High Pitched Whistling Noise from 2007 Volkswagen Passat 2.0T
Hello people!!! I have a 2007 Volkswagen Passat 2.0 T and couple of weeks now, I've been experiencing this very
loud high pitched whistling noise from the engine! Comes on in the morning after driving about 5/10mile. It stops
when I accelerate and starts when I take my foot off the accelerator pedal. I have been to a mechanic who says it's
the TURBO! However a friend of mine who has same car for over a year discussed with the mechanic who says it's
VACUUM. Now am really confused! Let have owned this car for barely three months and this is the first issue I'm
having with. Anybody!! Please assist
both answers could be right,odds on that it is the vacum as when the engine gets hot /up to temp it is sealing the hose so i would look at that first with the posibility of replacing the vacum hoses and posability of the egr valve as well if it is fitted to your model some did some didnt it depends on where in the world it was assembled
You can check the A/C and power steering belts. They nay be due for tensioning.
So I had the same issue. However, when I accelerated it did not make the sound but when I take my foot off of the gas it does. My sound it deafening though. The issue is the valve has broken. The valve also known as PCV, Crankcase, Oil seperator valve.
