The VAG Germany official line is 10 years or 140k miles and VAG UK now follow this rather than lying and saying 5 years, they must have really felt the hit from losing that cash cow. Personally, I feel 10 years/140k is WAY too long, VAG may say 10 years/140k but if it failed 1 day outside the three year warranty at 30k miles, they would wash their hands of you. We have decided to settle on 6 years, 60k miles BUT tell customers the truth and let them make the choice.
