I make sure :
windscreen wash is diluted to a higher washer fluid to water ratio - I also use the genuine VW stuff
Renew wiper blades if not done so in the last 12 months
Seal the windscreen with a dedicated sealant - eg Gtechniq G1 or Wolfs glass guard.
Treat door/boot seals with Aerospace 303 to stop them sticking / binding when the weather gets very cold

I'm happy enough I have all of this done last month now
3 coats jetseal and 2 coats autoglym super hd wax
3 coats G1 applied to all windows
New tyres to be delivered next week for winter
Wiper blades replaced
Gumfi Pledge added to all door seals
I like to add a nice warm steering wheel cover to keep my hands warm.....
As much as I don't want to admit it, my hands were freezing this morning so I tucked them into my jacket before grabbing the steering wheel. One of these would be great!
Several thin layers is always better than one thick layer. Some people underseal the undersides. As above, make sure the car is in good condition, check all tyre pressures incl spare. Think about a winter kit eg snow shovel, blanket, food etc. Breakdown cover.
Vw do rubber mats which are great for rain and snow.
I might try pick up those rubber mats from VW so. Have you gotten them before? Rough idea of price, going in next week for laser alignment and a few other bits so just want to budget.
