A4 cabriolet B6 1.8T door seal
 

Hi Guys

I have water getting into the sill on the passenger side and also noticed it dripping in from the join between the front of the roof and the top of the windscreen. I suspect its the door seal.

Anybody know where I can get a replacement from that wont be Audi main dealer prices? Audi want £170 for the seal which is ridiculous.

Or if its not the seal anybody have a clue as to what else could be letting the water in?

Thanks
Tony
