Ah, just down the road then, my friend
I used Teesside Audi on the Preston Farm Estate. I timed my work with the cambelt as they need to take off some of the parts to change that. They were going to charge me £2100 but after negotiation got this down to £1850 (but this included the cambelt).
Got a nice A6 S-Line to drive while my car was in, just a pity I had to hand it back
