Hi guys Before you start reading this bear in mind I am not hugely mechanically minded... Had the cambelt and waterpump done on my car a few months ago at one Audi Dealership. Now I have taken it to another (wasn't impressed with service at first place) for a small service... Whilst doin their usual inspection it was noticed that it was low on coolant, first Audi dealer would have been working right by where the coolant tank is situated. Anyway after a brief chat they agreed to rectify as the work was under warranty. Just had a call from them to say that whilst taking the waterpump out that they said a piece of the cam Tensioner had broken off and would therefore need replacing. Likelihood is it's the original part and the car now sits at 56k. I said to go ahead as I didn't have much choice as I can't drive a car without it. After I came off the phone I suddenly thought.... Either the first Audi missed it and didn't spot it's poor condition or because it's being messed around with a second time this has messed it up. In other words is it not Audi's place to replace under warranty as potentially it was their bad? They clearly aren't charging me the labour to replace but it's Â£100.10 Inc vat for the part.
