BMW 1 Series Multiple System Failures, Radar Issues?

Hey there! I've got some experience working on BMWs (some experience level). I had a similar issue with my 2013 BMW 3 series. Got those annoying warning lights and system failures too. Turned out the radar sensor was just dirty! My trusted mechanic cleaned it properly and recalibrated the system. Cost me around 45 Euro, which wasn't too bad considering I was worried it'd be something major. Could you share more details about when these warnings started appearing? Like, did it happen suddenly or gradually? Also, are you driving in any particular weather conditions? This info would help figure out if it's the same problem I had. The 1 series and 3 series share quite a few components, so it might be the same issue. Better get it checked soon though, these sensor problems can mess with your safety systems.

Thanks for sharing your experience! Mine started acting up about a week ago, right after my last service at 140705 KM. Initially, it was just occasional warnings, but now it's becoming more frequent, especially during highway driving. It's getting pretty annoying, and I'm a bit concerned about the safety systems going haywire. Thankfully, I've got an appointment with my mechanic next week. I'll definitely ask them to check if the sensor just needs a good cleaning like in your case. Really hope it's something that simple and won't break the bank!

Hey again! Thanks for the extra details about your situation. You know what's interesting, my issues also started showing up right after a service too, but mine was at around 132000 KM. Makes me wonder if something got knocked loose or misaligned during the service. The fact that it's happening more on highways really rings a bell with my experience. That's exactly how mine started, occasional warnings that got worse at higher speeds. In my case, the mechanic found that during the service, they'd used some cleaning product that left a residue on the radar sensor. Plus, all the highway driving had caused extra dirt to build up on it. Since you mentioned you're going to the mechanic next week, definitely ask them to check the service records. Sometimes these issues can be traced back to something simple that was overlooked during routine maintenance. When they fixed mine, they also updated the sensor's software while they were at it, might be worth asking about that too. Keep us posted on what they find! I'm really curious to know if it's the same issue I had. These BMWs can be tricky sometimes, but usually, it's nothing too serious when it comes to sensor stuff.

Thanks so much for the follow-up info! That's really interesting that your issues also started after a service. I'll definitely mention this to my mechanic and ask them to check if any cleaning products were used that might have affected the sensor. I hadn't even thought about software updates, that's a great suggestion! It's such a relief to hear that your problem wasn't anything major. I've been stressing about potential repair costs, but knowing that yours was just a cleaning issue gives me hope. Will definitely get them to look at the service records too, just in case something was overlooked. Really appreciate you taking the time to share all this detail about your experience. I'll update the thread once I get it sorted out, might help someone else with similar issues down the line.
