Hello Adrian,
Forget about the USA - VAG treat their customers differently in this country!
Warranty on a 12 year old car? Forget about that too, although as I understand it, VAG were making some contribution on <10 year old vehicles will FSH until a couple of years ago, but not any more as I understand it.
Not that it matters, but you don’t tell us how long you’ve owned this car Adrian, and what level of servicing has it had throughout its life.
Re getting rid of it - I think I’ve already suggested what I would do if it were mine, but only you can counter or agree with that advice.
Be prepared that if you were to sell it, the trade are likely to know of the issue and will price it accordingly.
Kind regards,
Gareth.
