The beep noise and red flash to indicate that the roof is retracting in my copen is going off intermittently, with no apparent reason. Ive had it at the garage to check the electrical connections etc, and the roof has been lubricated and still works fine. No faults were identified and they can't work out why this is happening. Seems to have come on all of a sudden. Just wondering if anyone else has come across this problem, and has any idea how to sort it out? Any advice is appreciated. Thanks!
