ASR and ABS lights on randomly

I have a 95 wagon and the ASR and ABS warning lights both come on and stay on ocassionally when I start up the car. Maybe every 5th time I start it up. I can shut off the key and restart it and it usually goes away. I know that when the lights are on, those systems are not working. I've had the dealer look into it, but they could not solve it. Any ideas?

Does it ever turn on while driving?

Nope. Just turns on at start up and stays on until I turn off the car, and restart it.

I searched the board and found these as potential causes:

- check fault code indicator readings should help determine where the problem is
- On some cars that's an indication of a low voltage condition caused by a faulty voltage regulator
- brake lamp switch needs to be replaced
- battery or alternator apparently when the voltage is low, those lights come on
- overvoltage protection regulator
- wheel sensors
- faulty wiring harness

If you've been around this board long enough (i've been around about 5 years), you'll know very well that the over voltage protection relay is a common electrical trouble-maker in the w124 series cars. I'd replace that before you do anything else. $45 for a new one.

Thanks. Hopefully the mystery will be solved tomorrow. I'll report back.

If it was during drives it would point to bad speed sensors.

In this case I second the OVP. There was an update on the OVP. Make sure your car has the new version.
Other than that you might have a problem with the alternator or the ABS/ASR module.
