My audi A6 2019 50 TDI Mild Hybrid quattro C8 had an issue with its alternator. Milage is about 79000. I've had a mechanic provide me with the fault codes from their diagnostic checks. Please see below.

I have a diagnostics check booked with Audi on 7th January 2026 for £150. When does the 7 year warranty expire? I'm calling them daily to try and get an earlier date. But I think they've caught on and don't want to give me an earlier date. I've had the battery replaced via Halfords because I thought that was the problem. My issue happened in mid November 2025. Some audi agents who have checked my car REG, VIN have said that according to their own database there is no recall for my car's alternator or maybe the car. I don't know if they are just trying to put me off going to them.
A lot of Audi agents have told me that they can't confirm that my car's alternator is covered under the 7 warranty until I do a diagnostics check with them to pinpoint the problem. I assume that if it is then they have to refund me the £150.
I'm aware of this https://www.check-vehicle-recalls.service.gov.uk/recall-type/vehicle/make/AUDI/model/A6/year/2019/recalls
The cheapest quote I've got from a mechanic is £2200. I don't even wanna know what Audi will try and charge.
Can someone please help me fight this?
