Looks like I have to either call BMW support or visit my dealer.
Let us know how you go with yours.
In my case I could not initialize the sunroof. After 15-20 secs of pressing the tilt button, all I could hear was the clicking of a relay switch. This is the same problem I had with the first failure of the sunroof.
At the dealer, the mechanics pulled the roof centre console and the FZD module contained within. They then did a manual reset, and were then able to initialise the sunroof mechanism.
The sunroof is working properly now, but I’m concerned that it will become faulty again. This is because the “fix” is the same as the one the dealer did 9 months ago. To me, this is not good enough.
I see this as a temporary fix and have asked the dealer to contact BMW for a permanent fix. My suspicion is that the FZD is dodgy and needs to be replaced. My worry is that the problem reoccurs when I’m 100 km from home on a wet winter day.
As this sunroof problem is a known issue worldwide, I would like BMW to find a permanent solution.
