Having problems with abs on my 190E 2,6. The abs lamp "lights off" as ordinary when i started the engine, but after approx. 10 seconds its lights up again. I have checked all relays on the ABS unit they seems to be ok b'cause all of them have been changed by earlier owner, no oxidization on the connections either, The ovp is changed, all ABS-sensors seems to be changed by earlier owner, they are magnetic as h*ll
do you have any clues about what it can be?
