Audi S4 Quattro Avant V8

[Rosanne]

I've just bought one of the above. All the stamps are in the service book but it came with no bills or receipts.
The car couldn't be better other than an 84,000 mileage reading ( ( which was common on cars of this year 2006 ),
I'm concerned about the need for a cam belt change since probably the year and mileage may require one ? Is that right ?
Also, does the engine have to come out for a belt change ?
