Parts Required:

Battery, battery vent hose

Hot Tip:

Wear eye and hand protection.

Performance Gain:

Car will start well.

Complementary Modification:

Replace battery vent hose
When replacing your battery, be sure to use a high quality unit. Replacing the battery can be done in a short amount of time.
The battery in BMW E90 models is located in the right side of trunk, behind a trim panel.
Figure 1

The battery in BMW E90 models is located in the right side of trunk, behind a trim panel. Read battery connection notes before disconnecting battery. Before disconnecting your battery, remove key from vehicle and store in a safe place and note radio presets. When battery is reconnected or loses its charge, the following items may need attention (depending on vehicle equipment). You may have to reset your clock, enter radio presets, initialize power windows, initialize the sunroof and normalize the steering angle sensor. Once your battery has been replaced, you will have to register the new battery with the vehicle computer system. This tells the DME the age and health of battery to ensure proper charging.

Charging battery:
You can connect a battery charger directly to the battery or under the hood at the positive (+) and negative (-) grounding point junction.
Figure 2

You can connect a battery charger directly to the battery or under the hood at the positive (+) and negative (-) grounding point junction. The battery junctions are located at right front strut tower, green arrow points to positive, yellow points to negative. However, I suggest removing battery from vehicle when charging. This will avoid filling your trunk with gas that the battery emits during charging. Follow the manufacturer's instructions on setting and using the battery charger. Jump Starting vehicle: A vehicle with a discharged battery can be jump started using a good battery or a good battery in another vehicle. When jump starting: Be sure to work in a well ventilated area, batteries can produce an explosive gas. Wear gloves and eye protection and if battery acid comes in contact with your skin, immediately flush with water and seek medical assistance. Move both vehicles close together but do not allow then to touch. Turn ignition OFF in both vehicles.

Connect one end of positive jumper cable to positive (+) battery terminal of vehicle with good battery.
Figure 3

Connect one end of positive jumper cable to positive (+) battery terminal of vehicle with good battery. Connect other end of positive jumper cable to positive (+) junction terminal (green arrow) vehicle with discharged battery. You will have to flip open lid on positive (+) junction connection. Connect one end of negative (-) cable to negative (-) battery terminal of vehicle with good battery. Connect other end of negative (-) jumper cable to negative (-) junction terminal (yellow arrow) of vehicle with discharged battery. Start engine on vehicle with a good battery. Allow to idle, then raise engine to 2000 RPM. Next, start engine of vehicle with discharged battery. Once vehicle with discharged vehicle starts, shut OFF any electrical accessories, radio, HVAC blower, etc. Carefully disconnect jumper cable in the reverse order you connected them in. Allow vehicle with dead battery to idle to recharge the battery.

Replacing battery:
Working in trunk, twist trim panel lock counterclockwise then open and remove trim piece.
Figure 4

Working in trunk, twist trim panel lock counterclockwise then open and remove trim piece. (green arrow)

Using a ratchet and a 10mm socket, disconnect negative (-) battery cable.
Figure 5

Using a ratchet and a 10mm socket, disconnect negative (-) battery cable. (green arrow) Move negative (-) cable aside and cover so it does not accidentally come in contact with battery terminal.

Release locking clips and open battery safety terminal cover.
Figure 6

Release locking clips and open battery safety terminal cover. (green arrow) Photo shows lid open. There are two plastic locks on each side of lid you have to release.

Release locking clip and open battery power module cover.
Figure 7

Release locking clip and open battery power module cover. (green arrow) Photo shows lid open. There is a black locking tab you have to release. Press tab toward front of vehicle and open cover.

Then using a ratchet and a 13mm socket, remove battery power module nut.
Figure 8

Then using a ratchet and a 13mm socket, remove battery power module nut. (green arrow)

Then using a ratchet and a 10mm socket, loosen positive (+) battery cable.
Figure 9

Then using a ratchet and a 10mm socket, loosen positive (+) battery cable. (green arrow)

Lift battery power module up and remove from battery.
Figure 10

Lift battery power module up and remove from battery. You will have to detach clips at side that lock onto battery. Lift positive (+) battery cable off battery and lay aside.

Using a 10mm socket, loosen and remove battery hold down.
Figure 11

Using a 10mm socket, loosen and remove battery hold down. (green arrow) Then disconnect battery vent hose. Lift battery up and remove from trunk. Be careful and make sure you have a good grip, the battery is quite heavy. You will have to move cables around and keep them out of the way as you remove battery from vehicle. Clean battery compartment thoroughly. Clean corrosion from battery cable ends if present. Before installing new battery, check that battery vent line is not pinched, in good condition and properly routed. Replace if needed. Install battery in compartment, attach vent line. Connect positive (+) cable. Next connect negative (-) cable. Install battery hold down bracket. Then reassemble trim cover and trunk carpet. Once installed, you will have to use a BMW scan tool to register the battery. This can be done by a capable BMW shop, I recommend doing it immediately after replacing your battery.

A-Bomba Comments: Hello Ive been having to reset the time on the car for 2 weeks and getting the Increase battery discharge message. I googled the issue and everyone said change the battery. I changed the battery today with an aftermarket battery and Im having the same problem. My Rear defrost wasn't working and started working once I changed the battery. Weird ? please help thanks
November 23, 2016
  Followup from the Pelican Staff: You could have a battery draw. The vehicle should be checked for fault codes and have an energy diagnosis performed. - Nick at Pelican Parts  
Oliver C. Comments: I had my battery taken out to replace bst and once it was put back my mirrors wont adjust, everything else has power but not my mirrors? 2008 bmw 328i
November 22, 2016
  Followup from the Pelican Staff: Possible a fuse was blown. I would start by checking the fuses. Then monitor the mirror switch input using a BMW scan tool. - Nick at Pelican Parts  
Randall Comments: Replaced my battery today. No windows, interior lights, signal lights, mirror adjust, signal lights, or fog lights. ??? Car starts and runs fine, central locking is ok, radio, clock, display all fine. Suggestions? Getting the battery registered and coded changed to an AGM type as soon as I can, but it would be nice to get these functions back.
October 17, 2016
  Followup from the Pelican Staff: Possible the terminals were shorted by accident damaging a control module. I would start by checking the vehicle for fault codes. If multiple systems are not working properly, fault codes will be set. This will be your best bet when diagnosing. - Nick at Pelican Parts  
Norwegian bimmer boy Comments: Its just the navi screen in the middle, not the dash speedo/rpm etcthat just keeps on rebooting! What can be the problem??
October 11, 2016
  Followup from the Pelican Staff: Ok, you originally said dash screen, not specific enough for me, had to guess at which screen you meant.

If the nav screen displays the BMW logo and is not starting, try holding eject on both radio and the Nav buttons & Volume power button for about three seconds, it should reboot. if that doesn't fix it, you will likely need a new navigation unit and programming. - Nick at Pelican Parts
 
Norwegian bimmer boy Comments: Hi again! Yes no faulty codes, checked at sutoshop. What is a cluster? Please respond to my email so i can reply my friend. Thank you!
October 11, 2016
  Followup from the Pelican Staff: The instrument cluster (panel). - Nick at Pelican Parts  
Norwegian bimmer boy Comments: Hi Pelican staff! Please i need your help! I have a 2009 bmw 320i coupe mtech e92? 2L 170hk. My dash screen shows the bmw logo, then works normal for 5 seconds or less then it freezes and reboots, over and over bootlooping. I was tipped that i had to change a "MPM MODULE" Do you think this is the problem or do i have to change the whole computer/player ? Where is the MPMM located in my car? Any tip will be highly appreciated! So horrible driving w/out radio/music/navigation... Please help! Contact me on mail. Salute from Norway!
October 11, 2016
  Followup from the Pelican Staff: Sounds to me like a faulty cluster. Have you checked the vehicle for fault codes yet? - Nick at Pelican Parts  
daled Comments: Nick, I have a 2007 328xi coupe I purchased a couple of years ago for my daughter. Since I purchased it, it starts okay but if the accessory is left on even for one minute, the battery light comes on the dash and it either starts very slowly or cranks but won't start. I was going to put a new battery in probably aftermarket and have my dealer program it. Is it odd that it continues to start but can't be left on accessory for even a minute for two years now?
September 27, 2016
  Followup from the Pelican Staff: it does seem odd. I would check battery voltage when the problem occurs. If below 12 volts, replace the battery. - Nick at Pelican Parts  
Perspect Comments: Do I need to have the battery registered if I only removed it to have it charged? Also, there looks like an extra connection that doesn't plug into anything. In figure 1 it is on the lower right hand side just below the yellow battery sticker with blue and red wires. I have the same connection and am hoping I didn't miss anything. Thanks
September 7, 2016
  Followup from the Pelican Staff: No. You do not. - Nick at Pelican Parts  
mikey Comments: thanks Nick - I thought there is a way to re register or program the key fobs?
August 18, 2016
  Followup from the Pelican Staff: Placing the remote key in the key slot should do it. If not, you will need a BMW scan tool to test the remotes. - Nick at Pelican Parts  
mikey Comments: After removing the battery for a load test - my remote key fobs will not open the doors. They work to start the car but no trunk or door lock function.
August 18, 2016
  Followup from the Pelican Staff: Something likely failed on your vehicle. Place the remote key in the key slot, if not recognized and keyless entry doesn't return, you will need to run a test using an advanced BMW scan tool. - Nick at Pelican Parts  
fcosau74 Comments: Hello Nick, I just changed Tha battery in my 2006 330xi, the old one had corrosion on the negative terminal; the car didn't start before the change and didn't start after, l've borrowed a scanner from Autozone to check for codes, when I checked for the battery it showed low battery even when is new. What should I do? Any reset that I have to perform?
May 28, 2016
  Followup from the Pelican Staff: You may have voltage drop. I would test battery voltage, then test battery voltage to the main fuse panel. Be sure to test the main battery ground as well. - Nick at Pelican Parts  
Daniel Comments: Hello, I have a 2006 330i and I smelt burning while driving. The positive battery cable is getting really hot and sparks when anything touches it. Any ideas on what might cause this?
May 26, 2016
  Followup from the Pelican Staff: Likely a short in the system. I would disconnect the battery and check the main battery cables for shorts. - Nick at Pelican Parts  
ALI Comments: Hi Nick, does Pelican sell BMW Scan tool that can be used for battery registration? I tried to look at the tools available but may have missed it.
May 3, 2016
  Followup from the Pelican Staff: Pelican may have one, best bet, Give our parts specialists a call at 1-888-280-7799.
- Nick at Pelican Parts
 
Joe Comments: Hi nick, changed the battery on my E90 318i, as one of the cells had died, the auto stop/start didn't work, I got told this was due to the dead cell, but it's still not working after the new battery, does it need initialising through the bmw scan tool for it to work?
April 10, 2016
  Followup from the Pelican Staff: I would assume there is a fault code stored, or possible the battery has to be registered. BMW scan tool is key here. - Nick at Pelican Parts  
pete Comments: Hi Nick, need some help, have replaced battery for e90 2009 bmw 318i, after replacing and registered with car, the airbag lights up in the dashboard, tried few times but couldnt get rid. Did we install incurrately or did we damage the distribution board on top of the battery?
Pete
February 20, 2016
  Followup from the Pelican Staff: Something may have been shorted or damaged. Start by checking for fault codes. - Nick at Pelican Parts  
JJ Comments: I disconnected the negative terminal before I replace valve cover seal after a week. Do I need to do anything special after I connect the negative tetminal back? Thanks.
January 25, 2016
  Followup from the Pelican Staff: No. - Nick at Pelican Parts  
Chris Comments: Is there a field expedient way to register a battery? I could reset the service interval on my e36 by jumping 9 and 17 on the service port, turning on the ignition and disconnecting the jumper after 10 seconds.
January 20, 2016
  Followup from the Pelican Staff: No. Only by using a BMW scan tool. - Nick at Pelican Parts  
Chayanne Comments: And nick r this engine colling sensor right? Are u suggest to replace the oil sensor to
January 5, 2016
  Followup from the Pelican Staff: If the sensor is faulty, there should be a code stored. I would start by checking the DME for fault codes. If the system is not working properly, a fault code will be set. This will be your best bet when diagnosing.
- Nick at Pelican Parts
 
Chayanne Comments: Thank u nick l just find out the sensor issue can u tell how much u can pay in,a indy shop for this work?
January 5, 2016
  Followup from the Pelican Staff: I am not sure what the repair will cost in your area. Call a few shops and ask for a quote. It is also a good idea to have them confirm what the issue is. - Nick at Pelican Parts  
Chayanne Comments: Hello nick l just had a question l have a 07 bmw 335i l had a problem ive replace my battery dec 31 but l never hook up a charger under the hood the car perfectly for one day until this jun 2 had a probelm bout tht the car was gettin overheated n then doesn't run even pusthe gas pedal until stop like 10 minutes n start it again but same problem also the cooling fan its on even if the car is cold so all this is because k didnt registered the battery right?
January 4, 2016
  Followup from the Pelican Staff: Unlikely. This sounds like a different problem. If the fan is on all the time, this could be a fault with the coolant sensor, a faulty DME or cooling fan. - Nick at Pelican Parts  
riggzee2 Comments: I change the battery in my 2006 325i as recommended. and have done this 5 years ago When I started it ATC, BRAKE, TIRE Alerts come on? Will these be cleared if I have the battery registered? Didn't before?
December 17, 2015
  Followup from the Pelican Staff: No, the lights are likely unrelated. I would start by checking the vehicle for fault codes. If multiple systems are not working properly, fault codes will be set. This will be your best bet when diagnosing.
- Nick at Pelican Parts
 
june Comments: don't know if my battery needed to replace a new one,summer and fall its all good starting,now cold times its not starting,jump start its running and drives fine,next morning same cause,not starting will have to jump again,.what could be causing it?my car 2006 330xi,.
December 2, 2015
  Followup from the Pelican Staff: You may have a parasitic draw. You'll want to monitor the draw on the battery when the vehicle is asleep. Here is a list of the specifications: http://autotechdiagnostics.com /?p=185
Once you confirm there is a draw. You will have to isolate the circuit with the draw. Then determine which components on that circuit is causing the draw You can isolate by removing fuses. be sure to have all the latches on the doors and hood closed (pin switches) so the vehicle will sleep during testing. If it wakes up, you will have to wait until it goes to sleep again.

halfpint Comments: Recently replaced the battery in my 07 E90 wagon due to it being slow to turn over and not starting when it got cold. The replacement battery is the larger 110V instead of the standard 80V. Again when it got cold, my car wouldn't start. The dealership is telling me that because the battery is larger that the IBS went bad/melted. Are they feeding me bull? It acted the same as it did prior to us replacing the battery, which makes me think the IBS was the problem all along. Thoughts?
November 30, 2015
  Followup from the Pelican Staff: Assuming you mean 110 amp hour. That shouldn't make a difference, as long as the battery fit. You may have had an issue with the terminal the entire time. - Nick at Pelican Parts  
ajazjohn Comments: Thanks Nick.
November 13, 2015
  Followup from the Pelican Staff: Glad to help. - Nick at Pelican Parts  
ajazjohn Comments: HI guys i am replacing my faulty IBS in my 2006 330xi, My ? is, after i put in new sensor do i need to register it. I am not changing the battery.
Thanks
November 11, 2015
  Followup from the Pelican Staff: You will need to program the vehicle to match the new IBS. - Nick at Pelican Parts  
PJ Comments: I have a "new to me" 2009 328i and the battery sound weak when starting. So I need to change out battery and am no where near a BMW dealer. So I feel the best way to change it out is to attach a motorcycle battery to the leads under the hood prior to R&R of battery as I have done in the past with my wife's Jag. That way the system doesn't loose power. Comment?
November 9, 2015
  Followup from the Pelican Staff: I do not attempt to keep a vehicle powered when replacing a battery. You could accidentally short the terminals and cause damage. - Nick at Pelican Parts  
czrrot Comments: Hi , my UK spec 320i doesn't have the ibs sensor on the negative cable. Does this mean my new battery won't need registering?
November 5, 2015
  Followup from the Pelican Staff: I am not sure about UK models, I have no info on them to check with. - Nick at Pelican Parts  
Welshy Comments: Got a bmw 325i e92 56 coupe. Need a new battery. Without sounding dumb, but what is the crack? Buy a new battery and put it in. Then what? Should it be ok or do i hav to get bmw to programme it? Sorry to not appear the brightest
October 11, 2015
  Followup from the Pelican Staff: As the article notes, you have to register the battery to the vehicle. This ensures proper charging and battery life. - Nick at Pelican Parts  
Scareysurfer Comments: Just got 335i 2008. Wouldn't start next day. Recovery came said I needed a new battery. Had one fitted AGM non-standard BMW. It wouldn't register when they tried. Reset clock and high battery discharge faults kept coming up. Replaced with another non-standard AGM. Problem disappeared. Next day, couldn't start car again. Recovery came and can't start this time. Eventually tow truck guy 'wiggles' module on top of battery and it starts. Took to main dealer today and had it replaced with standard AGM and registered. In your opinion do you think the non-start issues, high battery discharge messages and resetting of time and date settings are down to the battery not being registered or is there something else possibly going on. Was thinking IBS, 30g_f terminal, MPM relay sticking. I did have a code that recovery found which was A559 MPM intermittent fault but no date on it. Any help or advice would be much appreciated.
July 13, 2015
  Followup from the Pelican Staff: Sounds like the original installation had a cable loose. - Nick at Pelican Parts  
Derek Comments: When replacing the battery on a 2010 BMW 328i Sedan, do I need to recalibrate the steering angle sensor? Or just the registration and windows/sunroof/compass calibration?
June 3, 2015
  Followup from the Pelican Staff: The steering angle sensor should be fine. Just the other items you mentioned need to be done. - Nick at Pelican Parts  
Omar Comments: Hi, thanks for the guide! I am replacing my battery and ended up with this 'extra' connector, cant seem to find where it goes. not in the guide as far as I can tell. Any help is apprecited! It's an e93
May 18, 2015
  Followup from the Pelican Staff: That looks like a connection for the battery safety terminal. However, the eyelet end looks damaged. You may need to replace it if the connection is not secure.

Give our parts specialists a call at 1-888-280-7799. They can figure out what part or repair kit you need.

jt Comments: I un hooked the battery and re connected it 10 min later now car wont start and everything is flashing the whole car is spazing out its a 335 I 2007
April 26, 2015
  Followup from the Pelican Staff: Be sure the battery is charged and the terminals are tight and installed correctly. Then try to lock and unlock the left side door. - Nick at Pelican Parts  
VEES Comments: Hi guys i have a 2005 e90 330i.I had the starter replaced about 2 weeks ago.i tested the alternator which is charging fine.The problem is that when listening to the radio after 2-3 minutes the battery yellow light comes on reading the battery charge is low. Please help!!!!
April 25, 2015
  Followup from the Pelican Staff: Start by checking charging system voltage and current. - Nick at Pelican Parts  
Chris Comments: the charging malfunction light is coming on in my bmw 645. The dealership is saying I need an alternator. Could a unregistered battery be the culprit?
April 7, 2015
  Followup from the Pelican Staff: No. It MAY have caused the alternator to go bad though. When you register the battery you are telling the DME that the battery is new and does not need to be charged as intensively as an aging one. By not registering the battery you put in a battery without telling the DME to tell the alternator to adopt the less intense "new battery" charging strategy. - Casey at Pelican Parts  
Teson Comments: Hey nick what's the appropriate voltage on a battery BMW 328 I 2008? I
January 24, 2015
  Followup from the Pelican Staff: Open circuit battery should be 12.6 volts. Charging system will vary from a little under 13 to over 14 depending on demand. - Nick at Pelican Parts  
BigChoCho Comments: I took out my old battery on my 06 BMW 325i. S# 61 21 6 946 334. I figured my battery was bad. I put the multimeter to it after I took it out of the car and it shows 15V. It's not even hooked up to the car. I figured my meter was bad and used another one and I got the same results. Have you ever seen or herd this before?
January 22, 2015
  Followup from the Pelican Staff: Sounds like a surface charge. I have seen high static battery voltages before. - Nick at Pelican Parts  
alex Comments: I had to remove the battery completely to replace a one of the positive cables that had corroded. Do I need to use a bmw scan tool when I hook the battery back up?
January 14, 2015
  Followup from the Pelican Staff: Not if it is the same battery, as in not a new replacement. - Nick at Pelican Parts  
ADT Comments: Is the procedure the same for a 2008 335XI? That model is not listed above.
January 10, 2015
  Followup from the Pelican Staff: Yes, it will work for your vehicle - Nick at Pelican Parts  
twinky64 Comments: 2007 328xi e90
Update...after 100 feet of driving, the 4x4 light and brake icon light disappears. I suppose the ECU needed to confirm proper axle rotation speeds after the reset via battery unplug. Thanks
December 23, 2014
  Followup from the Pelican Staff: If you had a sensor fault code, then the control module sees the correct wheel speed, it will shut the light off. You may have had a wheel speed sensor error. - Nick at Pelican Parts  
Abed Comments: BMW 2008 328i - replaced the battery and then started to have problems with traction control and ABS . Service light started to go on an off and some time engine service light. I have been told that I need to re program the computer to recognize the new battery. Can I do that.
December 21, 2014
  Followup from the Pelican Staff: You do have to perform the battery registration process using a BMW scan tool. The ABS light may be unrelated. Check the vehicle for fault codes. - Nick at Pelican Parts  
twinky64 Comments: 2007 328xi
I removed the battery negative teriminal and reconnected negative terminal 8 min later. I am getting a 4x4 light and my brake icon goes from red to yellow when I disengage the brake.
November 16, 2014
  Followup from the Pelican Staff: Sounds like you set a fault or cleared an adaptation when the battery was disconnected. I would start by checking the vehicle for fault codes. If the system is not working properly, a fault code will be set. This will be your best bet when diagnosing.
- Nick at Pelican Parts
 
Charles Comments: My car is standing due to oil cooler problem, when I parked my car, I took out the positive terminal out off the battery. Now I want to replace that terminal back, I tried to use the key to open at back, but it is not opening. Help.
October 13, 2014
  Followup from the Pelican Staff: You didn't mention what vehicle you have. Try to unlock once, then unlock again a little further than before. This should open the trunk. - Nick at Pelican Parts  
Matt Comments: If I remove the negative battery terminal to perform a tune up do I have to use a BMW scan tool when I hook the battery back up?
October 11, 2014
  Followup from the Pelican Staff: No. - Nick at Pelican Parts  
nadir Comments: Recharging the battery via under the hood, do you put the fob in and press start, or you leave the key out of it all together?
September 13, 2014
  Followup from the Pelican Staff: Leave the key out of the key slot. - Nick at Pelican Parts
