My son has aquired a fairly clean 87 325is and I'm in the process of
working out the kinks. One of the things I have noticed is that
sometimes the ABS light goes out and sometimes it doesn't. Another
thing that has me guessing is that sometimes when the light is out
(ABS system says it's OK), the brake pedal will pump while sitting at
a dead stop. This is the first time I've seen this behavior. Anyone
else seen it and possibly know why?
Mine started doing this once after we had done fairly extensive work in the
back end (clutch -- ie driveshaft and new rear guibo, and then rear wheel
bearings both sides 1 month later).
While we were down there we noticed the abs lines looked a little rough.
The guys in the lists think this is probably what's at fault.
My ABS light will come on sometimes, after which ABS is down. Other times,
it works fine.
I'm going to replace the lines when I get time.
