BMW X3 ABS Light + Traction Control Issues, Need Help

Hey there! I had a similar issue with my 2008 BMW X5 3.0i last winter. The symptoms you're describing match exactly what I experienced, ABS light, jerky acceleration, and unstable traction control. Turned out my ABS control module was defective and one wheel speed sensor was shot. Took it to the garage and they confirmed the control module was sending incorrect signals to the system. They had to replace both the ABS module and the faulty sensor. It was definitely a serious repair since it affected the car's entire stability control system. Not something you want to postpone fixing, as it compromises your vehicle's safety systems. The repair took about two days total including diagnostics and parts delivery. The car has been running perfectly since then, no warning lights or traction issues. Would suggest getting it checked soon, as driving with faulty ABS can be risky, especially in emergency braking situations. Hope this helps with your decision.

Thanks for sharing your experience! That's really helpful since our issues sound identical. I'll definitely get it checked out soon based on your advice. Mind if I ask how much you ended up paying for the whole repair? Also, curious if you've had any other ABS-related problems pop up since getting it fixed? My wallet's already crying thinking about BMW repair costs, but safety comes first!

Hey again! Happy to report that after getting my X5 fixed, I haven't had a single ABS-related issue, it's running smooth as silk! The speed signal fault is completely gone, and the traction control works perfectly now. Money-wise, I ended up paying 1000 € for replacing the defective control unit, and honestly, while it wasn't cheap, it was worth every penny for the peace of mind. I totally get your concern about BMW repair costs, they can definitely make your wallet lighter! But since having it repaired, the car handles like new, especially during quick acceleration and braking. No more jerky movements or warning lights to worry about. Just make sure whoever works on it knows their way around BMW systems, these cars can be a bit finicky with their electronics. Looking back, I'm really glad I didn't put off the repair. Having reliable ABS and traction control is crucial for safe driving. Let me know how it goes when you get yours checked out!

Thanks so much for all the details! I bit the bullet and took my X3 to a mechanic yesterday. You wouldn't believe what happened, turned out it actually was the wheel speed sensor and control module, just like your case! The mechanic was super honest and showed me the faulty parts. Cost me about 850 € in total, which wasn't as bad as I feared. They had to order the parts and keep my car for two days, but wow, what a difference! Just picked it up this morning and test drove it, no more jerking, no warning lights, and the traction is perfect again. The braking feels so much more confident now. Funny how I was stressing about finding a good mechanic, but this new place really came through. Should've done this weeks ago instead of worrying about it. Thanks again for pushing me to get it fixed, your experience really helped me make the right call!
