BMW Error Messages Point to Emergency Call System

Hey there! I had a similar situation with my 2017 BMW 3 Series last winter. The error messages and warning lights kept popping up on both displays. After avoiding it for a week, the warnings became more frequent, so I had to get it checked. Turned out the SOS emergency call module had a faulty wiring connection. The cable harness was damaged, causing intermittent connectivity issues. It's not a major mechanical problem, but it needs fixing since it's a safety feature. Had it repaired at a BMW certified shop, they had to replace the wiring harness and reprogram the module. The whole thing took about 3 hours. Not a complicated fix, but definitely needed professional diagnostic equipment to properly identify and resolve the issue. Worth getting it checked soon, while it's not affecting your engine performance, you want your emergency call system working properly. Make sure to find a shop that specializes in BMW electronics. Best of luck with the repair.

Thanks for sharing your experience! It's really helpful to know it was the SOS module wiring in your case. Did you remember roughly how much the repair ended up costing you? Also, have you had any other warning messages pop up since they fixed it? Just want to make sure I'm ready for any potential follow-up issues when I take mine in.

Hey again! Just wanted to let you know that after getting my BMW fixed, everything's been running perfectly smooth, no more annoying warning lights at all! The mechanic found it was indeed a cable connection problem with the emergency call system, just like I suspected. The total bill came to 95 € for fixing the faulty connection, which honestly wasn't as bad as I'd feared. They had to repair some wiring and a plug that had come loose over time. The best part? It only took them about an hour to sort everything out. I'm really pleased to say I haven't seen a single warning message since then, it's been completely trouble-free. The SOS system is working exactly as it should now. Sometimes these BMW electronics can be a bit finicky, but once you get them properly sorted, they're usually good to go. If you're worried about potential follow-up issues, I can honestly say I haven't experienced any. Just make sure you go to someone who knows their way around BMW electrical systems, it makes all the difference! Let me know how it goes when you get yours checked out!

Thanks so much for your detailed response! I finally got around to taking my car in yesterday and wanted to share how it went. You were spot on about going to someone who knows BMW systems well. I found a specialized shop, and they diagnosed it was exactly what you mentioned, a wiring issue with the SOS module. The repair was actually pretty quick, only took them about 90 minutes. Cost me a bit more than yours though, around 150 €, but they also did a full system check while they were at it. The mechanic was really thorough and explained everything clearly, which was such a relief after my previous bad experience. Just drove it home, and all those annoying warning lights are finally gone! The dashboard is back to normal, and the nav screen is working perfectly. It's such a relief to have it sorted. Really appreciate everyone's advice, it definitely helped me feel more confident about getting it fixed. Think I've found my new go-to mechanic too. Sometimes these electrical issues can be pretty scary, but it turned out to be a relatively simple fix in the end!
