Took mine to Preston Audi Friday, the Audi guy said its a common problem for A3/S3 on the roof guttering. Audi said they will let me know in the next few weeks.
AS3TOM; Which panels did they spray to sort out your car?
they sprayed the back rear quaters leading into the rails on top of the roof and they also sprayed the roof too!
letting you know in a few weeks...quite a while to wait that, i only waited 2 days to get the go ahead and then for the actual work to be done i had to wait about 3 or 4 weeks for it to get booked into the body shop!
