LS XG3032 Regen/dpf problems

[nickmags]

I have a 2016 xg3032. Dpf lite stays on all the time. Acts like it is going into regen, but never gets hot enough. Suspect burner/glow plug malf. Nearest dealer has changed hands and is now a joke. Can get parts, but have no way to know which part I need. Too expensive to guess and hope I get the right part. Please, constructive advice only. No "you should have bought such and such brand instead" or if you had such and such brand you wouldn't be having this issue. Money doesn't grow on trees, and time is something I try not to waste. I am 70+ and retired living on a very small military pension & social security. My question is, what happens if I just take out the particulate filter? Can I bypass/eliminate the whole regen/dpf mess.

I have read somewhere on here a hotter thermostat helped with a similar situation as yours, Letting the engine operate hotter.

There also was a post how taking the dpf apart and knocking holes threw it too alleviate any back pressure so there would be no more regen cycles. Drawback from that was there will be exhaust smoke instead of clean exhaust. I imagine eliminating the dpf would be the same.

With the XR3140h, the regen is every 50 hours like clockwork. No issues at almost 300 hours.

Hard to tell what it could be without a scan tool

It might be waiting for the coolant to reach a certain temp before starting the regen process. Being that its winter, probably not getting hot enough. Try working the tractor hard, high revs and working that engine.

How many hours on your tractor?

I'm not sure about bypassing the DPF, and I don't think thats the issue. If it were plugged up, you should be getting a dash error. Could be the injector is blocked, but again, throwing parts at it in hopes of fixing it, is not ideal. Without these stupid computers, the DPF system is actually pretty simple.

Thanks for the input. The regen temp lite does come on. Engine temp right about mid-gauge. Ran tractor for 1.5 hours at 2000+ RPM. Both lights stayed on. Near as I can tell engine temp is plenty hot enough. At least for past regen cycles. As for being winter, the outside temp was in the middle 50's. Should not be part of the problem.

Tractor has 1007.3 hrs.

Thanks for the reply. Must be nice, regen only every 50 hrs. Mine does it every 4 hours whether it needs it or not. What a total waste of fuel. EPA is throwin' out the baby with the bath water. Wondered about pokin' holes in the soot filter screen. Just don't want to end up in permanent limp mode.

I'm assuming there are no codes flashing on the dash. With that, a dealer could get the error codes of off it and diagnose the issue. Even crappy dealers can run a system diagnostics.

Unfortunately that is your only alternative. This would eliminate throwing parts at it.

Its not the epa’s fault that LS can’t figure out this pretty basic engineering challenge. Is your engine a shiabura? I believe that LS has used at least a few different engine suppliers over the years.

Kubota had problems with its B3350 (i think that was the model?) but quickly figured it out.
My kioti also regens every 40-50 hours. Like all these CUTs should.

Thanks for the response. No. No codes on the dash. I could probably narrow it down if I had a code or two.

Just couldn't resist that dig, could ya. Crap like that is what makes these sites so aggravating. But then, that's why you do isn't it. May your 'yoti run forever and you never need help.
