on the convertible top troubleshooting. I have a 2003 996 C2 and my fluid reservoir is mounted horizontal to the left of the mechanism. Do I add fluid through the the hex screw on the end of the reservoir or through the hex on the mechanism as if the reservoir was vertical underneath? I tried the hex on the reservoir but can only fill the tank halfway. Top opens slowly then collapses when it's at the 3/4 point. Will attempt to close but needs to be assisted manually at the halfway point.

fishician Comments: Hi Nick, Thanks for the excellent post, I have a 2004 996 C4S with an intermittent opening problem. It appears to operate slowly and the motor whines when it gets half way open, it can still open all of the way and closes without problem. It appears as though something may be binding but I haven't figured out what it is yet. Closing is no problem. I haven't seen this described yet. Any thoughts? Thanks!

Hetherik Comments: I have a 2016 S Cab and am have top issues. Previously I had a potentiometer replaced and seems to solve them problem, bot only temporarily. The top labors to go in either indirection and lately has occasionally stopped completely and can't be trusted to go either direction. It's been suggested that I need to refurbish or replace the hydraulic actuators. I have never seen any leaked fluid on my garage floor or anywhere else, but I've been told it's low on fluid. What is your opinion in this issue and do you recommend refurbishing with same warranty as new to save a couple hundred bucks?

Johnny Hottub Comments: I have a 1999 996 911 and the convertible top latch goes into the lock position then comes back out again. I can stop it while it is inside the lock however I can not close the rear windows. someone told me that the plastic sleeve that covers the latch can be replaced to make the necessary contact to perform properly have you heard of this? and if yes; can I buy the plastic sleeve?
September 1, 2015
  Followup from the Pelican Staff: I haven't heard of this, but there may be an updated part. If you remove the current cover does is stay latched?

The only thing I noticed before putting the top down was loose, ripped fabric on the inside of the top behind the back window. Any chance the fabric got stuck in the frame when I put it down and is preventing top from going up?

Then I heard a quick beep of the horn, and now my lid will open but stop about 1" up. It looks like the passenger's side isn't raising, just the driver's. The fluid level is just below the cold line and it is cold. Any ideas?

TopDownAlways Comments: I have a 2000 996 Carrera with the type 1 latch it has three microswitches, hook continously cycles, seems to lock but then opens, tried pushing on the hook/lock, tried pushing up on the two prong plastic activator around the hook to see if the back windows close but they don't; open the latch and seems to be cycling fine, took it out and tested the three microswitches with and ohm meter all seem to open and close ok. I read on another forum the plastic cover around the hook when it cracks can cause a similar problem. Mine is worn and cracked but I don't see how this would make a difference in the latching since it does not touch anything in the mechanism and the microswitch is a separate actuator/part. Any suggestions?


June 30, 2015
  Followup from the Pelican Staff: The hook needs to press the center latch microswitch a specific distance. If the plastic cover is not intact the microswitch will not get the signal and the latch will keep trying to reach the switch. I would close the top and when the front latch makes contact with the microswitch use a pocket screwdriver to slide along the side of the hook and press up on the microswitch. If the hook stops replace the plastic cover first, and then if that does not make a difference replace the microswitch assembly. - Casey at Pelican Parts

  Followup from the Pelican Staff: Yes the Bentley Manual does have the emergency closing procedure. Go to pelicanparts.com and search for: PEL-P905 to find the manual.

Had my 2001 996 c2 parked up over the winter in the garage with the roof down. first time out today and tried to raise the roof but only the front windows whent down and the clam shell raised and the side flaps. then nothing. Any help would be appreciated
June 16, 2015
  Followup from the Pelican Staff: Sometimes things get sticky. I would repeat that a few times making sure the side flaps go all the way down and up. That should fix it. Once it opens all the way, repeat the process a few times to get everything used to moving again. I recommend doing this with the engine running. - Casey at Pelican Parts

Bignick Comments: On my '04 996 Turbo I attempted to close my top and the clam shell would only open an inch or so on the passenger side only. The driver side would stay down fully closed. Holding the dash switch in the close position long enough resulted in the windows closing and the dash light going off yet the top remained fully down. Is there a way to release or unlatch the driver side of the clam shell or how do I proceed? Thanks!
June 11, 2015
  Followup from the Pelican Staff: First try to help the clam shell up while an assistant presses the button. Chances are it just needs a little help. You can also try to reduce the amount of tension on the clamshell by pressing down as soon as the button is pressed, then letting it open. See if those tricks work. Let me know how it goes. - Casey at Pelican Parts  
Joe Comments: I have 99 cab. The top goes up and down fine mechanically. However, when the top goes down, the canvas does not fold correctly and rests on the metal latch before the clamshell closes. If I don't manually tuck the canvas in, the latch punctures the canvas top hen the clamshell closes. It has torn several holes dead center in my roof. Any idea what is causing this?

June 2, 2015

James Comments: I have a 2006 Cab and the top has been up for the past year. Now when I put it down there is no problems but when I put it up the latch goes up and down on the window shield. I can stop it with the bottom but the windows do not go up automatically. What could be the problems?
June 2, 2015
  Followup from the Pelican Staff: Could be a faulty microswitch in the roof frame or that the latch is not pushing in far enough. If you push up on the latch catch while holding the button do the windows roll up?? If so the microswitch assembly is likely faulty. Could also be the latch but the microswitch is more likely the culprit. - Casey at Pelican Parts

would durametric put roof into service position???

June 1, 2015
  Followup from the Pelican Staff: Double check to make sure the parking brake signal is getting through. Does the Park Brake light on the dash light up when you lift the handbrake? You can usually get the top in service position with the button. - Casey at Pelican Parts  
Lee Comments: Don't think my problem is mention in the myriad of concerns other owners are having: I have a 2001 Carrera Cabriolet that has been catching the canvas on the cowling latch mechanism when I puttee top down and the cowling does not finish the final seating movement. I have checked the top pension and it seems OK but not sure parameters. What causes the canvas to fold wide enough towards aft to catch the cowling latch?
May 29, 2015
  Followup from the Pelican Staff: I would bet that one of the tension straps is broken in the canvas top assembly. - Casey at Pelican Parts  
T B Comments: I have almost fixed my 996 top, but I am still having difficulties calibrating.

Using the Durametric tool, it would calibrate fully and appear to work, but it would log a potentiometer fail. Then the top would work intermittently but stall occasionally and require a short wait or a slight push.

I removed the potentiometer on the motor and the inner plastic gear fell apart in my hands. the black one that goes on the square shaft and has outer teeth, not the orange one that is part of the pot.

I did my best to glue the whole mess together and assembled it. I set the pot to 6.2K as prescribed, but I am not sure if I had the clamshell and top in the correct position for this setting. The top was slightly open but the clamshell was fully DOWN as I couldn't raise it with the bolt loose.

It worked again, and calibrated again, but still shows pot failure.

Questions:

- Where should the clamshell and the top be when the pot is set to 6.2K? Did I mess that up?
- Is the inner gear available? Or is it included with the pot and it is available? Are any parts available other than purchasing a whole new assembly with motor?
- Any advice?

I started a new post because I realize I had multiple issues
May 26, 2015
  Followup from the Pelican Staff: I am sorry but I do not understand the 6.2K, where did you get that spec?? Is that in an effort to avoid calibration?

It does appear that the potentiometer is available separately. OEM-99661331302

Tierraman Comments: 1989 911 Cab, Top works fine; Top warning light goes off when top is down but doesn't go out when top is up. Front motors latch all the way. If I disconnect the control module and reconnect, warning light goes out, but if I open and close the front latch motors, light comes back on. I've pulled the control module to view the condition of the solder points. Is this the right direction? Everything else seems to work fine, other than the notorious warning light issue...
May 11, 2015
  Followup from the Pelican Staff: Disconnecting the module will always turn the light out because the inputs and power to the light are cut off, BUT those control units are notoriously faulty so I think you're going in the right direction. Another issue I have seen is when the wiring which runs along the roof breaks cutting the microswitch inputs to the control unit and making the light stay on. I'd say check both of those two things, and you will probably find your answer. Also don't forget the power of a thorough visual inspection. Looking at things pay close attention to things that don't look right. We all have a little mechanical intuition especially on the vehicles we drive often. Let us know how it goes. - Casey at Pelican Parts

i have lived with my 1998 996 c2 roof not working for a yr and a half.
in all the time searching for help i have never found a page as helpful as this one. WELL DONE AND THANKS.

I took car to local INDEPENDANT PORSCHE garage who did tests they topped up fluid, replaced rear latch mechanism, swapped roof control module with another and durametric tested all sensors which all seemed ok.

some times it would work then when putting roof up would freeze around the service position about 8 inches from window screen. if car is left a couple of hrs it would work and close. which made me too scared to use it.
ive spent a lot of money and roof still dont work, it is stuck closed, nothing moves at all now.

can you help??? can you even do the works required. its depressing me as car is worthless in currant state !!!

hi thanks for the reply.
as for symptoms, when the roof stopped 8 inches from window screen the hook was out i think.

the motor does not sound noisy at all.

there was one thing, the last time it worked whilst putting the roof down the front latch mechanism made a loud bang as if it was stuck in the wind screen. i took it off and had a look but nothing jumped out to me as if it was broke.

cheers.
May 11, 2015
  Followup from the Pelican Staff: Ahhhhh very good information! Chances are something is bent, or has gotten out of calibration due to the front latch hanging up. Check all the arms fasteners make sure they are tight. I have found some cars that the pivots for the arms in the rear get loose and the top doesn't work right. I bet you'll find something loose or a fastener missing. - Casey at Pelican Parts

  Followup from the Pelican Staff: Sorry to hear that...This can be hard to diagnose without seeing the car in action. When the top stops 8 inches from the windshield frame, does the top function in the down direction? Or does it just stop all together? When it stops does it sound like the pump is straining? Since all the electronics have been checked by the shop I would start to check fasteners for tightness and check the very basic things. Can you help the top past the point where it stops gently with your hand? - Casey at Pelican Parts  
T B Comments: 2001 996C4 here.

The top failed last autumn with a cracked plastic gear in the flap mechanism. It skipped a few teeth and the top froze.

This spring we replaced the mechanism and calibrated the top with the scanner, and everything works, top goes up and down again.

However, when the top goes down, everything looks correct and snug, but the dash light still shows the top "opening".

Is there a final microswitch that tells the car when the top is fully down? Or am I back to calibration hell again?

Thanks.

S33SSG Comments: Hi, I have a 996 Gen2 C4 Cab 2202. My hood was working fine it then suddenly stopped halfway through being put up. I had to use the manual override to get it closed but now the rear side windows will not come up at all they were fine before, front side windows are fine. The roof has latched closed correctly, there is no warning light on the dash, the parking brake light comes on when the brake is applied, there is no warning that the engine lid is open and the battery seems fully charged. The hood no longer works but in doing the manual override I have changed the pressure settings on the pump. The electric bits work IE the latch etc. its just the hydraulic bit of the hood that doesn't move but the rear clamshell does move!!! My questions are:
1. What is the correct setting for the hydraulic pump the gold Allen key on the front that is adjusted by the long red Allen key? I am sure I have completely ruined any setting it did have when I did the override
2. How can I get my windows up and why are they not working?
Thanks so much for any help
April 14, 2015
  Followup from the Pelican Staff: Ok answer to number 1 is completely screwed in. That emergency plug only releases pressure held by the pump so that the top can be moved freely. Screw it back in and the top should activate.
Answer to number 2 could be related to the top being uncalibrated. Try to address number one first, when closing the top hold the close button until the top closes, AND the windows roll up. This helps teach the control unit by going through the whole process. - Casey at Pelican Parts

Kparmstrong Comments: My cover seems to work fine, the top goes up and down fine, windows work fine. When it gets to the part for the side flaps to go up or down, it takes forever.

tripp Comments: I have an '06 C4S Cabrio, and I am noticing a creaking/shifting noise when the top is up and I drive over a speed bump at an angle or into a driveway where there is any twist on the body. It almost sounds as if the convertible top shifts a bit, and this is the sound of an otherwise tight part creaking or shifting when I say 'creaking' I dont mean a squeak, just to be clear. Have you any experience with this? I could see a solution as either better lubricant in joints, or perhaps even a better sealant like replacing the rubber strip where the top meets the windshield. Thoughts?

I have a 2011 911 Turbo S Cab and have some issues with my top. There is wind noise coming from the rear passenger side corner and after i washed my car today i notices that in both corners of the convertible compartment there is water, which also leaked to rear seats. Do I need to replace seals that on both rear of the top and on the lid compartment or is it something else.
November 10, 2014
  Followup from the Pelican Staff: Inspect the seal, they do leak. The wind noise is a good indication that something is going on back there. Check the top seal, that is the most likely culprit. - Nick at Pelican Parts  
golfdude Comments: Good Info! 1999 Porsche Carrera Cabrio. The problem-top worked fine until last week. When I push the OPEN button-windows roll down, top unlatches, but no movement. Brake light ok. Fluid level good. When I open compartment lid manually, the top will cycle close-then won't open. Top will also cycle open but OPEN light stays on when compartment lid is down. I tried pushing down on lid to no avail. How many microswitches are there in the compartment area or should I look at something else. Lastly, when trying to lock compartment lid manually, the nut where allen wrench goes in; breaks loose and there is no "lock" sound or feeling. Only had car a few months and car was neglected by previous owner. Any help is appreciated. Retired Vet-TX

  Followup from the Pelican Staff: Check your owner's manual for emergency operation. Once you detach the top from the mechanism, look for damaged cables or rods. It is possible the latches are not releasing. - Nick at Pelican Parts  
Mikensite Comments: 2004 C4S Cab - top opens and closes properly, but when closed, the "Top Open" light on the dash is still on and the rear windows do not operate. Are there any switch on the windshield frame or they are all on the back assembly?
Also the top is curling inwards about 1/4 inch, the grip holding the canvas is gone or loose. Don't know if related.
October 18, 2014
  Followup from the Pelican Staff: There are switches in the latches at the windsheild. This may be your issue. - Nick at Pelican Parts  
Franz Comments: I have a 2005 Carrera S Cabrio. The cover on the locking device the portion attached to the front portion of convertible top came off. It does not appear to be damaged, and the top still goes up and down, locking and releasing properly and smoothly. However while it looks like the cover should simply snap back on, I cannot get it to do so. I have perhaps not applied enough pressure as I am not sure that is how it really attaches.

Any thoughts and advice would be appreciated. Many thanks.

Ray_S Comments: I filled up my horizontal reservoir today 2004 turbo Cab but still have some issues opening and closing the roof.

Is there a procedure I need to follow to bleed the system?

Issue is - there seems to be a "dead spot" - once opening, the roof crashes down on the last couple of inches. Upon closing, there is a an unusual delay after the lid openend, takes couple of seconds before roof starts to close then.
Is it possible I need to bleed somehow?
October 5, 2014
  Followup from the Pelican Staff: The system should self-bleed after a few operations. Is the fluid foamy? - Nick at Pelican Parts  
John Comments: My 2007 997 Cab top wont latch at the top latching hook. Also, smells like an electrical burn at the top latching motor/mechanism. I closed it manually, but now what? Replace the whole mechanism or just a motor within the top latching unit? John

  Followup from the Pelican Staff: I would think it is just the motor. I would remove the motor and see if the latches locks and releases properly, if so just replace the motor. - Nick at Pelican Parts

PorscheC4S Comments: 2004 C4S 911 996 Cabriolet convertible failure.

The hydraulic system works well with opening and closing but only if the rear crescent deck cover is first manually opened. It will not open or close on its own though the motor that is connected to the Allen makes a sound when pressing the convertible top button. The rear shell does not latch at the far back. It seems there is a failure of the deck cover function that prevents the hydraulic system for the actual convertible top to delay and therefore not engage and work.

Please advise
August 15, 2014
  Followup from the Pelican Staff: I would think the issue is with the drive for the lid. I am going by memory, but I think the cables are problematic. - Nick at Pelican Parts  
Sam Comments: Hi Nick, when I press the button to open the top 2004 996 turbo cab it opens the latch but then isn't able to open the top any further. I checked the hydraulic fluid which was low so I filled it but it still won't raise or close the top. Based on your comments above this seems like one or both of my actuators are faulty. Would you agree with this conclusion?
August 4, 2014
  Followup from the Pelican Staff: Before guessing at the actuators, check if the latch switches are working. If the control module doesn't see the latch open, the top will stall. - Nick at Pelican Parts  
bbirt Comments: I have a 911 996 that the top will not open. I did find the oil low and filled but I just hear two clicks. Fuse is good and emergency brakes lights on the dash. Once pressing the open button the flashing top icon is displayed on the dash. Should I hear the motor. Or what can I trblshoot further. I have manually lowered it and then tried to raise it, but no go. Also the top lock did open but nothing more.

Is the a solenoid valve which changes flow direction or is the motor reversible. Any help would be appreciated

Ash Comments: Hi Nick,

Its a 2010 Carrera 4S. I think you are right - it isnt moving at all - as though the latch is locked on and wont release. Any advice on how i can get it to release?

Help is very much appreciated.
May 22, 2014
  Followup from the Pelican Staff: If you can get to the cable, I would pull on it, but be careful not to detach it from the far latch. Maybe follow it to the solenoid and activate it from there. If the latch itself is jammed, you may have to pull up on lid while you release it. - Nick at Pelican Parts  
Ash Comments: Hi Nick,

Great article - like everyone else i too am having convertible top malfunctions! My problem though is the deck cover which needs to lift before the hood can retract seems to be stuck on firmly on the drivers side UK car - the other side actuates perfectly - but I dare not take it any further in case it warps the deck cover. Its like its latched on permanently. I cant work out though how to manually release it so I can get to the pump to check the fluids - any ideas?

Is that something I can order. Not sure what to do from here please see picture

Dave Comments: Hi, great website and great article. My problem is with the top fully closed, when I press the button to lower the top, the windows go down all the way, but then the top doesn't move and there are no sounds brake light shows on dash, and I assume since the windows lower, the brake microswitch is not the problem. Durametric tool shows fault code 5 time out. Is this likely the latch microswitch? Also, I don't recall, are the windows to go all the way down, or only half way before the roof moves? Thxs!!
April 14, 2014

Mike996 Comments: Hey Nick:
I have the same issue where the top keeps trying to lock into the windshield
I have seen other postings that indicate it could be the plastic covering on the latch, as mine is broken I'm thinking this could be the issue.

Could you tell me how to replace this?
I will order the part immediately if I can find out how to replace it.

April 5, 2014
  Followup from the Pelican Staff: No really. Just keep it clean and monitor the fluid level. - Nick at Pelican Parts  
Karl Comments: Hi Nick. Just purchased a 2003 911 Cabriolet. The top operates fine, but it has some creaking when I drive with the top up. Do the joints or pivot points need lubrication? And what else should I be servicing to ensure long lasting reliability for the top operation. Thanks

Stefano Comments: Hi Nick,
I have the same symptoms of user Ransom below Jan 24 and Feb 02:
during the opening phase of the roof, when the roof is already fully folded, the shell cover hesitates to fully close. If takes few times going up and down before it actually completes the process. And during the top down the shell even seems to shiver...
I checked the fluid level and discovered that I have the horizontal fluid reservoire.
My fluid fills half of the fluid plastic bottle and the level crosses exactly the ' + ' sign showed in the attached photo.
1 what is the correct level of the fluid for the horizontal fluid reservoire? Full or half full?
2 you suggested to Ransom that it could be the alignment issue. What is is? How can it be solved? Is there a guide?

Thanks a lot.

AJ Comments: Hi! - thank you for all the info on this topic! - My 2001 carrera top is working fine and quiet WHEN I can get it started!! I seems to get stuck in the open position and when pushing the button to close NOTHING - only a soft click, click, click form the back - some microswitch fault? where/how? I followed your advice yesterday published in previous articles: filled the hydraulic pump to correct level was very low! and also added some grease on the hooks/latch
February 16, 2014
  Followup from the Pelican Staff: Is the parking brake light on and is it engaged when you try to open the top? The clicks might be the latches releasing, then it stalls due to not seeing a switch position. Try to help it up, does it open with a little guidance?- Nick at Pelican Parts  
Ransom Comments: Nick - thanks. Anyway to tell? or fix the alignment issue?
Is is an alignment with the rag top or shell most likely?

I see the shell hesitate and go half way down and back up several times before fully engaging and closing.
February 2, 2014
  Followup from the Pelican Staff: Hard to say, but I would think the top has the alignment issue. You can take some measurements as the top opens and see if anything seems bent or skewed. - Nick at Pelican Parts  
Ransom Comments: I have a 997 - '06 - and the top works great - but the shell cover will not always close all the way during top down - it takes several tries before it fully closes and indicates that the top is open. IT seems that the shell is pushing down on the folded top when it does this. Is this a sensor issue? an electric motor issue? or a position setting issue with the shell?
January 23, 2014
  Followup from the Pelican Staff: Sounds like an alignment issue. Especially if the top is trying. If it were a sensor, the top may stop or set a fault. - Nick at Pelican Parts

  Followup from the Pelican Staff: If the motor is attempting to work but lacks power or force. The motor could be faulty, or there could be a part jamming the motor. I would check that the motor is getting power when you attempt to open it. If it is getting good power and the motor is not working it could be faulty.- Nick at Pelican Parts

Hurdigurdiman Comments: Jacolas Take the top into service mode and you will see where the clam shell latches into the H style bracket under the clam shell. You also see the hook sticking up which goes into that final pull down on the clam shell closing it completely. Put a good dab of O ring grease or similar onto each part ie:- The hook and the H bracket. Try it again. I had the same problem and this action solved it. The hook was not going completely into the bracket because both were very dry and binding on each other. Good luck.

It went half way up and stopped. after further investigation I suspected mice in the lining few holes couple of seeds on the floor. I sort of traced their route and eventually found a nest behind the back seat in amongst all the hydraulic stuff. So far I have discovered they have chewed through one of the hydraulic hoses, which explains why the roof went half way up.I have read your article on filling up the fluid but could do with some advice on reparing or replacing the hose. I couldnt believe it. cheers JOLLY Liverpool UK
September 12, 2013
  Followup from the Pelican Staff: Here is what I remember about replacing the lines:

1. Place top in top-up/locked position and activate the top-down operation just enough to unlock the front top latch and retract the rear deck.

2. Remove the key so that the top cannot be accidentally activated during the procedure.

3. Reach under the deck, remove the rear top anchoring cable ends by levering them off with a prying tool. There is one on each side.

3. Lift up the back edge of the top and push it forward. The top should stay in this position without support.
Note: From 2002, cars with rear glass window, the back edge of the top will need to be supported to stay open.

4. Remove the rear deck carpeting

5. Remove the retaining clips from the hydraulic cylinder drive pin and frame pin. Remove the left and right drive arm. Remove the drive arm off the pins.

6. Gently pull up on the hydraulic lines to remove them from the mounting brackets. be careful not to bend the lines.

7. Unbolt the banjo bolts for the lines and remove them. Note the positon of the sealing washers and any electrical connectors.

  Followup from the Pelican Staff: Without knowing where the leak is coming form, I cannot tell you what to fix. If you pinpoit the leak and describe the area I could be more help. Try jcking the vehicle and looking for the source of the leak. Look for dripping or a clean oil soaked area. - Nick at Pelican Parts  
Jack Comments: Reference above ie clouding flap , I had the sme problem. I solved it by taking off the potentiometer on top offlap motor drive and adjusting.
There is a resistance measurement if between 6.4 and 7.2 ohms fir setting but the cruder way is to lift off potentiometer and rotate by one segment at a time. Trial and error system but I got there and mine works great now .
Hope this helps. Jack Brown, UK.

After replacing the right rear window regulator we were "excersizing" the top to make sure all was OK and on the third time when the right side cable the pushes and pulls the lid down.. broke.. $700 later and a trip to the shop that has a PST2 to recalibrate got the top operating...Customer, of course, wanted to know "Who broke it"... Had to supply the normal response... "It broke itself" not very satisfying to the customer but still the truth... now the car's back again for slow operation and stopping... Probably low on fluid.. a leak somewhere...
