hmmm, it really seems to be a PITA, there is no obvious, cheap and easy solution.
I may just rub down and paint the old one, at least it will fit correctly, although me and a can of spray paint dont always work well together!
And another thing I have found is the strange part numbers that VW bombard you with, I must have seen 10 different part numbers for what looks the same part, which is whats confusing me. I just know im gonna end up buying the wrong part.
Sod it, im going to the scrappy today!
