Hi all,
lately we have noted some type of liquid leaking from my old mans Passat CC doors.
it looks like its coming out of the door drains, but must splash or get flicked up on the side of the doors as its visible there and on door sills (1cm x 3cm area on outside of doors) at each drain
I have washed it off once or twice already but it keeps coming back. Any ideas? We could only think of it been added for salt protection?

Will take some photos if i remember

Cheers, Dylan
