On a brighter note. Booked the car into AudiVolkswagen centre in Melksham for a 2 year service (23K on clock). Was quoted £160 for the service plus another £27 for a brake fluid change, and another £23 for tracking check (hit some nasty pot holes recently). They said they used Audi parts and therefore the warranty is not affected. See
http://www.audivwcentre.com/ As you can see, one is not paying for the plush premises of the main dealer who sold me the vehicle - they said it would cost £450-£500.
Incidently, the Westbury Oval VW dealer declined to service the vehicle as in their opinion it would affect the warranty.
