Hi guys iv recently noticed a weird wurring sound. When i have my windows up music off i can hear a wurring kind of sound when im driving along which gets slightly louder when i put my foot down and also wurrs when i let of kind of like something is winding down it sounds like its coming from round by the turbo when im driving and power dosnt seem to bad did think the other day it felt slow but wasnt sure. Anyone know?

Does it sound related to the engine speed or actual speed?

Duno its hard to say just took my dad out snd it didnt do it.... seems to only do it after i been driving it for awhile i also get a wine after u put my foot down like its windin down and also when i rev the car and let off it makes a wining sound duno if im just being parnoid seein as iv never owned a tdi before
