Hi there. I'm more of a follower than a poster, due to my insufficent knowledge on cars however i'm in a little dilemma and need some advice on what to do, how to go about it and maybe even what to say! I moved from a fautless albeit petrol drinking 8L Audi A3 1.6 to a B7 Audi A4 S Line Avant. Engine being the 2.0 TDI, code BLB. I bought the car on the 8th of June, and as of today, the 12th of June the car has a very LOUD grinding noise coming from the engine. This i presume is the oil pump chain on its way out or already broken. The RAC patrolman, ex Audi Service Technician said its either the chain or the DMF but to ask Audi for a goodwill contribution towards the costs of repair. I bought the car for £6,500 from a Trader. The mileage is 135,500 however the condition of the car is absolutley perfect. Where do i stand as to taking on the trader for the cost of the repair/refund of the vehicle? I phoned the trader and he said it was wear and chain and isn't covered but to let him know of the costs of repair from Audi on monday when it goes it. Is he obliged by law to pay for the costs of repair or give me a refund? The car has full audi service history except the last service, which was done by a specialist audi garage. Financially, I'm only 19 and i work part time. Saved up for the car and the insurance, but not for any repairs already! Legally where do i stand guys and girls? Where do i go from here? Do i take it to Audi, get a estimate, phone the trader and ask him to pay for the repairs or give me a refund? If he says no?? Thanks for any replies given. Much appreciated!!
