Hi I was wondering on an 02 clk 430 cab I have about 36,000 miles on but I wanted to replace my cluster do to some bad LED elements, What would I have to do if I replaced with a used cluster with more or less miles on it, will it read correct or error and if it errors how do I fix it?

 

the mileage is stored not only on the instrument cluster, EIS and electronic shift module but on the engine control unit too.

once the instrument cluster is ridgidly assigned to a car, you cannot change the reading anymore.

you may try to adapt it from the engine control module, but it can't on others.

most probably, you can't start or shift the gear.
