<E28/E30>ABS

[dchez@xxxxxxxxxxxxx]

Do any of you E28 experts out there know if there is also an ABS overcharge 
relay on the E28's as the E30's had and where it is located?  On my '87 535is, 
the ABS light has never come on (not even when starting the car).  The 
previous owner told me when I bought it that the ABS didn't work and he was 
willing to negotiate on the price since he knew it might be expensive to fix.  
I've confirmed that it is defective by sharply applying the brakes in a wet 
parking lot and noticing the wheels locking up.  Are there any other items to 
look for?  Thanks in advance for any advice.

>Good luck, and let us know what happens,
