BMW 320d E91 Sunroof opening by itself, FZD error A671. Fault finding and repair. HD

Consider to support my channel and all the hard work put into it at http://www.patreon.com/LMAutoRepairs Thank you Hi This car came to me with a few issues related to the sunroof. Although I have not showed it, the roof would stop closed slightly dropped, not even with the rest of the car roof... Anyway, the main complaint was that the roof would open randomly on its own... while driving (Which happened to me...), or few minutes after being parked... I had a few drawbacks on this one, but got there in the end! Follow me on this video to find out the problem and how to have it repaired. Hope you enjoy the video. Any questions or comments, please put them below. Like always, thank you for watching!
