    Hello:

    My 2012 VN Volvo Sleeper w/D13 and iShift releases air from somewhere when in gear and accelerating. The more I accelerate, the more air I hear, and I only notice it while driving, as reviving and idle doesn’t seem to produce the sound. There are no apparent performance issues resulting from this.

    Any ideas what may be causing this?

    Check the boots on the CAC system, my guess would be there is a tear in one and when your boost pressure goes up it's leaking out one of those boots.
