What's With The Air Distortion/vibration

[marklemac]

When I took the dealers demo car out for the day I noticed that when you are stationery and put a window down you get an awful air distortion effect going on, so much so that I couldn't tolerate it and put the window up.

But, if you put the other window down a bit the distortion/buffering is gone.

Took delivery of my 07 Black and it does the same thing.

Anyone else getting this ? Is there any cure.

It's almost like an air pressure thing going on.

When stationary?

Had an old Ford Capri and when the sunroof was open (when driving) it would cause a vacuum in the car to the extent your ears would pop! It did say in the manual that the ventilation controls should be open to let air back in

[marklemac]

yep when the car is stood still idling.

pop down a window and the air pressure/vacuum/whateveryouwant to call it is there. Put the window up and its gone. drop the other window and its gone.

And if you run down the OTHER window INSTEAD?

[marklemac]

Yep happens with the other window too.

It's almost like the engine is vibrating on idle and in turn is creating this air distortion effect.

[marklemac]

ok, this is definitely an idle based issue.

If I raise the revs when sat still the vibration/distortion goes, but I do need to take the revs up much higher.

As soon as the revs drop to idle the vibration is back.

Anyone else noticed this ? Like I said, not just my car, the 08 Platinum I took out did this also.
