    As usual upon startup I can hear the secondary air pump engage. After warm up and just starting out in Drive I hear what seems to be the pump running again but not as loud. Anyone else have this happening?

    Are you referring to the vzzzttt sound when you get up to 5 MPH in forward or reverse? That’s the ABS test.

    Yep, that must be it. It does come from the same area as the air pump.
    Thank you
