BMW 2 Series Multiple Sensor Failures, Help Needed!

Hey there! I have some experience working on cars and had a similar issue with my 2020 BMW 3 Series. The symptoms you're describing sound exactly like what I dealt with last year. After seeing those bubbles forming under the gel pad near the rain-light sensor, several functions went haywire. Took it to my regular workshop, and they diagnosed it as moisture damage affecting the sensor pad. They replaced the gel pad and recalibrated the sensor, cost me around 62 Euro and fixed all those weird issues. Everything went back to normal after that. Before I share more specific details about the fix, could you share: Is your car still under warranty? Are you seeing any bubbles or discoloration near the sensor area? When did these issues start showing up? This could help narrow down if we're dealing with the same problem.

Thanks for sharing your experience! My car just rolled over 190679 KM and had its last service two months ago. I am seeing those exact same symptoms, bubbles under the gel pad and everything. Unfortunately, my warranty expired recently. The issues started about a week ago, right after we had some heavy rainfall. Good to know it might be a relatively simple fix with the sensor pad replacement. I'll get it checked out at the workshop this week. Thanks for the heads up about the potential cost too, that's way better than what I was worried it might be!

Hey again! Yeah, those symptoms after heavy rain definitely confirm what I suspected. When it happened to my BMW 3, it was also right after some serious downpours. The timing of your issues matches perfectly with what I experienced. Since you mentioned seeing the bubbles under the gel pad, I'm even more convinced it's the same problem I had. Just a heads up, make sure your workshop uses the genuine BMW gel pad for replacement. My mechanic initially tried using a generic one, and it didn't work properly. Had to go back and get the original BMW part installed. The good news is that even though you're out of warranty, it's a pretty straightforward fix. The whole process took about an hour at my workshop. Just remembered, they also had to do a quick system reset after installing the new pad to get everything working properly again. If you're interested, I can share my mechanic's exact process for fixing it. It might help you know what to expect when you take it in. The most important thing is getting it fixed soon because moisture can eventually cause bigger problems if left unchecked. Let me know how it goes after your workshop visit!

Thanks so much for all the detailed information! This is super helpful, especially the tip about making sure they use a genuine BMW gel pad. I'd definitely appreciate knowing more about your mechanic's process, it'll help me make sure they're doing everything right when I take it in. I've actually already booked an appointment for tomorrow morning since, like you mentioned, I don't want to risk any bigger issues from leaving it too long. It's really reassuring to know this is a known issue with a straightforward fix. I was worried I'd be looking at some major electrical problem! I'll update you after they've had a look at it. Really appreciate you taking the time to share your experience!
