On my 02 E430 - when the interior of the car is warm/hot the speedometer needle will jump 1 - 3 mph increments (sometimes more) when I accelerate to change speeds - rather than smoothly rotating to show the increase in speed.

It seems like this is a problem with the instrument cluster - however, when I bought the car with 44k and the service history indicates the instrument cluster was replaced around 33k. Now the car has 54k on it (although I noticed the problem last year, maybe at 50k).

Are these clusters really that bad that they last less than 20k?? Or is there something I can do to resolve the problem without replacing the cluster.

I appreciate the ideas/input....
