Audi UK are useless! they may as well pack up and go home! they have no influence over the dealers at all! none! I bought a 2015 A3 from Audi Tyneside and realized there was a hum from behind the dashboard after 1000rpm. Audi tyneside changed the timing belt but the noise was still there! so guess what they labeled it as a characteristic of the car. absolute rubbish. Audi uk get involved, guess what? after 3 months they close the case stating there was no mechanical issue...3 months! So buy from Audi at your own risk but beware if you have to have them fix your car because they couldn't care less once they have your hard earned cash and anything that is not blatantly apparent to them is disregarded as a characteristic. never again
