I just bought a 95 c280 for my wife and I noticed the cluster is not working 100%. The RPM gauge, fuel gauge and the temp gauge are all not working. The speedometer and odometer are working fine and so are all the lights. Anyone have any idea where I should start looking? Another thing is the car runs perfect when cold, strong smooth and full of power but when it warms up it starts running a little rough, as if it were missing. Any suggestions? I should add that the car has all service records and appears to be in near perfect condition. I thank you all in advance.
