I own a 2012 vw golf wagon tdi and found it does not like northern ontario winters at all...first, the tires it comes with are terrible in snow and ice...sometimes slipping just getting out of the driveway...scary....I did not buy winter tires...never had a vehicle in my life where I bought winter tires so didn't think I needed them but with this vehicle, I don't feel safe with these original tires at all...
Also, hard to start in cold weather...if overnight temps drop to more than -14C or colder, needs to be plugged in or it won't start....or if you don't drive it everyday and there are cold temps at night, needs to be plugged in...
In addition, defroster completely ceased up during very cold weather and had to wait for hours until it finally decided to start working again once outside temps warmed up a little..
Needless to say , not impressed with cold weather performance....I understand that in 2014 a new golf wagon will be coming with possibly AWD and a more rugged exterior and interior to compete with Subaru Outback and the like.....definitely need AWD version of the tdi and if you don't have a garage to put one in the winter as it is now, and you live in a cold temp area, consider that this is a 3 season vehicle and may not be great for you...
