Evening all. I have a weird slow release of air sound after the throttle is released when just pottering about. I here he usual chatter sound from the air box then immediately after there's this weird air leak sound like a whistle noise. Is this normal or should I be investigating it.

Car Spec is standard apart from mountune intake, Miltek and stage 1 Colin's map..

Thanks all hope you no what it could be?

Had a similar noise in my mk5 golf, was the divetor valve had perished.

It's normal mate. It's from the recirc valve and is commonly known as the mouse. To eradicate it, most people fit an uprated one, such as Mountune or Forge.
