Excellent!
Without the knowledge of the forum I think we would have all paid through the nose to have this work done. Don't think there can be many E89s left that haven't had at least one set of microswitches fail!

Thanks for the update gents, I am going to try doing mine also.

I have ordered the sensors from BMW, £19.90 each.

Any additional tips from having done the job yourselves?

My only question from the video is regarding marking the nuts - not having looked at the arm yet I assume the nut position can easily be changed hence why I need to mark the original position in the arm before removing?

Wish me luck

Very straightforward swapping over I found

The nut position can be changed on the bracket, and has play in it to allow alignment etc - i just marked round it with a paint pen so could it them all back exactly where they were - no issue with roof opening etc once back on.

Yeah paint pen did the trick for me. And I found mine were right at the far end of the bracket space and needed some pressure rather than just being where they sat naturally.

Thanks both, probably a stupid question but I'm in the middle of doing mine and can't unclip the microswitch connector - any tips?

All fixed!!

Thanks so much everyone, well chuffed

In the end it took me about 3 hours in total, but that is because I didn't know what I was doing and took more trim etc than I need to off.

In the end I couldn't disconnect that electrical connector so I just cut the cable off higher up and spliced on a new microswitch - then did that the other side in about 10 minutes and avoided needing to cut all the cable ties already in place.

Hoping that's fixed it permanently - no lights on so far and roof works perfectly again
