lol

what he DID mention was that it may be a tiny leak somewhere and that its normal given the mileage hence nothing to worry about...

(what i will be doing when the car's off the road in the summer will be removing all the intercooler/turbo pipes, cleaning them all out and replacing the seals, see if that makes a difference)

I also have this noise on my tdi sport 105 mapped to around 145, doesn't happen all the time, but I'm 99% sure it should make the noise that it does as described by others... I've heared a few people say it might be one of the turbo/boost pipes that has a little split in it or a small hole?

Has anyone had this dealt with and actually rectified?

Could be a sign of worn turbo bearings, does it sometimes sound a bit like a police siren?

Luckily not, been told thats when there is a problem though as you said :)
