2009 international prostar amber lights and warn engine

Just bought truck a month ago from freightliner and I have been in and out of the shop ever since I got the truck. Me and my farther in law are doing team and the whole owner operator idea is starting to bite me in the butt. I wish I could turn the truck back in and get my money back and just cut my losses. Unfortunately when you sign the dotted line your screwed. Anyways I've already payed to have fixed various problems that have popped up like were the clamp to the DPF filter was broke, Replaced batteries from a bad alternator that was replaced at the dealership, replaced a coolant reservoir that developed a leak, fixed various issues myself that I've found from where they had left the air intake hose lose, and had to get the turbo retiightened from were the turbo was making a bad whistling noise. My biggest problem right now that I've had that seems to never get fixed is a warn engine and a amber light. I keep getting active 4214 and 2637 codes saying the doc is plugged. Took to frieghtliner in Los Angeles and the said it was a sensor issue. So I had paid for that and it worked till I got back to the east coast. It came back on in PA and I took it to the frieghtliner in Hagerstown MD. They said the DOC was clean but they said the problem was a faulty aftermarket filter that the dealership put on there . They put a new cummins filter on there, replaced the catalyst converter, did a ECM update and sent me on my way. $5000 later stupid thing comes on again in Illinois. I decided to say the hell with it and run anyways because I'm having a ton of down time and it's making it impossible to make truck payment . Anyways I pull into Walcott Iowa, turn the truck off , fuel up and light goes off. This week Light came on again the other day going down a hill in Missouri for 5 seconds. Light goes off so I just wrote it off to a fluke. Yesterday me and my father law took a break in Elko NV because we were running low on hours and when we woke up this morning, about twenty miles down the road it comes on again.. Anyways we've took it the Reno NV freightliner because we hear that it can degenerate and shut the engine down and that I can't afford a tow bill right now we decided to take it in to get it looked at. It has a buyers assurance warranty for two
months and it goes out in a week. All of the stuff that wasn't covered like the petty stuff I listed above has cost me a fortune . Downtime is killing me also because in Hagerstown I was down for a week while they tried to look at it. Anyways if anybody know a or have ever heard of the issue before let me know. Any info would be greatly appreciated.

 

I bought it from thefreightliner dealership and it has a freightliner warranty. No doser on this truck because it's pre DEF

 

Also when light comes on its stays on. I don't normally idle the truck. If I do it's just for a few min. Mileage is 637,000. It flashed once in Missouri, the other time it's stayed on for two hours till we shut the truck off. The other times we've went 3 or 4 hours but we've went to the dealership to get it fixed from the threat of the truck degenerating

 

Thanks for the info

 

There saying a EGR valve needs to be replaced and the DOC catalyst needs to be replaced also. Is that the Dozer you was talking about? If not how much do one of those things cost.
