Since this afternoon the opening of the roof doesn’t work any more. This morning still nice open driving, then roofing and working. After 8 hours of service the nasty surprise: the windows go down, the Finns go up and then nothing does itself anymore, just a whirring but no more roof movement. So again. 3-4 times repeats, but always the same. Luggage compartment up and down, nothing. Does anyone have any idea what it could be or what one could try without Wekstatt first? (6 50ix Bj 07/13)
