MT 345e regen frequency

[Alan57]

My MT 345e, bought last summer, has had 4 regens in 48 hrs of use. We live in the city and only get to the farm on weekends where I use the tractor for grading driveway,occasional bush hogging and fel work.The first regen was at 14.6 hrs next 25hrs, 39.8 hrs and 48.2 hrs. Which seems pretty frequent. I run rpm’s at 22 for most work except when using the pto.
Each time it starts with the engine error light coming on and the regen light along with code FOO. After a minute or two the engine erro goes off and the regen heat light comes on. The tractor does it’s regen while I continue working the tractor. This takes about 20 minutes to complete and then it’s back to normal. Is this too frequent and if so what is causing this?

Your location would assist. Elevation and temperature may be contributing factors.

How many engine hours on the clock? Check the exhaust flow unions for tight connections to be sure there are no air leaks.

Stale or condensation contaminated fuel?

My eight year old, one-owner tractor, which only I operate, regenerates regularly every sixty engine hours.

Not sure what in the OP's post lead you to believe he bought this tractor used.

Alan, Maybe the load on the tractor has been light. That would cause more frequent regens. I suggest you ask your dealer about it and see what they recommend.

I must have processed information incorrectly. I will edit. Thanks.

I have regens nearly as often as you, 13-15hrs, dealer says it's normal. I have a MT240he

Should be closer to every 25+ hrs. I have gone about 30-35hrs between regens when running near constantly 1800RPM or more for FEL, tiller or brush hog work.

I appreciate the response and I will check the exhaust flow unions. Will also speak to the dealer next chance I get.
Thanks again and have a Happy 4th everyone!

F00 is only part of the dashboard code. There should be a code above or below that one.

Is the error light yellow or red?

You could have a bad DPF pressure sensor depending on the code telling the computer it's full.

Dealer would be your best bet because it should be under warranty.

"...is not THAT abnormal" funny how that is written, meaning it is abnormal, but not enough to look for a cause.

The error light was yellow. I’ve never noticed anything other than the F00 on the dash, I may have missed it if it did. Next time I will pay close attention to see if there is another code flashing. Thanks for the response.
