cam-belt

Hey y'all, Hope anyone/everyone reading this is well. I have my 52 plate 1.6FSI A2 with only 65K miles (genuine) to run around in. i had a service today - £480 for a larger service replacing brake discs and fan belt but i was also made aware that the Cam belt may need changing as hasnt so...

I believe my 04 TDi is due a cam belt and I understand that this could cost around £350 without the water pump. Has anyone done this themselves or are special tools/expertise required? I have done it on other cars but don't want to start something I can't finish. Cheers
