AAV = Valve. Electrically switched valve, on or off only.
AAR = Regulator. The AAR is both electrically controlled and engine heat controlled, slowly closes as the engine warms. Attached to the intercooler and the intake manifold (bipassing the throttle).

Sounds like you are describing the AAV. Is this from a 930 or SC?
