Hi , I have the ASR problem i have read so much about on this forum. I have a 1990 500sl and it has only recently developed this fault. The strange thing is, when i slightly adjust the slack out of the throttle cable, the light goes out and the car comes out of limp home mode. Sometimes it lasts for weeks, sometimes it needs more tweaking. recently this has stopped working and the asr stays on and in limp mode. With the cable adjusted even more, the car idles too high and seems to have a mind of its own in the rev range. However with careful adjusting i can get the asr mode off and the car idling right BUT as soon as i even breathe on the accel pedal, ASR ASR !!! aaargh.

My questions are these, if anyone can help :
I have read lots about people changing the brake switch - does this seem like a suggestion for me ( i'm not sure as the accel pedal touch relights the asr )
Also, i heard something about the OVR Over voltage relay ? Reason i ask is tha my car was jump started and i think thats where all this started.

Any help greatly appreciated, as my grin is now
