After having a look on a thread or two I ordered mudflaps from Skoda parts and I got stuck into it this morning, fronts fitted like a dream, good job, but the rears don't seem to fit the profile of the bumper? Anyone know why this would happen? Does the MK3.5 VRS rear bumper still follow the MK3 profile

I think you needed face-lift model, I would go back to the dealer.

I've got mud flaps on my vrs estate, but I've a mk3. Not sure if there are different ones for the mk3.5

5E0075101A appear to be the facelift rears
