Have not gotten around to replacing microswitches in kinematics boxes yet.

Noticed new symptoms that are happening.
Been driving in the city for the past week or so and during that time i havent had any boot open warnings any more. Not bumpy enough i guess...
BUT...

About half the time i drop the roof, after the rear glass has folded on top of roof and trunk lid opens backwards to recieve the roof package, about when trunklid is half way vertical or almost vertical i hear trunk lid softclose operating and pulling trunklid to close. Same softclose sound when softclose is pulling the trunk shut when you close trunk normally..

Can this also be caused by the microswitches at the kinematics box?

I have started to think that issue is maybe in the trunk lid itself. Read on some other forum where multiple owners had wires break in the trunklid near some sort of connector and that caused softclose to go nuts or not work at all.

thread i read:

Any thoughts?
