whistling noise going pass 40mph
Discussion
hi guys i got myself an astra h 2009 1.7cdti i realised when i go pass 40mph theirs a whistling noise coming from somewhere i have no idea where but its not loud but i could still hear it i wonder where its coming from when i drive below 40 its fine well sometimes it does it around 30-35 mph aswell could it be the turbo?
Turbo whistle will be easy to recognise, as it spins up whistle will rise/get louder, then die down as your foot comes off the throttle. Windscreen, door seal whistles will me more like when you watch an old black and white film and you hear the wind sound effect in the background, it will whistle up and down and vary a lot. I 'think' that made sense? :-)
