Should I change the cam belts on my Audi A4?

I recently bought a Audi A4 S line TDI 2L 148bhp, reg in December 2008. It now has 80,000 miles. I'm having it serviced soon but wonder if I need to change any of the belts? Its last service was at 60,000 miles. Any advice you can give me would be much appreciated!

At this mileage good to change timing belt, tensioner, all small timing belt pulleys and the water pump.
