No they wont extend this in the UK... I have been to hell and back with Audi UK and Audi Germany... it is up to Audi UK at their discretion if they want to offer such a gesture as other countries do but Audi UK outright refuse... I don't see why UK owners should be any different... may be a class action law suit would give us the rights we so deserve?!
Other countries also offer good will on the following parts (10 years, 100,000 miles): high pressure fuel pump, pcv and there was one more thing... in my other thread.
The best Audi could possibly do is... if you have been a loyal customer and maintained your vehicle through an Audi main dealer... then there is a possibility for them to consider a contribution toward the repair costs... but again this is entirely at their discretion.
