BMW 4 Door Sensors Causing Central Lock System Chaos

Hi there! I have some experience with cars and went through something very similar with my 2017 BMW 3 diesel last year. The symptoms you're describing sound exactly like what I dealt with. Had it checked at my workshop where they found a faulty cable connection to one of the door sensors. The wiring was damaged, causing those unusual door status messages and messing with the central locking system. Got it fixed for about 95 Euro, they basically had to repair the connection and recalibrate the system. Can you tell me which door is giving you the most trouble? Also, does it happen more often when it's cold or wet outside? This info could help confirm if you're dealing with the same issue. I know how annoying these electrical gremlins can be. Really hope this helps! Let me know if you need any other details.

Thanks for sharing your experience! My car just had its service at 56020 KM, and I'm getting these errors mainly from the front passenger door. It's actually happening regardless of the weather, which is what makes it extra frustrating. The issue seems unusual, sometimes it works perfectly fine for a few days, then starts acting up again. After reading your reply, I'm more convinced it could be a wiring issue. The price you mentioned for the fix sounds reasonable too. Did you notice any other electrical quirks before getting it fixed? Just wondering if I should expect other symptoms to pop up while I wait for my workshop appointment. Thanks for the help!

Hey again! Yeah, I totally get your frustration with those unusual issues, they can really drive you crazy! Actually, before I got mine fixed, I did notice a few other quirky things happening. The window controls on that same door started acting a bit weird sometimes, and occasionally the mirror adjustment would stop working. These were really intermittent though, just like your situation. Since you mentioned it happens regardless of weather and your mileage is pretty similar to what mine was when the problem started (I was at around 52000 KM), it really does sound like the same wiring problem I had. The randomness of it working fine for a few days and then acting up again was exactly what I experienced too. Just a heads up, when I finally took it in, they found the wiring insulation had worn down a bit where the cables flex between the door and the frame. It wasn't completely obvious from the outside, but that constant opening and closing had taken its toll. If I were you, I'd definitely get it checked soon. These things tend to get worse over time, and you don't want to end up in a situation where you can't lock your car at all. The fix wasn't too complicated in my case, and it's been working perfectly since then.

I'd follow up with: Thanks for all that detailed information! It's really helpful to hear from someone who's been through the exact same thing. Those extra symptoms you mentioned with the windows and mirrors are actually starting to make sense now, I've noticed my passenger side mirror acting a bit strange lately but didn't connect the dots until you mentioned it. I've already called my workshop and got an appointment scheduled for next week. Knowing about the possible worn insulation definitely gives me something specific to mention to the mechanics. Really hoping it'll be a straightforward fix like yours was. Really appreciate you taking the time to share your experience. It's always less stressful dealing with car issues when you have an idea of what you're up against. I'll update this thread once I get it sorted in case anyone else runs into the same problem! Thanks again for all your help!
