Having a look at the two vacuum valves on my 807. They hang under the engine bay upper valence to the left as look at the engine bay.
With the engine at idle the left one doesn't seem to be sucking or blowing but you can feel air around the filter trumpet. The right hand one sucks hard. If I disconnect the plug to the left hand one it sucks as hard as the right hand one.
My question is.... is this normal? Is the left hand one leaking a vacuum when at idle? Don't have access to Pp2K as yet. Just thought I would ask the question. Car seems fine but it does sound like the turbo/vacuum system whistles when the throttle is released or pushed hard.
