if you fit a decent quality belt and ensure it's tensioned correctly it wont make odd noises, it's not quantum physics to cure it so beware and make sure it's actually the belts making the noises

broken windscreen washers are also not quantum physics to change

elps if you put where ur from in yer profile

Could be the intercooler pipes have a hole or split in them.

300 Tdi belts are renowned for squeaking/whistling. Talcum powder gives a temporary cure. Land Rover produced an alternative "Quiet" belt, but didn't recommend it for off road use, I asume it was more prone to slipping if it got wet.

If its a squeek were talking about then I would agree its just the 300tdi belt squeek - its just an identification marker... But if it is a squeek and not a whistle check the pipes.
