Hi all, I've got the problem with my S3 that there is a "whine" at higher RPM and in gear changes, most pronounced between 4th and 5th. After a lengthy battle with Audi they are saying the car needs a new DSG box at an estimated cost of £7-8k? They will not give me the exact gearbox fault as they wont strip it down. My car is under warranty with Inchcape Audi in Kent until Dec 2019 but they are refusing to carry out the works under this because i was 1,500miles over my allowed mileage at my gearbox oil change. This is due to when i called on April 10th last year to book in my service, the earliest appointment they could give me with a courtesy car(needed for work) was the 23rd of June. 10 weeks has a tendency to rack up mileage when my allowance is 20k miles per annum. Audi also failed to changed the Haldex oil and spark plugs on its service interval and carried out the works at a "good will" gesture at the following service. Seems annoying they hit me with liability for a 1,500 miles when they have missed by a whole interval. Anyway, enough ranting..... Have any of you had a similar fault, experience? I could really do with advice, i have no chance of magicking up the money so will have to stand the car, rent another and save. So far i have contacted mainline Audi customer service and spoken to a customer liaison officer who was less than helpful. Any advice is really appreciate.
