That bloody cold - 54 F!!!

This morning was -23 C and after having the block heater on for 3hrs, the car started on normal glow plugs cycle and it was smooth. I know its a newer diesel but it still makes me happy that it can start no problemo.

Last time it was -23C I did not plug it in and it started good too, but I dont want to stress the engine/starter etc if I dont need to.
