Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hi, it sounds like you still have a bad overvoltage protection relay or the fuse in the relay has blown or there is no power getting to the relay.
Does the ABS light come on as soon as you start the car?
There is a small wire that connects to the positive battery cable at the battery in the trunk. The wire powers the overvoltage protection relay. Check to see if that wire is secure.
Just checked wire is good . The relay is new . i do have power going to it
Did you make sure that the fuse is still good in the relay? How high are the engine rpms? Does the ABS light come on as soon as you start the car?
Just recheck fuse.I replaced just to be sure. abs light comes as soon as i start. idle at 1500 to 1700. even after letting car get to opperating temp
What happens when you disconnect the plug at the idle control valve. Does the idle go even higher?
