    ABS Return Pump Malfunction

    I had my ABS/Brake warning lights come on while driving my Z8. No problem with the braking functions, including the ABS system could be noticed. I took the car to my BMW dealer to have this checked. Dealer says the problem is a faulty ABS Return Pump. They cleared the code and it stayed off for a while but then the warning lights returned after a short drive. Dealer says pump cannot be repaired and must be replaced. Cost: $4,195.00 and the part must come from Germany. I am wondering if more driving might correct the problem and perhaps I should have the code cleared again. Again, no braking malfunction can be detected while driving. Everything works just fine. Has anyone had this problem? Any other suggestions for correcting this problem.

    Seems $4000 has become the baseline repair charge on our cars. 🤔

    Is it possible the ABS pump is shared with other BMW models of that era? If so, you might be able to find a good used one for considerably less.

    Good idea. Perhaps the same pump as the M5 or even the standard 5 or 7 series. I will look into a good used one. Thanks.

    How about looking up the part # RealOEM.com - Select Your BMW Model (wish I was good enough to do that for you) and then ordering from a place like www.getbmwparts.com

    Then finding an independent shop to do the install?

    Edit, better information here;

    If it turns out to be the same part as used on the E39 M5, there is a guy on the M5 forum who parts out exclusively E39 M5s and is a go-to guy for the E39 crowd. I have used him on a couple of occasions for items I needed for my E39 M5. https://www.m5board.com/threads/clem...3#post-7638768

    Thanks. I need to determine if this part is, in fact, interchangeable with other models. I can then check for that parts availability.

    Thanks. Another very good suggestion.

    If memory serves, the braking system for our cars comes from the e38 750iL security (super heavy bullet proof). Those cars are rare, but maybe one has been “shot up” in some banana republic.
