2006 RS4 Cabriolet (just purchased) - was trying to find the cause of a serious leak that was flooding under the drivers seat (found it and not happy) anyway I came across a thin plastic (black) bag full of silencing foam and sealed with a hog clip stuffed in the hole in front of the front seat belt. The bag is about 20 cm long and 8 cm wide.
No idea what it is for and was almost certainly not in my previous 2003 2.4 a4 cab. Does not look like Audi quality
Thoughts - was it installed by a garage to stop a rattle or do others have this bag of foam?
