Default Hard start / no start just around freezing

This morning I had my 2nd time having issues with a hard start just around freezing, with having no issues when it's cold. It almost seems like it could be not calling for glow plugs, and I'm not sure if that's adjustable like it is on the ALH.

The car already has the "cold weather" kit for the intercooler, and I've not had any problems when it's much colder, it only happens at just around freezing (today it was 31F).

2011 Jetta TDI 6spd. ~101k

Previous: '02 Jetta TDI 5spd, ALH. Sold at 379k.

Have you tried removing the passenger side intercooler hose? One end has a normal hose clamp. I have the cold weather kit on my bug too, but still drained 2.5 cups of water out of the hose 2 months ago.
