Irregular gearshifts and warning signals in a 2007 BMW X3 Diesel: experience and advice wanted

Hi, I recently had a similar problem with my 2010 BMW X5. I also had erratic shifting and the ABS light was constantly on. Upon visiting the garage, it turned out it was actually a problem with the transfer case emergency gearbox and the ABS sensor. The grinding noise was causing a problem with the brake disks. They weren't minor problems, but once they were fixed, my car ran like clockwork again. So my advice for you is to go to the nearest garage immediately and get it checked. Hope that helps you!

Hey, thanks for the tip! So is it true that it could also be a problem with the brake disks? Do you happen to remember how much the repair cost you? And have there been any other problems with your car since the repair?

(Translated from German)

Hey, no problem! So, as for the brake discs, yes, it could definitely be a problem with those too, but your mechanic can tell you that after a thorough inspection. As for the cost, it cost me around €525 to repair the control unit that was faulty. Fortunately, I haven't had any further problems with my car since then, and the problem with the transfer case emergency running control has also been fixed. I hope that answers your questions!

Thank you very much for the detailed information! It really helps me. Your experience gives me hope that it's nothing serious. I'll take the car to the mechanic today and see what he says. The main thing is that my car runs just as well as your BMW X5 after the repair. Thanks again and hopefully your car will continue to be problem-free!
