BMW iX1 Multiple System Failures & Cruise Control Dead

Hey there! I had a similar situation with my 2019 BMW iX3 last year. Multiple warning lights came on at once, exactly like yours, including the dead cruise control and unresponsive steering wheel controls. Turned out to be a faulty steering wheel control module and damaged wiring harness connection. The main issue was corrosion in the connector pins of the steering angle sensor, which caused communication problems across multiple systems. Since these systems are interconnected in electric BMWs, one bad connection can trigger multiple warnings. It wasn't a major mechanical problem, but definitely needed professional attention. The repair involved replacing the control module and cleaning/repairing the wiring connections. The warning lights cleared up immediately after the fix, and everything went back to normal. I'd suggest getting it checked at a certified BMW service center, they have the right diagnostic tools for these electric models. These symptoms are pretty specific and match what I experienced, so it might save you some diagnostic time to mention the steering wheel control module specifically. Good luck with the repair!

Thanks for sharing your experience! That sounds exactly like what I'm dealing with. Really helpful to know about the steering wheel control module, I'll definitely mention that when I take it in. Quick question, do you remember roughly how much you ended up paying for the whole repair? Also, has everything been working properly since then, or have you had any other electrical gremlins pop up?

Hey again! Happy to give you an update! I mentioned earlier about having similar issues with my iX3, and I can now tell you it was definitely worth getting it fixed properly. My total bill came to 95 €, which was basically for fixing a faulty cable connection in the control module. Much cheaper than I initially feared! The best part? Since the repair, my cruise control and everything else has been working perfectly, no more warning lights or issues whatsoever. It's been such a relief, and honestly, it was a pretty straightforward fix once they identified the exact problem. To answer your question about other electrical issues, nope, haven't had a single problem since. The car's been running like a dream. It really was just that one dodgy connection causing all the drama. You know how these modern cars are, one small electrical gremlin can make it seem like everything's going wrong at once! Hope this helps give you a better idea of what you might be looking at cost-wise. Let us know how you get on with yours!

Thanks so much for all the detail! I actually just got back from the mechanic today. You were spot on about the control module, that's exactly what it was! Mine ended up being a bit more expensive since they had to replace the entire module rather than just fix the connection, but I'm just glad it's sorted now. The funny thing was, while I was there, they plugged in their diagnostic tool and the dashboard lit up even more before everything finally went dark and reset. Nearly had a heart attack, but the mechanic assured me it was normal during the repair process. The car's running perfectly now, cruise control, steering wheel buttons, everything's back to normal. All those warning lights are finally gone, and it feels like I got my car back. Such a relief it wasn't anything more serious! Thanks again for sharing your experience, it really helped me feel more confident about what needed to be done. Would have been much more nervous going in without knowing what to expect.
