Freightliner M2 DPF Issues
Posted on 1/2/19 at 7:54 am

2012 Freightliner M2 with a Cummins
Threw a bunch of parts at it along with multiple forced regens from May to October. Had the SCR (Filter System) replaced in October. Threw a few more parts at it along with an ECM update last month.
Still getting Stop Engine light and throwing it into D Rate mode.
FL dealership says local shop might not have installed the correct "updated SCR"?
Any help is appreciated, this DPF is nothing but a time and money pit.

Isx cummins?
Without part numbers of what was done and a ESN I really cant help but you can help yourself a bit. Create an account on quickserve.cummins.com, you get like 3 serial numbers for free. Full access to service bulletins, service manuals, etc. You can do a lot of education for yourself that way with cummins documentation rather than what you hear on the internet.

I'm not a mechanic but I'm in trucking operations. but you are correct DPF is a money pit, especially those between 2008 and about 2014. I know it's easy for me to spend your money, but I'd cut my losses.

Yea it sucks but it is the only reason we still have diesels.

Thank you DS.
I am going to have a forced regen done on it in the morning and get it to the shop for a last ditch effort. In the meantime I will sign up on that site.
If I were to buy a new 2019 unit (not necessarily FL), can i get it without this DPF system?

No. All on-highway diesels currently have it and will have it into the foreseeable future. Theres some big medium speed engines out there doing it without any exhaust treatment technology but I dont think you'll ever see that make it to the highway market.
That said, the newest systems with urea injection are very good. They are much easier on the engine and all of the emission control equipment since the NOx is handled by the urea. If I was buying a diesel I would want the newest one they make. The tech is evolving yearly but we've hit a spot over the last 3 3ish years where we have a pretty good handle on how to make it reliable.
Plugging the dpf is usually an indicator of high idle times, frequent short trips, frequent interrupted regens, or fuel/oil issues. If it is actually plugging that much and not just having sensor problems than you might have a lemon case.
