STOP DOING THAT.Hi, i just bought a 2014 P85d and I have the same issue with the sunroof where it gets stuck open and makes an insanely loud clicking noise when trying to open. It looks like it opens on an angle and will never open fully. Takes a ton of clicks on the close button to actually get it to close again. OP how much did you end up spending? Are there local shops around the Wisconsin area that will fix this? It looks like they have to cut the whole thing out in order to replace it...
That is how I cracked my hinges, because glass got stucked and they I just continue to press open, open, open...until the bitter end
Did not spend nothing yet as I will try to find an alternate solution, as tesla service quoted me 2500 euros.
will keep you posted.
But I would suggest you to drive to the tesla service and ask them to take a look, maybe all it takes is a bit of new lubricate and it will work just fine. And perhaps some recalibration.
