This may be a long shot...my A4 USP front passenger-side door blade developed a bulge and upon investigating it turns out that water had leaked inside the mounting behind the plastic and rusted part of it out, creating this problem.
I cleaned everything out and put the blade back together but while the cover is OK the mount behind it seems to be gone.
So if anybody has a front passenger side door blade, probably does not matter whether USP, S4-type, or regular? in any color please let me know -- I'm thinking I can use the mount from it and add my outer skin which is in good shape. Seems to be glued in.
Thank you
