Strange whisling noise in engine
Posted: Wed Jun 03, 2026 9:36 am
Hey there guys...
Steven here...VW Scirocco 2010 Mk3 dsg
So I have the strangest occurrence that can not be diagnosed by my local mechanic...
On start up a whistling sound can be heard...almost like a noisy fan belt, but not...
When revving it worsens...
If I switch off and restart a couple times the noise goes away and does not come back...
Initial thoughts were pcv unit which was replaced and not solved issue...
Any ideas from your side...
Thanks
