No power when accelerating

2014 Freightliner Sprinter 2400 with 4 cylinder 2.1, 168k miles.

So I bought a newer sprinter after having so many headaches with my t1n's, and now I'm facing issues in the first 2k miles. Starting to hate how finicky these things are. I noticed it bogging down on the interstate (dropped to 60 while going uphill), and the CEL came on. In town it's really slow to accelerate, though downhill I can still get it up to 75 and if I down shift it will go over 3k rpm. Hooked up my icarsoft mb II and found codes for EGR excessive and dpf soot levels. After reading a bunch of threads about dpf symptoms it seemed like a cleaning was worth a try, so I used liqui moly dpf cleaner and purge and ran it for 30 minutes at highway speed. According to my datastream it never got over 580 degrees in the catalyst so I don't think the regen was triggered. After resetting cel still no change. It just comes back on after a cycle (the egr code did not reappear but the dpf one did).

Anybody know if I can manually trigger regen using the icarsoft? What else can I try? I wrote down exact codes but can't find them at the moment.

Oh and two things I forgot to mention: when this first happened it was really low on diesel. Also, I had my first oil change done about a week ago (they used Northland 5w-40). Anybody know how I can check to see if it meets the low-ash specs?

Here are the codes I got, both current and stored:
P246364 Soot content of the dpf not ok. There is an implausible signal.
P246385 (or P246388, can't read my handwriting) soot content not ok, there is a signal above the permissible limit value

Also these:
P303231
9100 can bus-fault, stored

And I'm sure there was an egr one that I can't find currently.

You're going to need a scanner that reads live data. In your search did you come across the advice from Dennis to get temp and atmospheric pressure values from sensors, key on engine off?

I did not come across that thread, but I'll look it up. The icarsoft mb II does provide live data so I should have what I need.

Regen will not start when on reserve fuel.

So my atmo pressure is 29.1 inHG, and my ambient temp is 77. This is key on engine off. Weather site says current pressure is 29.8.

Your 2015 should still have some 100k emissions warranty left.
First take the Northland 5w-40 oil out and put in some oil that meets the correct specifications (it will be 0W-30 or 5W-30) MB-BEVO List 229.52
https://bevo.mercedes-benz.com/bevolisten/229.52_en.html
Who is "they" (they used Northland 5w-40)......I hope it wasn't a dealer as the wrong oil can very quickly cause excessive soot/ash in your DPF as
well as the higher sulfur can kill the catalysts in your convertors.
If the Northland 5W-40 is not a low SPAsh oil, yoiu might have a claim against "them" for destroying your emissions systems devices.
If you have < 100K miles, the smart move here would be to take it to an authorized Mercedes Benz Sprinter dealer and have them diagnose and
fix the issue (s) under warranty, but with the off brand oil, you may get a bit on an argument.
Why isn't your 7G-Tronic transmission downshifting when you start up a hill.
You can hardly feel it, but you will see it on the tachometer.
Perhaps due to the emissions faults you are in limp home mode pretty much all the time.
Definitely time for authorized MB Sprinter shop intervention.
They can force it to regen.....you probably cannot......just driving at highway speeds will not result in a
regen if the computer does not have one scheduled.....no matter what kind of "additive" you put in the fuel to
clean your DPF.

Thanks Roger. Unfortunately it has 168k miles. I'll talk to the lube shop that put this oil in there. To clean the DPF I sprayed Liqui Moly dpf cleaner directly into the dpf through the sensor port, followed by the purge.

The Sprinter mechanic that I use told me that using regular oil will ruin a DPF in about 700 miles.

I know you do not want to see a dealer , but there was an update to the CDI to fix this very issue with the DPF ash or soot content too high for regen. At 168 k miles I would be more worried about the right people touching your Sprinter and the 4cyl does not take 5w-40 but MB spec 229.52 5w-30 synthetic.
Next, at that milage you may be looking at anew DPF 168k miles is 68k miles more than the expected service life of 100k miles.

Good luck in your en devours

Northland oil? Oh My Word. Never heard of that brand....gotta Google it.

There have been a number of recent threads/posts by lindenengineering (currently on vacation) about the probable damage to your engine by running with a plugged DPF.

Is there any difference between Mobile 1 ESP 0w-30, and Mobil 1 ESP X1 0w30? Amazon's doesn't specify the x1

Oh man, sooo much reading. Update: I have been running this thing hoping for a regen, and I got one. Just as I hopped on the interstate temp went up to 900 so I got on it. Ran between 1100 and 1280 for about 25 minutes before it cooled down under 600. Got back in town and sure enough the van is running much better (not sure it feels 100% but way better). Problem is the cel didn't go out. Now the DEF light came on too. If it's not one thing it's another. Within 15 miles I put some DEF in there (only took about 2 gallons to reach the top of the filler neck...that's a bad sign). We drove back down to Ankeny for a job, still no change. Then on the way home yesterday I got the bloody countdown! Starts re10. I thought well maybe I didn't fill it enough so I got more DEF (DEfblue from Wally world), and it only accepted 1/4 gallon, so I'm sure I'm full. I'm down to 7 starts remaining so I haven't driven it again to test if it "just goes away", but I'm getting the following codes:
p204F (def fluid low according to another thread)
P204FFb
P13df00
P13e300 (engine starts limited according to another thread, wouldn't reset with a code erase as I had hoped)
555555

I'm trying to convince the Lube shop to change the oil on this thing as a first course of action, but in the meantime, have I "fixed" the DPF but ruined something in the DEF? Like sensors or heater, or pump?

FIRST!!!! Checking the BEVO list today, Northland's Eurosyn SAE 5W40 is approved by Mother. Sorry, I could not check this yesterday..... If they put this in, you are probably OK.

IRRC, "X1" is the latest in the endless name changing game of M1s low SAPs oil. Unless you are in the extreme cold climate, 5W30 would be the choice.

Well this is interesting....cascading failures.... Related? Unrelated? I'd take it to dealer.... or.... Dennis the mechanic.

Lots of discussion here about DEF. Two theories: top it up now and again and never let it trip the light /or count down; and, the drive'r till the dash light bitches then fill it up. A couple years ago, the latter seemed to be in favor. Today, it seems like folks are leaning toward the former. There's no hard data. It appears that the latter method leads to issues with the pumps, heaters, valves, etc., due to crystals forming in the system. Keeping it topped off may help prevent the formation of crystals (white creep) in the unwetted areas of the tank.

I believe even MB service advisors have shifted from 'drive it till the dash glows' to top off at will advice. Perhaps MB has more information and experience.

I top up believing that it helps keep the upper tank wetted and reducing the possibility of white creep. Also, the fill neck & cap are kept surgically clean. I use a designated funnel. Surgically clean and kept in a zip lock bag.

I'm almost certain they did not use Northland's Eurosyn version of the 5w40 since the manager readily admitted it does not meet the ash spec (229.51/229.52). He is claiming it was acceptable since it met 228.31. Is he in the wrong? Is the use of a 228.31 oil negligent in the 2.1L i4?

Wrong spec.....OM-651 uses MB 229.52!
Wrong weight.... OM-651 uses 0W-30 or 5W-30.
Suggest you ask the oil change shop manager to arrange to drain and refill your OM-651 engine with the correct specification/viscosity index oil, then underwrite a full diagnosis and repair at an authorized MB Sprinter dealer shop.
It will cost him (and his business insurance underwriter) a whole lot less than a lawsuit for his shoddy work and failure to use the specified lubricants!

Sorry they may have used the wrong oil........but.........that's the not cause of his DEF level sensor error or the DEF count down.

If this oil change to northland was it a one time recent event ?????.......it's also not he cause of the EGR or DPF codes. Low ash oil or lack of it is a long term issue over higher mileage.. which oil was used over the last 167000 miles is far more relevant. Using the right correct oil is important so they should change it to the right stuff. It's just not going to help cure your current engine emissions problems.
