Winter Fronts.....I found the perfect ones!
I have had diesel VW products for years, and now currently have an 02 Golf TDI on veggie, a 2013 Touareg 3.0 TDi and I also have a Bimmer that I have had cold weather issues with.
2 years ago my service garage, Frank Motors in Winnipeg, started making and selling winter fronts to fit most VW's to current as I understand. The are not vinyl which I tried and hated after 2 years. Rip stop nylon, good straps with an insulation pad. Oil temps on my Touareg up to 90 C in stop and go city at -30C within 35-40 minutes. On the Golf, can use veggie at the same temps within 45 minutes stop and go city. At -40 on the highway oil temps come even faster and the heat retention when parked is amazing. On the Bimmer, no more sludge in city driving. Best of all, less fuel consumption and way better heat.. For the 80 or 90 bucks I paid, would highly recommend you contact them to see if they can supply you one. OH, machine washable so they look great every year when I put them back on!
