BMW X7 Top Sensor Malfunction Halts Convertible Operation

Had a similar issue on my 2020 BMW X5. The convertible top would freeze halfway, with the same warning lights you're describing. Initially thought it was the motor, but turned out to be a loose connection in the wiring harness near the control module. Took it to my mechanic last month, they found corroded pins in one of the main connectors and some damaged wiring insulation. Not a major mechanical problem, but definitely needed professional attention since it's connected to the car's electronics. They had to replace the wiring harness section and recalibrate the top system. The repair wasn't particularly complex but required specific diagnostic tools to properly identify the fault points. Total repair time was about 4 hours. Since then, the top's been working perfectly, no more unusual stops or warning lights. Just a heads up, you'll want a shop that's familiar with BMW electronics, as these systems are pretty sophisticated. Your case might be different, but worth checking the connections first before assuming it's a sensor issue.

Thanks for sharing your experience! Sounds similar to my situation. It's good to know it might just be a wiring issue rather than something more serious. Would you mind telling me how much the repair ended up costing you? Also, curious if you've had any other problems with the top since getting it fixed? Been hesitant to take mine in without having a better idea of what I'm in for cost-wise.

Hey there! Just wanted to follow up, took my X5 to the mechanic and it turned out I was spot on about the issue. They found and fixed a faulty convertible top hall sensor that was causing all the trouble. The repair bill came to 95 €, mostly labor costs for fixing a bad cable connection. Pretty reasonable, if you ask me! Since getting it fixed, the convertible top's been working like a charm, smooth operation every time with no warning lights or problems. Really glad I didn't put off getting it checked out. Honestly, it was a much simpler fix than I initially feared. You know how these things go, sometimes what seems like a major headache turns out to be something pretty straightforward. My advice would be to get it looked at sooner rather than later. A small issue can turn into a bigger (and more expensive) problem if left unchecked. Let me know if you want any other details about the repair process!

Thanks for the detailed update! Really relieved to hear your repair was straightforward and affordable. Actually, I bit the bullet and took mine in yesterday. Funny enough, it was also a wiring issue, the mechanic found some damaged cables near the control module that were causing the sensor to act up. Total cost was higher than yours, around 150 for parts and labor, but still way better than I was expecting. They had it fixed in about 3 hours, and I'm happy to report the top's working perfectly now. No more strange noises or warning lights. My previous mechanic would've probably charged double and taken days to fix it. Glad I asked for advice here first, saved me from another frustrating repair experience. Really appreciate you sharing your story, it gave me the confidence to get it sorted before it turned into a bigger problem.
