BMW iX1 Door Sensors Causing Frustrating Lock Issues

I had a similar problem with my 2019 BMW i3s last month. After multiple door sensor warnings and lock malfunctions, took it to the garage. Turned out the wiring harness in the driver's door had some damaged cables, and one connector was corroded. The problem wasn't just the sensor, moisture had gotten into the connection point and caused intermittent electrical failures. The repair wasn't too complex, but accessing the wiring required partial door panel removal. They had to replace the harness section and clean the connector pins. This wasn't a serious mechanical issue, but it needed proper attention since it affects safety systems. Definitely recommend getting it checked, these electrical gremlins can get worse over time. My issue started just like yours with unusual error messages and unreliable locking. The symptoms you're describing match exactly what I experienced before the repair. While you mentioned having reservations about your mechanic, this kind of electrical work needs someone who knows BMW's systems well. Worth finding a reputable shop that specializes in BMW EVs.

Thanks for sharing your experience! That actually sounds exactly like what I'm dealing with right now. The symptoms match up perfectly with what you described. You've convinced me to get it checked out sooner rather than later. Do you remember roughly how much you ended up paying for the repair? Also, has everything been working smoothly since they fixed it, or have you noticed any other quirks popping up?

Hey there! Happy to give you an update. After I got the car fixed, everything's been working perfectly, no more door sensor warnings or lock issues at all. The mechanic found it was indeed a faulty door contact signal caused by a damaged cable connection, just like I suspected. The total bill came to 95 € for fixing the cable and plug connection. Honestly, it was money well spent because those unusual warnings were driving me nuts! The repair was pretty straightforward once they identified the exact problem. My i3s has been running like a charm since then, no new quirks or issues to report. The auto-lock works perfectly now, and I haven't seen a single door error message on the display. It's such a relief not having to double-check if the doors are actually locked anymore. If you're still having those issues, I'd definitely recommend getting it sorted soon. These electrical problems can be annoying but they're usually pretty simple to fix once you get them to the right mechanic. Let me know how it goes when you get yours checked out!

Thanks so much for all the details! Just got back from getting my car checked out, and you were spot on. Had a totally different experience with a new mechanic this time. They found the same issue, damaged wiring in the door harness causing those annoying sensor problems. The repair cost was slightly higher than yours, but it was worth every penny. They did a thorough job explaining everything and even showed me the corroded parts they replaced. Took about three hours total, but now everything's working perfectly, no more unusual error messages or lock problems! Makes such a difference having a reliable mechanic who knows what they're doing. The guy even gave me some tips about preventing moisture buildup in the connections. Really glad I followed your advice and got it sorted quickly instead of waiting for it to get worse. My car feels like new again, and I can finally stop worrying about whether my doors are actually locked! Thanks again for pushing me to get it checked out. It's such a relief having this fixed properly.
