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 http://www.youtube.com/watch?v=8uAA3jLAY5o/ 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 have jacked up the car and tried to move the actuator by hand. It moves about 5mm. Should I be able to move it in situ? I have sprayed it with some WD40 just in case it is the arm that is stuck? I appreciate any advice you may have.
