BMW X2 Sensor Failure Disables Multiple Auto Features

Had a similar issue with my 2017 BMW X1 last year. The symptoms started the same way, all sensors going haywire at once. The root cause was bubbles forming under the gel pad where the rain-light sensor sits on the windshield. The sensor itself was fine, but the separation between the gel pad and glass caused incorrect readings. Took it to the garage and they had to remove the sensor unit, clean the old gel pad completely, and install a new one with proper adhesive. It wasn't a complex fix, but it required specific knowledge about the sensor unit placement. The repair wasn't particularly serious, just needed precise work. Everything went back to normal after the fix, rain sensors, auto lights, and all dashboard functions working perfectly. If you're not comfortable with your current mechanic, I'd suggest finding one who specializes in BMW electronics. This isn't something you want a general mechanic experimenting with.

Thanks for sharing your experience! That's really helpful to know it was just the gel pad issue. I'll definitely look for a BMW specialist then. Quick question, do you remember roughly how much you paid for the fix? Also, has everything stayed working properly since the repair? Just want to make sure it's a long-term solution before I commit to getting it done.

Hey there! Just wanted to follow up about the repair costs since you asked. I paid exactly 62 € for the complete fix of the gel pad issue, and I'm happy to report that it was totally worth it. The rain-light sensor has been working perfectly since the repair, no more glitches with the automatic functions at all. It's been smooth sailing since then, all the sensors, lights, and dashboard displays are functioning just like they should. Looking back, I'm really glad I went to a specialist for this. While it might seem like a simple fix, having someone who knows these BMW systems inside and out made all the difference. I've had zero issues since the repair, so I'd say it's definitely a long-term solution. My auto wipers kick in exactly when they should, and the headlights are working like clockwork. You won't regret getting it sorted properly by a BMW specialist.

Thanks a ton for all the details! I actually took your advice and got it fixed last week at a BMW specialist. The whole experience was totally different from my last mechanic visit. You were spot on, it was the gel pad issue, and they fixed it for about 70 € which wasn't bad at all. The funny part was watching the mechanic work. He knew exactly what he was doing and fixed it in less than an hour. No more going back and forth trying different solutions like my last mechanic did. All my automatic functions are back to normal now, the rain sensors, headlights, everything's working perfectly. Really appreciate you sharing your experience. It saved me from spending way more time and money at my old mechanic who probably would've just kept guessing at the problem. Sometimes it really pays to get advice from someone who's been through the same thing!
