There could be something wrong with the ABS system and check the ABS sensors on all wheels. Also check the connections to the ABS unit and the traction control button.
Not totally sure, is it just the ABS light, or is the ESP light also going on/off? Could be a faulty stop lamp switch located on the brake pedal, or could be something going on the the SBC system? If the ABS lights has come on though, there should be a code in the system.
You have a problem, take it to Mercedes agency.
Why is my 97 mercedes e420 abs and esp warning light on?
That means you have a problem with the ABS. Take it to an agency to check it.
Bring to a shop that has an ABS scanner to determine problem
Your ABS light being on indicates that the ABS system is not functional. You need to get it checked otherwise you would be driving a car without the safety of Anti-Lock Braking System(ABS).
The abs light came on because there is a problem with the abs ( Anti-lock Brake System). The abs light will not reset until the problem has been fixed. Once the abs system is repaired the light will reset itself.
The ABS computer has detected a malfuction and set a code.
ovp relay
You may have damaged an ABS sensor or ABS sensor wiring. Go back and check each wheel.
First take a look if the ABS light is on, if yes, check your OVP relay.
It could be your Brake Light Switch. My 2001 E430 wouldn't go into gear from parking and the ABS ASR light was lit. The switch cost about $24.00. It is located behind your brake pedal.
