Audi A3 Gearbox Mechatronic Unit Failure

I own a 2023 Audi A3 and I experienced a mechatronic transmission malfunction which caused the car to stop working and display different kinds of fault warnings. My vehicle’s warranty expired only about three months ago, yet this serious issue occurred shortly after, even though I paid more than ₺200,000 for this car. I know this is a common problem in many similar Audi vehicles, but it is never admitted as such. Previously, I also had a 2021 Audi A3 and experienced the same mechatronic problem with that car as well. In June 2025, I had to have it repaired in Antalya and paid ₺35,000 for that repair. Having the same serious fault in two different Audi A3 vehicles has completely shaken my trust in the brand. For the current problem, I went to Başaran Oto Fethiye for support, but instead of helping, they immediately claimed it was “user error” and stated that if they opened the transmission, they would definitely charge service fees because in their opinion it is “100 percent customer error”. They even suggested reasons like driving in rainy weather or on new asphalt, which I find unacceptable as an explanation for such a failure in a nearly new vehicle. At the service, I felt that they were only interested in taking money and not in solving the problem. They clearly told me that I could “call anyone I want” and that “no one can do anything to them”, which I found extremely rude and disrespectful. Because of this attitude, I decided to take my car back from Başaran Oto Fethiye and had it sent to Antalya by roadside assistance, where it is currently located. Due to this problem, I have already paid around ₺2,000 for roadside assistance and other related expenses. This experience has completely destroyed my trust in both Audi and Başaran Oto Fethiye. I have decided that this will be my last Audi, and my first priority now is to sell this car. I think being an authorized Audi service should mean more than just changing oil and air filters, and I believe Audi is losing customers in Turkey because of such service quality and recurring mechatronic issues. Even though I no longer expect any support from this service, I want it to be officially recorded how I was treated, that a known mechatronic problem is being pushed onto the customer as “user error”, and that I was left alone with an expensive and serious fault just a short time after the warranty expired. I am sharing my experience on all social platforms in Turkey so that other customers are informed about this situation.
