I was stripping down the mk3 today and found this behind the front wing by the A post/sill area. Got about 1 kilo of crap out of it.
yep well know dirt trap for the mk 3 is this area, mine was sooooo compact it was like it was part of the car hahah, im lucky mine had no rust but a friends car was bad in this area once we removed all the muck...
