I've just bought a Sportback BE and seeing the rubbish that's getting thrown up the side of the car, think it needs some mud flaps. I've seen a set from an Audi dealer on e-bay for £64 posted, but there seems to be differences in the ones you need. My car is a sportback s-line black edition. Can someone confirm if they are standard fit, or do I need to order specific ones. (If someone can point me towards any cheaper, I'd be grateful) Looking in the wheel arches, I'm assuming that it's just the two screws to hold each one on?
