ASR Light

Hi, I'm living in Thailand.
My W140 320 SEL go the same issue of the ASR light. I get it fix by open up the control unit at the air intake, the unit that the lock cable going in.

Inside you will find the insulator of wires are broken, you may need to touch some cable joint with soldering, I also clean it up and it never give me the problem since, that was two years ago.

I hope this can help.

Have your ASR codes read. Without it, there can be *lots* causes.
Have a look here for codes (up to 06/94);

or here (from 06/94 to 08/95);

or here (from 08/95);

The most common cause for ASR lamp on these, must be
S9/1, brake lamp switch;

al limp mode

my understanding of LIMP MODE is a feature that MB put as a safety feature/program that activates when something in the fuel or transmission does not work properly. keep in mind that the electronic wiring in this car goes in a cicle from computer to fuel-MAF-oil-etc so when somethings is bad it brakes the circle and the LIMP MODE activates...... Limp mode is whatever the spped you are going and activates it tells the engine (STOP NORMAL DRIVING SLOW DOWN) meaning if you are going at 60mph you have to slow down and goes to 3rd gear than 2nd and last first gear that way the engine stay running at low RPM stay in first gear so you can reach a mechanic, it can go to 2nd gear if you press the pedal to hard and rev it at high rpm but i would not sugest it, also if you turn the car off take the key out 4min the car car will turn off fine with out the limp mode untill it gets activated again and fix the issue, sometimes electronic stuff acts up but dont worry stuff happens, now if it happens more than 4 times than yes look in to it,,, hope this helps
