I had same problem - Intermittent fault with soft top - Audi said I would have to have diagnostic test (£140) which would then decide if it was warranty claim or not - if not I'd have to pay for "Test" and any other remedial work. If warranty company decided it was covered (??) then I would get the work done under warranty plus the £140 refunded. Sounds VERY dubious and not worth the paper it's written on - I'm sure they would decide it wasn't covered....
