Wow that was a good solution do you have a picture of foam material you have use?I had the same problem on my 2005 T1, and I have the same problem on my 2009 T2. I have read, researched, and tried everything that was suggested without any success. In the end I just bought a 1 cm wide length of foam equal to the length of the upper vent and laid it in nice and tight. Problem solved.
