Hi,
I have a 528i, E28 1985, I bought it and have been repairing / restoring it.
Everyting is fine except the ABS light is on.
When the ignition is turned on the light is on.
As soon as the engine starts the light goes off.
If I drive real slow (10km/h) light stays off. If I press the pedal I can feel the ABS pulsing the pedal.
If I go faster (about 20) the light goes on and stays on.
The rear rotor sensor on one side was rusted, I wire brushed and rust treated it.
I checked the front and all appears fine there. Cleaned the sensors and rotors also.
As the front are plug in, I checked and saw the same resistance on both. I cant find where the rear sensors are plugged (I am guessing inside the cars interior somewhere, as they are one peice from sensor to inside of floor (from underneath.
I checked and I have 12v on the large relay (all the time) and I got an ingition 12v on the small relay.
Any suggestions where I can look and check?
Thanks!
