Hi there,
Another victim of the Audi Mild Hybrid death trap. I have a 2021 Audi RS6 3 months outside manufactuer warranty. The usual process happened: Dash black out, gear dis-engage, engine off, no power steering then coasted into a safe place to park the car up (Luckly). Recovered the car to the nearest Audi dealership and they have tested the car and confirmed the alternator is packed up.
From reading here/ other forums I told them about the Audi 7 year drivetrain warranty, but they came back saying the RS6 is not covered under that and only the "diesel" cars are covered not petrol. Very strange. My local Audi dealer is fighting my corner with Audi UK currently.
If anyone with an RS6 outside its manufacture warranty in the UK and successfully had a failed alternator replaced under the "Extended 7 Year drivetrain warranty" please share more info.
