After just over 2 years and 21k miles (2009 2.0 TFSi Quattro S-Tronic, car now showing about 61k miles) of impeccable fault free service from my car, I'm leaving the fold..
Albeit the quattro is good, sadly never had chance to try it on snow with its winter tyres.
Moving over to a MK7 GTI...
One on my car makes similar noises depending on outside temp.
I simply sprayed the mechanism and seal areas with silicone oil. It helps but no 100%.
But do remember to open all doors or windows open for a while to ventilate the odour, and cover the interior with an old cloth to prevent over...
Label on the B pillar shows the 2.0TFSi Quattro S-Tronic is:
Normal tyres 225/40 18 XL 39 front, 35 rear.
Winter tyres 225/45 17 XL 42 front, 38 rear.
Funny that as I'd have thought both cars' weight and distribution would be almost exactly the same.
Perhaps it's down to suspension settings...

TIP..... If different makes of screen wash are used, this can lead to smearing...
