Isx 15 cm2250 regen advice needed

[Tonka]

Hello, first off I'd just like to go on record and say this forum is legitimately awesome.

My question?

I have a 12 pete with a isx15 cm2250. Ive been having dpf problems. Regen light every 60- 90 miles. Turbo actuator
Fault codes, particulate filter outlet temp fault code and I can smell exhaust, sometimes it seems like I smell it through the vents in the truck. Ive recently had the dpf filter cleaned and baked. Although I havent gone through all the cleans that rawze Shows and suggests. Ive also noticed that I'm leaking coolant on the side of the turbo. Could this be the cause of dpf problems? Im not sure where but ive taken pics
            

Lastly, is this something I can fix with minimal experience or do I need a shop. I'm based near ATL

Thanks
