Hi all, So, roof has been working perfectly since I bought my A4 Cabriolet (2003) 18 months ago. It decides today to only open halfway and freeze, it won't go anywhere. I've read the manual to find where the manual override key is, only to discover that it's not there (I didn't think of checking when I bought the car). Does anyone know where I can buy a replacement one from urgently?!?! Thanks in advance. Or, if you're in the Sutton, Surrey area, would you mind letting me use it for 15 mins?!
