I bought my 2011 plate Audi A1 March 2014 from Volkswagen Swansea. Since purchasing the car any problems or any work done has always been carried out by them.

Last week, the turbo seals and DPF blew on the car resulting in £2,850 worth of damage according to Audi. The reason behind the damage was an oil overfill, according to Audi diagnosis. Reading up on this, it's sounds about right with the damage that has occurred, however Audi and VW have both denied any oil fill whatsoever. They have said that if they had put any oil in for any reason what so ever it would have been logged with them, and since buying the car I have NEVER put any oil in, as I have never needed to, so it is impossible for me to have overfilled it. Surely if the car needed oil it would of come up on the dashboard with it being a fairly new car? The only people to have been under the bonnet of my car is the Sinclair Group itself so if neither of us have put any oil in then it is impossible to be down to an oil overfill surely?

Could it be a wrong diagnosis? Could it be down to something else or even a manufacturers fault? Or if it is due to too much oil how can I prove they have over filled if apparently they have no records of oil being added? I understand it my word against theirs but I know I am not at fault and don't think it's fair I have to pay almost £3,000 for something I haven't done? Any advice or solutions would be thoroughly appreciated!
