1990 Mercedes-Benz 300E Q&A
1990 Mercedes-Benz 300E Question: The ABS light stays on, but brakes are okay. What's could be wrong with it.
The ABS light means that the ABS system has been shut off because there is a problem with the ABS system, you will just have regular brakes. It should not have much to do with your car running rough at stops. You need to have the ABS system checked for codes and the rough running also needs to be addressed. How long since your last major service? - dandd

it is most likely the ovr switch. Just changed mine out , had the same problem and now the car runs perfect. Just had to move the battery a little to get my big paws in there and take one bolt out and unplug it to get it out. Not much to it. takes 10 minutes to do - Visitor
