Hi there

Don't know if this is the right place to post tis.
My customer has a funny vacuum sound in his airfilter housing after releasing the throttle.
It could be this startet after a tuning at another company.
I loaded an ori file, but sound is still there.
The car: Volvo xc90 2.4D from 2004

sounds like this one :
