Hi All, I've just picked up a 2008 B8 3,0TDI Avant at a good price, so looking forward to some time on this forum. I know members such as Karl with the 380bhp+ 3.0TDI so know there's some good guys on here. So to start with.... I need to sort a water leak around the panoramic sunroof. The rear right seat is wet and headlining above. I believe I first need to check the front and rear drains? So peel back the rear wheel arch liner and access the rear drain from there? Any help appreciated - ive done a few searches and found various info, but was hoping this thread might end up as a useful one as I'll put all the info on here.
