2 questions - Cambelt replacemment and Service Indicator question

[Smudge973]

Hello.
Audi A4 2009 2.0 TDI Multitronic.

Can anyone please confirm the mileage at which point the above mentioned Cambelt is due replacement replacing?
The service book quotes 114k miles, !?

Is this correct or am I missing something.

I also seem to think it should be 72k miles?

Also - The car has been for a service today and the service indicator reads:

Oli Service 18700 miles or 730 days
Inspection Service 11800 or 730 days

is the Inspection service mileage correct - Should this be 18700 also ?

Thanks
