Your code speaks of a Cylinder #2 inbalance.?

Based on your statements, it sounds like you have a 6.0. As a result, my input is based on that assumption.
A contribution/balance fault is indicative of an injector going bad. In your case, sounds like you have a problem with the #2 injector. Have you noticed any more smoke than normal since the problem started or is it getting worse? If so, what color is the smoke?
Also, when was the last time you changed fuel filters? If it's been more than 15k miles I'd change them now. Also, check your oil to make sure it's not overfilled and check for presence of a diesel smell.
As far as the antifreeze, you indicated you're not losing "a lot." You shouldn't be losing any. There are several places that could be causing an antifreeze loss. These are a cracked EGR cooler, leaking EGR cooler hose, bad resevoir cap, leaking radiator hose, head gasket. I wouldn't automatically assume it's a head gasket issue.
