Volvo V70 drive belt and waterpump?

I have a June 2009 Volvo V70 2.0D. It has just done 103000 miles. At the next service I have been advised by the garage to have the drive belt changed and the waterpump. I know this is the case for VWG engines - but is this timing of the belt change correct (I have seen different mileage advice for this engine) and would it be good practice to replace the waterpump or leave it alone? I intend to keep the car as I do 20000 a year.
If it's done more than 100k miles then the timing belt together with tensioner and waterpump all need to be changed now, not later. Waterpumps can and do fail, throwing off belts and wrecking these engines.
