Ok here is the story. Audi a3 2.0 t FSI S-LINE QUATRO I sold my wife's car 2 weeks a go and there where no issues with it all . it was advertised with full audi service history , which in my honest opinion it has. We have had it serviced at Audi Manchester on the long life service indicator on all previous services, although as we where selling it soon we opted on the last service ( in April this year when the service indicator came up on the dis) To have the standard service as is was of course cheeper and did not want to spend the extra as it it would not make sense. I just wanted to continue the Audi full service history. Now some Two weeks later the person we sold the car to has contacted me saying there are problems with the turbo , which is honestly news to me. He is saying the following : he has spoken to Audi Manchester and they have advised him that haldexoil/filter was not done at the service. HE is saying that due to this the car does not have full audi service history , and now want's his money back. i have spoken to manchester audi and say that it is not part of the service but is an added cost option at the point of service say 40.000. The service book is stamped by Audi for every service and i of course advertised it with FASH. It is a bit weird that 2 weeks after sale there is a failed diverter valve on turbo , ( which has cost him £ 40.00 plus 2 hours labour ) And now wants to return the car to me , BUT the reason why is it does not have FASH. Sounds like he is having second thoughts and is trying anyway he can to return it. Surly if the service book is stamped and up to date by Audi that means FASH ? My receipt stated SOLD AS SEEN , i also put that there was NO known issues at time and date of sale, which is the truth. He is now threatening legal action. We sold the car in good faith and of course have spent the money on a new car , it is a total stress ! I would like clarification, i am right in saying it has FASH?
