Re: How long to start 3.0 CRD
I have a 2008.5 CRD. And it gets pretty damn cold in Calgary. About the same temperature as you state. the manual says you should plug it in (block heater) whenever is gets below freezing... I do that and have had no issues like you are mentioning. I turn the key to on, watch the glow plug icon light and when it extiguishes, I start her up. The only times (x3) it has ever taken more than a few seconds to start, it threw a code... and the engine was hot.
