As far as loosing coolant, pressurize the coolant system to a full 20 PSI and find where all the leaks are. You need to find out where that coolant is going. Check the back of the egr cooler to see if it is seeping as well.

As far as the regen lights.. when is the last time a thorough EGR tune-up was done to it?. Start with that...
