How to remove the instrument cluster from an ML Class W163

This repair guide provides step-by-step instructions, along with pictures and a video, on removing the instrument cluster from the dash on a Mercedes-Benz ML-Class. This guide is applicable to models manufactured from 1998 to 2005. In our situation, we needed to replace two of the T-10 miniature light bulbs. Click here to go to Amazon and order the correct light bulbs. Cool tip! Different-color bulbs or LEDs can alter the appearance of the cluster illumination, although the final color and brightness depend on the cluster’s original optics and bulb type, such as red, yellow, and blue, to change the background color of your dash; links are provided below. You will not get a warning for using incorrect bulbs in the cluster if you use LED light bulbs.

With these light bulbs burned out, the instrument cluster was partially lit up, making it challenging to see the speed, especially at night.

To remove the instrument cluster, allow approximately 30–60 minutes for a first-time DIY removal, depending on the vehicle’s trim condition and your familiarity with interior trim removal. It can be done in less time, but you don’t want to rush, damage the dash, or break any clips. Use a plastic trim-removal wedge rather than a metal screwdriver whenever possible. Older W163 interior plastics and retaining clips can become brittle with age.

This is an easy task that can be completed if you have never removed a cluster. On a scale of 1 to 10, with 10 being very difficult, this is a 3 or a 4. You can remove this cluster and install it back in place with some patience.

Parts Needed

Two T10 Wedge Light Bulbs. You can use LED bulbs and change the color of the instrument cluster background. Click on any of the links below to order the correct bulb on Amazon.

Step-by-Step Instructions. (Pictures)

Instructions on how to remove the instrument cluster on a Mercedes-Benz ML. Instructions online recommend removing the steering wheel, but the steering wheel does not normally need to be removed. Lower and extend the steering wheel/column as far as possible to create clearance for the cluster.

Extend the steering wheel down as far as you can.
Remove the plastic pieces on the right and left of the steering wheel using a plastic wedge (prying tool).
Remove the instrument cluster bezel. Release the retaining clips on the left and right sides of the cluster bezel, then carefully pull the bezel downward and away from the instrument panel.
Remove the two bolts that hold the instrument cluster in place. These bolts are on the left and right of the instrument cluster and can be removed using an 8 mm socket.
Loosen the two plastic retaining fasteners along the upper edge of the instrument cluster.
Pull the cluster forward far enough to access the electrical connector. Release the connector’s locking tab/lever, then disconnect the connector. Do not pull on the wiring.
Remove the instrument cluster from the dash. If you remove the steering wheel, this task will be easy. If your steering wheel is in place, removing the cluster may be a little tricky, but it can be done.
Remove the instrument cluster illumination light bulbs. It would be best to twist the bulbs counterclockwise and then pull them out slightly.
Install new light bulbs. To change the look of the instrument cluster, you can install different color bulbs and links provided above.
Install everything in reverse order. Before fully reinstalling the trim, reconnect the battery and switch the ignition on. Verify the instrument illumination, gauges, warning indicators, displays, and adjustment buttons operate correctly. If everything works normally, reinstall the remaining trim. After reconnecting the battery, some vehicle settings may need to be reset or resynchronized. Check the owner’s manual for the applicable procedures.
