My 300tdi has started with a squeak yesterday and its driving me mad! Sounds like engine Bay Area so wd40 all drive belt area and still squeaks. It's only while driving
 
look for the penny trick thread, that should do the job!! it goes behind the auxiliary belt tensioner, worked for me!! good luck..

Must be wheels/transmission if as u say "It's only while driving".. Aux belt or any thing engine related would be all the time it's running.

boll++++ my tentioner was sha++ed and it only showed its self whilst under load
 
I had a similar problem on mine. It sounded like i had a canary under the bonnet. I replaced the bearing in the tensioner (easy job), tried the penny trick, then the misses took it out and the alternator siezed 50 odd miles away from home. So have a look at that. I was not popular that day....

Check the water pump and the alternator, not just the pulleys, idlers and tensioners ...
 
Changed front 2 ujs seemed to have play but in tacked so battled to fit them to find squeak still present and found few more probs to sort. Rear brake pads have no retainer on n/s so pads loose and scoring disk. Think this is sound! Also found exhaust carbon near turbo and manifold not sure where issue is fully
