i have the same problem. asr light on- it seems like a 6000 expense, i dont know if there is any way around it. both actuators are out and a new harness is needed too.

Can't the ASR just be disabled? It's a worthless crappy outdated idea that should be removed from every car, not just MBs. People should ride in a city bus if they don't want to drive. Slipping around a little when the road is wet and knowing how to handle it are parts of driving.

Americans become less and less adventurous every year. And don't mention the safety factor or other liberal rallying screeches. Just as many people die today as 20 years ago from spinning a tire at a stop light. Pretty much zero. Have you seen that person trying to get up that snow-covered hilly road but can't? It's because they have the ASR turned on.

Pull the plug.

I've had a 500SL (1991 model) since 1995. It's a great car, but the problem you describe does occur occasionally.
I take it to my friendly Mercedes dealer, who do the same trick every time to resolve it. All they do is adjust the throttle cable; tighten one notch I think.

I think this only affects the pre '95 cars, as at some stage in '95 the SL became a "fly by wire" vehicle.

Good luck.

Graham.

how about the cheap way is to clean the abs speed sensor then change the brake light switch.

I think I have the solution for you...
Please tel me if the light comes 'on' if you start the car keeping your foot on the brake?
If 'NO' i'll tell you the secret!!!
I had the same problem and it's very simple...works like a charm...

You may want to look at this info. http://pages.prodigy.net/jforgione/MB_asr.html
I am dealing with the same issues. But the ASR seems to shut off when the car is warmed up after about 15 miles of driving. It sounds like he figured it out. Not cheap though.

I had a problem with a 1993 300e 3.2. The ASR light comes on when cold and I had to press accelerator 3/4 down until I got a response from the throttle. I happened to turn on all the lights the rear defroster the heater fan and all of a sudden the throttle response was normal. I turned off all the electrical stuff and the problem came back. I measured the voltage at the battery and it was 18.8 volts. I turned everything back on and it fropped to 13.5 volts. Replaced the OVP and that cured the problem.
