Hi folks. I am presently getting the parts and tools together for a second cambelt change to my 2002 Allroad (first was done by Audi at 75K).
I will be changing 2 cam belts, 2 cambelt tensioners and a cam relay roller along with the water pump, thermostat and the 2 poly v-belts.
Given I will already be in there (and hope not to be there again for another 75K!), which (or all??) of the following should I also change:-

For the cam belt:
059 109 479 B Belt Tensioner Damper (quite pricey item!)

and for the Poly V-Belts:
059 903 341 A Relay Roller
059 903 341 Relay Roller (again quite pricey)
059 145 276 Relay Roller
059 260 523 B Tensioning Roller (again quite pricey)
059 145 284 B Damper

Again, thanks in advance for your advice.
