Hi Colin,
I have a Q3 and thought I would have a go at fitting genuine mud flaps to it myself but it looked like a mammoth job, unless you have the car up on a ramp. I then decided to ask around for a price to fit only. First port of call was Audi Leicester where I purchased the car from and they came back with a price of £396, I had to look twice at the quote as I couldn't believe it. I then asked the next nearest Audi dealership to me which is in Northampton and they quoted £62.40 so guess what, they got the job and it took them less than 1/2 an hour. When I can figure out how to reduce the size of the photos I will post them on the forum.
