Just to update, rang Bath Audi as we'd just bought another car from them and had a great service experience, the chap in parts had the required part numbers for me in under 2 minutes.. I then called back the useless fool at Bristol to order the parts required, he actually seemed annoyed that i'd managed to find the part numbers.. I'd have stuck with Bath but it's a pain in the backside to get there from where i am, especially since it moved..
Re Bristol Audi in general, i've had 7 Audis now.. I live 15 minutes away from this dealer, and not one has come from them, even though on all 7 occasions i've given them another chance to try and treat me with a scrap of respect.. Failed every time..
Don't even get me started on the service department..
