New Passat (2 days old) - wind noise issues. Not happy!

[OilBurna]

My 7 year old b6 wagon id a quiet as a mouse could the have done something to the window frames when they did the tinting? Perhaps take back to dealer and compare to another wagon

Interestingly today I was out in the car and after having it parked in the sun for about 15 mins I got back in and when it started up there was a rather piercing whistle.

I tracked it to an air vent as I had air on full cold and the l/hand centre dash vent was almost closed and I think that caused it . When I backed the fan off and opened the vent it no longer did it.

Yeah, I'll concur with OilBurna. My 4 year old B7 Wagon has never made a sound apart from when I have the racks on.

The second issue - that loud hum at 122 is like a vibration that runs through the whole chassis, but has a "pitch" - like I could hum it. It is only at an exact speed, ease off or speed up by 2km/hr and it goes away. That one isn't such an issue because I don't drive at 120km/hr (much ...) but it says to me there is something not quite right. I will have the tyres checked at the 1000km checkup.

Thanks for the quick response

If you can duplicate problem at a lower road speed, could indicate problem not due air pressure on panels.
First, monitor oil temperature to ensure engine fully warmed up
Take note of tachometer reading at "122"
Manually select second gear from top ( Position 6 instead of 7)
Try driving about 10% below and above tacho reading.
Also try reasonably firm acceleration through this test area.

Try same revs in different gears Should tell if its a harmonic issue related to driveline or as said above different revs at the same speed

Speak to your dealers service department. There is a TPI on wind noises in the Passat which require a seal adjustment to fix it.
