Good morning,
Today I was driving to work with the window open and noticed a strange noise when coming off boost
Basically when backing off the acclerator I hear a high pitched squeeling noise that sounds like a dry bearing - however the noise only happens when I back off pretty suddenly. Only lasts a second or so like pressure is being released.
Am I correct to assume it is a blocked or semi blocked PCV - car is an 08 GTI, unmapped and isnt loosing any boost when under load.
For interest sakes how much is a replacement PCV?
Many thanks for your help in advance
