Hi, everybody! Cabrioverdeck opens (since spring) in turn (so 20x jerking), especially at my start of the day (even at midday, so not temperature-dependent!). Close is perfect! From the 2nd direct opening the function is perfect. If the vehicle stands several hours in the middle of the day, it just jerks 2 to 4 times, after 8 hours a little more. What can this be? Vehicle: Sebring Cabrio 2.7, year of construction: 2006. Thank you for your help!
