I noticed what I think is a design fault.
at work there we have three of us with VW Golf Mk7. We have the same issue.
when it's wet it seems that water gathers on the top of the rear bumper - it often has dirt in it - and when it dries it leaves a dirty mark.
does anyone have an answer as to how to solve this? It's annoying - I washed and waxed car - then it rained - and within a couple of hours the dirty mark was back!
