I would check operation of the glow plug circuit and then each glow plug. Hows you coolant level? is it dropping?

I have heard of a couple of case of 2007 CRDs where the bolts on the oil pump have come lose and caused major engine damage. I would get this inspected asap, maybe put an oil pressure gauge on it just to make sure oil pressure is ok.

It's common for the IC to leak, there are a few mobs around that do replacement units.

Hope this helps.
