I was curious how your A4 TDIs are starting in -30C like temps. I own an A3 and have a block heater to aid my car in commencing, but on A4 diesels there is no place to put a block heater. I know some of you guys have put supplementary coolant heaters on your cars, but my main focus is on the guys who don't have these heaters in your cars. How are you cars starting in these very cold temps. This morning it was -28C, my car was plugged in all night and still she didn't sound like she was happy to start. I though, had I not plugged her in it would have been 10 times worse. She may not have started at all. Any feedback would be appreciated.
