Funnily enough, I have just spent an hour trawling through ETKA looking at something very similar!
I'm trying to find replacement rear springs for my 2000 S3, the only exact matches (with five blue paint blobs) are the TT quattro (to 2002) and a golf sedan (2000) model type "PR-1JV" if that means anything to anyone?
The spring shortly after went to purple blobs, quite what the difference is I have no idea? The TQS will be different again....
