Ooops - Jaxonalden just pipped me.....But here goes anyway.
Sounds like you have had an intersting weekend....I hope the sanger didn't have a soft filling
The popping was the plastic ball joints on the control rods breaking off. The originals (white coloured) are weak & have been superceded by updated (red) ones.
I thinke there are a couple of "how to" install new ball joints if you use the search function.
June this year I was opening my roof, about halfway down I heard one pop (not two like you) and noticed the roof opening skewed over. I tried closing the roof with the dash switch but only one side closed - the drivers side (RHS here in Oz) just sat there.
Long story short, looked in the manual and it describes that to get the roof safely stowed, you have to prize off the ball joint on each side with the special tool in the toolkit.
The downside is that there is a possibility to damage the clamshell paintwork when popping off the ball joints as the clam is in tension - you really need 2 pairs of hands to do it safely I think. My wife wasn't up to having trapped pinkies so I rang the OPC and asked for guidance - they recommended 2 people to reinstall and re-align everything up.
But it was possible to drive the car (~75 miles to the OPC) if I wanted to for them to replace the ball joints/rods etc and to realign & tension the roof.
So I folded (call me weak, but possible repainting the clamshell + roof repairs = wifes skinned knuckles were staring me in the face) & took it to the OPC for the repairs.
I won't scare you with the bill because $$ costs in Australia are about 2 - 3 times what you guys pay....
But I will say that the car is a lot quieter at high speed since the roof was retensioned.
