Just noticed this today, after closing the sunroof, I hit the button again to close the shade. It closes fully and then opens again 1/2 way. It refuses to stay fully closed. I made sure the roof is fully closed properly and tried a few more times. It just goes back to a middle position?? I've fully opened both and tried over and over, no luck.

I've had that problem before. It was fixed by resetting the sunroof. Hold the 'tilt' button for 10-15sec and the sunroof will go through an opening and closing cycle. I learnt that from a YouTube video (albeit not in a G20 car).

This sounds all too familiar to my experience with my E46 and E90, which both had constant sunshade problems.

If I remember correctly, the problem was the shade has plastic clips and a rail in which they slide on. Over time the plastic clips break, get stuck in the rails, and when using the buttons to fully close the shade without holding the button, the shade would go a certain amount and then go back, as if some sensor had detected a fault.

Although, unlike you my shade would never fully close and then open back up, it would simply go 1/4 or half and then back. I wouldn't think a car that new would already have broken clips, so I would go to the dealer, as your still under warranty. Also try closing it by pushing the button, but not all the way (before it clicks). When I would close the sunroof I would have to do it in increments pushing and releasing the button every few seconds, see if that works.

Good luck!

This did the trick, good info, thanks!

My sunroof glass closes then re-opens halfway. I have to hold the button forward to close it. I'll try the reset.
