Hi,
just to add my 2pence worth in.
Audi were reluctant to send the tyre to Dunlop, as they said last time it took months for a reply and then dunlop said it wasn't defective.

The dealership complied and the tyre has been sent - no idea on how long this will be.
I have now put two Continentals on the front -
