Hi all, just a little update, when i broke down, i was in a queue of traffic waiting for my turn at a busy cross junction, my car was such a nuicanse to other motorists that HGV's trying to go around me ended up head to head with HGV's coming in the opposite direction so i was out of the car trying to help traffic flow whilst waiting on the AA. A Mechanic from a nearby garage was cought up in that traffic jam so he told me he'd be back with a Booster Pak to get me out of harms way. He returned 10 mins later and go me up and running enough to drive the car around the corner to his workshop with the bonnet in the air. He already knew it was the alternator but hooked up his Diagnostic tool anyway and confirmed it. Funny thing is, he previously owned a 2018 A7 with the same 55TFSI engine as my A6 and he also had to swap out his Alternator in that so he was familiar with the issue at hand. When the AA turned up, it was a diagnostics van rather than a recovery truck so the AA chap they took a quick look and affirmed that it's most likely the Alternator.
As i knew that i didn't have any warranty left on the car and that it was going to be ny impossible to get Audi to fix it, i kind of made the premature decision to leave my car with that indenpendant garge and allow them to get me a new alternator and replace it, they quoted me 1250 inc VAT for the Alternator and 350 labour. He said he wasn't making anything on the Alternator so he's done me a favour there, he was going to source and original Alternator from TPS or something like that?
After signing up to this forum today and getting advice from your goodselves i realised that i might just be able to get Audi to foot the bill so i rushed down to the garage to get them to hold off but they had already got to work on the car, i think they removed the front bumper to get to the alternator and they advised that they'll have the new alternator by tomorrow so i didn't think it was right to stop them at that point and i've let them crack on with it, at least i'll have the car back by Wednesday if the part arrives tomorrow.
sorry for wasting everyone's time, i did however email the DVSA contact that was shared by @Mark2 just so they can add it the list of complaints they're compliling.
Cheers all
Nik
