BMW 2 Series Electrical Gremlins Driving Owner Crazy

Hey there! I actually dealt with very similar issues with my 2017 BMW 3 Series diesel. Had the same unusual error messages and unresponsive control units. Last month at the garage, they diagnosed it as a faulty cable connection to the BUS system. The control unit wasn't communicating properly with other modules. The mechanic showed me that some cables had deteriorated insulation and were causing intermittent connection problems. It was quite a serious issue since it affected multiple systems. They had to replace the entire cable harness and reprogram the control unit. Took them about a day to fix it. Since then, my car has been running perfectly, no more unusual errors or system failures. Given your symptoms, it sounds very similar to what I experienced. I'd suggest getting it checked soon since these electrical issues can potentially affect safety systems.

Hey Dave! Thanks so much for sharing your experience. It's really helpful to know that fixing the cable harness and reprogramming sorted out these annoying issues. Would you mind telling me roughly how much you ended up paying for the whole repair? Also, just curious, have you had any other electrical problems since they fixed it?

Happy to help out! Glad I could share my experience with these pesky electrical gremlins. After getting it fixed last month, I haven't had a single error message or system glitch, it's running like a dream now. The total bill came to 155 € for fixing that faulty cable connection to the BUS system control unit. Honestly, I was relieved it wasn't more expensive, as I was worried it might be something major when all those unusual errors kept popping up. My mechanic explained that these sorts of connection issues can cause all kinds of weird symptoms because the different systems can't communicate properly with each other. But since they sorted out that cable connection, everything's been working perfectly, no more dashboard warning lights or unresponsive controls. If you're seeing the same symptoms, I'd definitely recommend getting it checked out sooner rather than later. These things tend to get worse if left alone, and you definitely don't want that with a newer car like yours.

Hey Dave! Just wanted to update you, I finally got my car checked out yesterday. You were spot on about the cable connection issue! The mechanic found similar problems with deteriorated cables in the BUS system. Had them replace the faulty parts and do a full system reset. The whole thing cost me about 180 €, a bit more than what you paid, but still not as bad as I feared. The best part? All those annoying error messages and glitches are completely gone now. The infotainment system is working perfectly, and no more unusual warning lights on the dash. Really appreciate you sharing your experience, it gave me the confidence to get it sorted instead of putting it off. The mechanic mentioned it was good I brought it in when I did, as these issues can get more complicated if left unchecked. Thanks again for your help! Mark
