Lightweight weedly little cars with thin tyres are best on snow. Like Ford Ka's.
The worst are 4WDs. You are tempted to venture down snowy lanes only to find the road blocked by a milk wagon. Then the van following you gets stuck. And so are you.
Thats why i have a mini for the winter. (i live at one of the highest points in the north of england so it snows alittle here

) I have used it since 1989 in the winter and never got stuck. The joy of 145 tyres.
The smug feeling passing 4x4s who have got stuck is so much fun.
The other advanges of having two cars and one that has little power is you learn to drive properly again. The other is when you start craving more power with the GTI as you got use to it, you swop back to the low powered car again for upto a week and you start to learn to drive properly again, then when you go back to the GTIs they feel quick, saved me a fortune in upgrades over the years!
Winter with DSG is one of the first things i looked into back in 2005 on the mk5. I found it odd that when other autos had a winter setting the DSG did not. They then introduced a type of winter setting on the TDI GT DSG (theres a button to reduce torque in front of the gear lever) but they never for some odd reason put it on other models.
