93 190E ABS light on and off

Good afternoon,

first let me say that I recently found out about this site and I'm very happy that I did cause you guys have great line of products.

I just ordered the tune up kit for my 190E and looking forward to order some more parts.

however, the reason for this post is that I was wondering if you guys would know why the ABS light on my 190E randomly goes on and off.

I have a 1993 190E 2.6L and since I've got the car, this problem has always been there. Also I notice that every time the ABS light goes on, that the engine loses some power.

Also a while ago I changed the voltage regulator thinking that it may be a electrical issue, but the problem is still there. Could it be the ovp?

thanks,
Sean

89 190e ABS light on and off

I have a similar problem. I notice that the light comes on when I make sharp turns; especially left turns.

I am seeing and hearing of this problem much more often now as these cars get older. It can be very frustrating to try to troubleshoot and repair this annoyance. When the light flashes it may not necessarily mean there is a problem with the brakes, but for safety reasons it should be checked out The most common causes of an intermittent warning light are (1) dirty or faulty abs sensors at the wheels or (2) faulty electrical output/contacts.

First try removing and cleaning the ends of the sensors at all four wheels. Clean with a soft bristle brush and carb cleaner. Spray dry and replace. If no change next go after the electrical. Clean all relay contacts inside the abs cover and use dielectric grease on the contact pins. If no change consider replacing your OVP relay (over voltage protection). There is no guarantee but I have seen this fix the problem on a couple cars. If you are still having problems after all that then you should take the car to a brake shop familiar with Mercedes ABS brakes for thorough diagnostics BEFORE you throw more money at the problem.
