Dash and gages wont work

Our car did this early on in its life and was covered by warranty. However I got a notice later on that anyone having this problem could get a new instrument cluster from Mercedes. Must have been a major problem for the cars. Ask a dealer about this.

The instrument cluster on the vehicle is probably bad. You will need to take the car to a Mercedes-Benz dealership to have it replaced because it has to be programed to the car and the mileage needs to be set with a Mercedes-Benz scan tool.
