Look above to the scan by BingoMighty. If the PR code is the same as that shown on page 1 of your owners manual (which for a 2020 q7 it should be), then wave it in the dealer's face ! Which dealer?

Well done for pursuing. It will probably take another voice to support your concerns with the DVSA follow up in order to get a favourable response. Safety-related recalls normally require evidence of accidents or statements of failure where accidents were narrowly avoided. Lawyers won't be interested unless there is a claim or enough weight of claims to be made, and Audi will be about £ damage limitation. Is it worth contacting someone like the AA or RAC or some other lobbyist ? Maybe not. I suppose it could be argued that if Audi USA has a recall, it could either be for a safety or environmental (likely) reason. If Audi UK is using the global 7 year warranty claim path now without recall, they have clearly taken a commercial view rather that it is not a safety issue, and would surely have to share this with DVSA ?

No fault found with mine at service, despite a couple of yellow battery warnings last week and some buzzing noises after start up. New battery fitted by Audi less than a year ago. Have agreed for it to go back to have it charged / checked overnight in several weeks when a loan car is available. Fingers crossed - it has lasted nearly a year.

I just wondered if it needed to fail first ? When I bought the car a year ago it was back within a week for a new battery because of yellow low battery warnings. They checked the BSG, and it's been all fine until a year later when I've had a couple of loud buzzes not long after starting, one low battery warning - 'charge when driving', and I'm 90% sure that the stop start was greyed out after driving once ( I always turn it off).

Does the car have to fail / be recovered before they cover the BSG under the 7 year warranty ? Mine is due a service and has had a couple of symptoms, but is still running ok ...I I've always switched off start stop and disabled coasting.
