It's inevitable--one day, one of the lamps will burn out in your gauge cluster. Most people just tolerate this because, in their minds, the bulbs are difficult to reach and nobody knows how to get to them anyway. In reality, it's quite easy if you know the procedure for safely pulling out and removing the gauge cluster.

The first step is to disconnect the battery. With the battery connected, it is possible that disconnecting the cluster can trigger the airbag light as the computer thinks something is wrong with the system. Unfortunately, you'd need to visit the dealer to have this light reset.

Make sure you have the proper radio code required to reset your radio if you do disconnect the battery. Nothing is more frustrating than realizing your radio is dead and you don't have the code. It is available from your local Mercedes-Benz dealer, upon showing them proof of ownership such as your vehicle registration.

The instrument cluster on the Mercedes W210 chassis simply pushes into the dashboard.
Figure 1

The instrument cluster on the Mercedes W210 chassis simply pushes into the dashboard. You remove it by using two picks in the area shown here (green arrows).

As the cluster is removed, you can see the gated part of the cluster on the side where the picks fit into the sides of the cluster (green arrow).
Figure 2

As the cluster is removed, you can see the gated part of the cluster on the side where the picks fit into the sides of the cluster (green arrow). Pull the cluster out a half inch at a time alternating between the left and right sides. Eventually, the cluster will pop out.

On the backside of the cluster are two electrical harness connectors.
Figure 3

On the backside of the cluster are two electrical harness connectors. Press the tab (green arrow) and rotate the locking tab (purple arrow) down. This will unlatch the electrical connectors from the instrument cluster.

Shown here is the backside of the cluster.
Figure 4

Shown here is the backside of the cluster. Our project car is 15 years old, so I opted to replace all of the light bulbs at the same time. Depending on the year and model of your car, the bulb locations and wattages may have changed. Look at the back of the cluster. There should be text molded into the housing that tells you the bulb size and wattage. In our case, the green arrows point to 12V-1.2W bulbs with a blue base, the yellow arrows point to 12V-1.5W bulbs with a beige base, The purple arrows point to 12V-1.5W red bulbs with a brown base and the red arrows point to 12V-2W bulbs which re-use the yellow base.

Replace the bulb housings by turning them counter clockwise and lifting them out of the instrument cluster with a pair of needle-nose pliers.
Figure 5

Replace the bulb housings by turning them counter clockwise and lifting them out of the instrument cluster with a pair of needle-nose pliers.

Two of the bulbs re-use the yellow bulb housing shown here.
Figure 6

Two of the bulbs re-use the yellow bulb housing shown here. Pull the old bulbs straight out of the housing. When inserting the new bulbs, use a paper towel. The oils on your fingers can cause a hot spot on the glass of the bulb, causing it to burn out prematurely.

The smaller bulbs behind the information display have a 6mm nut molded into the housing.
Figure 7

The smaller bulbs behind the information display have a 6mm nut molded into the housing. Use a 6mm socket to remove these. Once all the bulbs have been replaced, reconnect the electrical harnesses and push the cluster back into the dash.

catalogkid Comments: Thank you Nick for the heads up on the DRL Module. this car is new to me. Just spent 45 min. looking on line for the location of this part. No luck. can you please give me an idea where it is? Thank you so much. 1990 300sl.
September 7, 2014
  Followup from the Pelican Staff: See attached. - Nick at Pelican Parts
catalog kid Comments: Low beams not working on a 1990 300sl Mercedes. New switch, needed replacing found no power at the low beam fuses. There is power to the high beams, Where d I look next?
September 6, 2014
  Followup from the Pelican Staff: Check the power feed out of the drl module to the fuses. - Nick at Pelican Parts  
sil Comments: Hi Nick, do you have a tech articles on cruise control not working and really high idle. This is a 97 E320 w210.
August 23, 2014
  Followup from the Pelican Staff: Not currently. I would check for broken vacuum hoses or detached breather lines. CHeck the intake air duct to eh throttle housing to start.- Nick at Pelican Parts  
Sil Comments: Thanks Nick, I will call on Monday since you're closed on Sat. Is any of these bulbs specifically for the CEL illumination. Mine is not lighting up, and I'm assuming that the bulb may be dead or is that on the circuit board?
August 16, 2014
  Followup from the Pelican Staff: Could be the bulb, the wire from the cluster to the DME (comes out at connector 2D, pin 2). - Nick at Pelican Parts  
Sil Comments: Hi, I have a 96 E320 with one or two dead cluster bulbs. I will like to replace all the cluster's bulbs with LED bulbs, but I do not create another unwelcome problem. What is your take on my idea, are the holes and the base size all the same? By the way, I did not see LED bulbs on your website.
Your suggestions will be appreciated.
August 15, 2014
  Followup from the Pelican Staff: I would stick with the bulbs the cluster was originally equipped with. Otherwise it will be trial and error. Give our parts specialists a call at 1-888-280-7799 and they can help figure out which part or repair kit you need.

Christina Comments: The dials on my instrument panel click all the way back when I turn off my car. This happened after I had my car washed I think they m may have tried to wipe plastic front plate but there isn't one there. Is there a way to reset the dials so they don't move ask the way back.
August 8, 2014
  Followup from the Pelican Staff: YOu didn't mention what vehicle you have. If the gauges were touched and the needles moved, the luster will have to be disassembled and reset. Likely by a rebuilder. - Nick at Pelican Parts  
Tuanhenry Comments: I have 1997 C230. the instrument working fine only when the night come I turn the light on, but the light in the instrument panel not on, any thing work fine, only when turn the light on when the night time come in, the light in the instrument panel light not on. I was change 2 bulb 15v 2w already, but still same problem. Some one can help me what wrong.
July 24, 2014
  Followup from the Pelican Staff: If you the bulbs are good and you have power to the cluster from the lighting control, the cluster itself may be faulty. They are problematic. - Nick at Pelican Parts  
zerosofthezeta Comments: The Mercedes technician quoted me $550 while looking me straight in the eye. At the time, I only had one light out, but now I have the whole right side out. This article helped me so much and saved me $550! I can't thank you enough!
July 24, 2014
  Followup from the Pelican Staff: Thanks for the additional info and feedback. We appreciate it.
- Nick at Pelican Parts
 
dan Comments: I just bought a 1997 S320 Mercedes. The instrument cluster illumination dimmer doesn't work. I have removed the cluster and checked all the bulbs. They are all good.
I did replace the ambient temperature bulb. Any suggestions on how to check out the dimmer control?
June 15, 2014
  Followup from the Pelican Staff: The problem could ne the dimmer switch. - Nick at Pelican Parts  
dralloc Comments: Sounds good. I will take a voltmeter to the ground connections on the cluster. Where do I check- at the two side connector points? sorry not electrically inclined but it seems simple enough. Looking for less than 12 volt reading? If it shows a drop do I have to replace the cluster then?
June 13, 2014
  Followup from the Pelican Staff: You will want to test at the harness side. Ground should be almost zero volts. I would grab a repair manual, it will have the wiring diagrams. - Nick at Pelican Parts  
Dralloc Comments: Nick thanks for the feedback on the cluster light dimming. Would a power or ground issue come up as a problem code if I plugged the car into a code reader? Is there anything I could do as a DYI person or would I need to have it inspected by a mechanic?
June 11, 2014
  Followup from the Pelican Staff: It may shows as a code, if it has a voltage drop (lower than expected voltage) it may not show s up as a code. You can check the power grounds at the cluster, voltage drop test them. This is the nest step. - Nick at Pelican Parts  
Dralloc Comments: Thanks for the advice. Went ahead and changed out my dash bulbs in a flash. Only problem is that my issue hasn't been fixed. After about 1 hour of driving the odometer/time/temp display is still fading out. What do you think is the issue?
June 9, 2014
  Followup from the Pelican Staff: Could be a faulty cluster or power / ground issue. - Nick at Pelican Parts  
Chuck Comments: I would like to change out the headlight bulbs high & low beam for the high intensity bulbs that you have on your site. Do you have a tech article for DIY?

keith Comments: need to change a knock sensor on a 1997 e320. can u help
May 30, 2014
  Followup from the Pelican Staff: We don't currently have a tech article for that procedure. See here for what we have: http://www.pelicanparts.com/techarticles/MBZ_Tech_Index-W210.htm

I would grab a repair manual. It will have the procedure, special tools and torque specs.

Give our parts specialists a call at 1-888-280-7799. - Nick at Pelican Parts
 
Dralloc Comments: Thanks for the response for the light bulb change out question on the seat adjustment controls on the front door panels. Since Im not experienced with removing interior door panels, where are the panels attached to the door and what tools if any would I need to remove the panels? Also am I in danger of damaging any clips holding the panels in place? Also regarding your response to another question on removing the cluster from the front dash of an E320 1997, I can see how to remove the cluster using the two pics you show but how do you get the cluster out enough from the dash in order to place those two picks? Ive tried to gently pull on both sides with downward pressure to bring out the cluster enough to place the two picks but it won't budge.

The cluster may be stuck, you may need a stronger hook tool for leverage. - Nick at Pelican Parts
 
dralloc Comments: I have a 1997 Mercedes E 320 and the light that outlines the seat adjustment controls on the door are out. how do I access the back of the control and which bulbs do I need?
May 12, 2014
  Followup from the Pelican Staff: If I remember correctly, you have to remove the door panel. - Nick at Pelican Parts  
Goose nizzle Comments: I removed all my bulbs and replaced them with led bulbs and everything went smooth uuntil I got greet and did one more ...not sure what I did but now all light inside cluster stay on even if the car is off with no key...any suggestions.

Marc B. Comments: Hi I've got a w202 c280 and can seem to be able to remove the tiny T5 bulbs from their socket/holders. I'm trying to replace the bulbs. Is there a trick to pulling them out of the socket without breaking the bulb?
February 15, 2014
  Followup from the Pelican Staff: The bulbs may not come out of the socket, you may have to replace the socket with the bulb. Give our parts specialists a call at 1-888-280-7799. They can help you find the right bulb. - Nick at Pelican Parts

dude Comments: 1998 ford burned how to replace it
January 26, 2014
  Followup from the Pelican Staff: Not sure what you mean by burned? - Nick at Pelican Parts  
Island boy Comments: I have a 1993 Mercedes 300SE and the Odometer has stopped working. I took it to a local MB dealer and they told me that the part alone would cost approx. $1600, however, they did not have the part. Can you recommend a more economical solution? I am now on a fixed monthly retirement and I cannot afford $1600 plus labor to fix the car. It is in excellent condition, both inside and out and I really would like to keep the car. It had about 132k miles when it went out 8 months ago.

Thank you for any assistance that you can provide.
January 26, 2014
  Followup from the Pelican Staff: You can send the cluster out to an automotive electrical repair service. They may be able to repair it for a few hundred dollars. - Nick at Pelican Parts  
amber Comments: hi I recently replaced my cluster as the lights went dim in it. my car only had 87,000km on it but the new cluster now reads 250km how do I if possible fix this to its actually 87km?
January 7, 2014
  Followup from the Pelican Staff: You will have to visit a dealer to see if they can do it. They will likely be able to make the adjustment. You may have to provide documentation of the old mileage. - Nick at Pelican Parts  
jeffrey978 Comments: Thank you for this 'how to' description. We just purchased a 2002 E320, and the daylight test drive didn't reveal the fact that the transmission gear and time display on the right side of the dash cluster is not illuninated. I am handy enough to do the bulb replacements, but don't understand the specified tool, i.e., a set of picks. Do you sell these picks, or can you describe them? Thanks
December 26, 2013
  Followup from the Pelican Staff: A standard small pick set. Give our parts specialists a call at 1-888-280-7799. They can help you find the right picks.

November 29, 2013
