in my 89 190e 2.6...

However, I may be facing an OVP relay issue which causes my ABS light to come on very occasionally...and causes my car to stall intermittently.

From time to time, and usually when I apply the brakes upon the first stop after pulling away, the brake slightly pulsates and I can hear a clicking noise. It may happen at other times during the drive as well.

My brakes are quite spongey so I'm chalking this up to a pad/rotor isssue, and not a malfunction of the ABS system...although you never know. I'm gonna pull the wheels and check the pads and front pad sensors to see if there is an issue there.

I'll let you know what I discover as it may shed some light on your situation as well...however, in the meantime, please reply here or email me at kevock@amnh, if you happen upon a solution to the problem.

Sorry, I cant be of more help as I'm piggy-backing on your problem.
