BMW iX2 ABS Light Mystery: Traction Control Acting Up

Hey there! I had a similar issue with my 2021 BMW iX3 last year. The symptoms you're describing match what I experienced, ABS light staying on and traction control acting up. Turned out the control unit was defective, not just a sensor problem as initially suspected. When I took it to the garage, they ran diagnostics and found communication errors between the ABS module and other systems. They had to replace the entire ABS control unit. It wasn't a quick fix, my car was in the shop for three days as they needed to program and calibrate the new unit. This is definitely something you shouldn't ignore, as it affects crucial safety systems. In my case, it was covered under warranty since these units aren't supposed to fail this early. I'd recommend getting it checked soon, ABS issues aren't something you want to gamble with, especially in a newer vehicle like yours. Hope this helps with your decision-making.

Thanks for sharing your experience! That sounds pretty much identical to what I'm dealing with. Good to know I'm not the only one who's run into this. Would you mind sharing what the total cost was for the repair? Also, just curious, have you had any other issues pop up since they fixed it? Trying to figure out if this might be part of a bigger problem I need to watch out for.

Hey again! Happy to give you the update! I actually just paid for the repair last month, it cost me 1000 € to fix the faulty control unit. But honestly, it was worth every penny because the car's running perfectly now. That annoying Speed signal fault that was causing all the trouble? Completely gone! The best part is I haven't had a single problem since the repair. The traction control is working like a charm, and the ABS light hasn't flashed once. It's such a relief to have the car back to normal. From what I understand, these control unit issues are pretty isolated, not typically part of a bigger problem. My mechanic seemed familiar with the issue and knew exactly what to do, which was reassuring. If you're still worried, just keep an eye on your dashboard for any new warning lights, but I really think once you get this fixed, you'll be good to go. My iX3's been running smooth as silk for the past month. Let me know if you need any other details about the repair, happy to help!

Thanks everyone for the helpful feedback! Just wanted to update you all on what happened with my BMW. Finally took it to the shop last week after gathering all this info. You guys were spot on, it was the ABS control unit causing all the trouble. The mechanic I found was actually great. Did a thorough diagnostic test right away and showed me exactly what was wrong. Got it fixed in two days, and while the bill was around 900 bucks (parts and labor), it was actually less than I expected after hearing other stories. The best part? The car's running perfectly now. No more jerking during acceleration, and that annoying ABS light is finally off. Such a relief after dealing with this for weeks. The mechanic also gave the whole system a good check and said everything else looks solid, so hopefully won't have any more surprises. Really appreciate all the advice, helped me avoid getting ripped off and know exactly what to expect. Time to enjoy driving again without worrying about every little bump and noise!
