Air vent in door pillar is driving me nuts.

[Hedgecutter]

The air vent situated in the pillar just behind the driver`s ear whistles, unless I turn the ventilation fan off; then it will stop. Has anyone else noticed this, or got a quick cure? I noticed it last year, but have not been aware of it again until today, when it was very windy. It sounds just like wind whistling when one is indoors on a really windy day. Could there be a bit of transit trim protector film stuck in there, perhaps ? Thanks.

Not something I've ever noticed. GL with the diagnosis.

Make sure it's open

You could try dismantling it, or if you have access to Vagcom you can try the "reset and relearn all motor flaps" thing, it moves all AC flaps from 0% to 100% and relearns the positions, maybe that would help (although I doubt it)

Interesting... there is a fault in the ac on the "left hand temperature flap position motor". I`m just waiting for the part. I have

tried shutting and opening the vent. The noise has a variable pitch, just like the wind blowing through a gap. I wondered if the ducting behind the trim was loose.
