Hi everybody! My apologies for not writing in German, hope you guys can help me in English? I'm a new A2 owner and I'm having some trouble with my Open Sky System. Tha car is too old to be repared under the Audi guarantee, so I will have to fix it in some other way. Check out this video: The system needs some time to get into action after I push the open/close button. There's a loud cracking noise once the 2nd window gets picked up. And, I'm also not sure about the window opening to it's maximum. I'm seeing photo's on the internet with OSS opened even further than the middle door bar. What do you think? Can you give me some advice? Thanks in advance, and again sorry for my English....
