What is wrong, if anything?

Hi all,
I Have a VW Passat B6 2.0 TDI 140, which makes a whining noise a similar to a milk float but more mechanical and higher pitched but not overly loud or remotely police siren like. The car has done 56,000 miles, have a full service history and runs fine. I have no excess smoking or loss of power. On idle, the car makes the usual bulgarian tractor diesel noise, but when accelerating I can hear the low growl of the engine superimposed on top of the higher pitched noise.
This is exactly the noise my car is making

You hear the milk float type noise.
I have had the car serviced last week at a VW specialist garage (not main dealer but ex main dealer staffed place).
They have suggested that the turbo is on its way out and that the vanes are most likely stuck.
I am a little dubious about this and I get the feeling they just want me to pay for a turbo in the next 20,000 miles or so.
To me it sounds like there is air getting in somewhere it shouldn't such as in a leaky hose/ gasket? When reved at a stand still with bonnet open and listening I can hear a lot of air sucking in when putting foot on accelerator/ hiss release when taking foot off of accelerator.
It seems awfully low milage for a turbo to start to fail. The car is mainly thrashed along country lanes so I can't imagine I am not clearing deposits from the turbo which are likely to make it stick.
Basically I don't want to fork out for a new turbo if its not faulty and wish to know if the advise I am getting is likely to be correct and my suspicions unfounded.
Do sticky vanes create a noise or could it be something completely un turbo related?
I live in the Portsmouth area if anyone can suggest a good Diesel turbo specialist who can tell me what it is likely to be.
I appreciate any advice you may have.
