VXOC Astra-J/GTC

I own a 63 plate 2.0cdti. When is the official timing belt kit change interval? I think it's 6 years or 100k. Im now on 56k. Also realise I should change the waterpump too.
Cheers.

you are correct, 6 years or 100k, whichever comes sooner

Is the water pump driven by the cambelt on these engines? I know that some Vauxhall engines do, some don't. Would be interested to know as I also have a 2.0 CDTi.
