I'm surprised you didn't experience the same phenomenon on all the
black vw trim.  I had a similiar problem due to the wax from car washes
and the wax when I waxed my car.
There is a product (about 5 - 7 $) in a can that is specifically made
to restore the black color to the plastic.
I works but must be applied periodically.
