XR4155 F02 & F11

[JCarterLLC]

My LS XR4155 will run for 10-12 minutes and goes into "limp mode" while throwing the F02 and F11 codes. I had this issue two years back. I hauled it to the LS dealership for repairs. After 2 weeks, at pickup and $1,100 later, I was told they could not find an issue. The only thing they said they did was hook up to computer and clear faults. Periodically the past 2 years, if I did get the F11 code, I would "regen" the tractor and that took care of the problem. Well this morning, about 10 minutes into dragging the pasture, it faulted out and went into "limp mode". I have "regen" the tractor several times with no luck this time. Has anyone out there had this issue? I'm at a loss here and I really don't have much confidence at the local dealership. Any help would be greatly appreciated. I need to get up and running soon. Thank you in advance.

If it's throwing s636 and both yellow and red lights are on with those two F codes, it could be P0335 Crank over speed/gap lost fault #11 on list. If s27 & those codes with only a solid red light, it could be EGR related. Here's a list of fault code combinations from the service manual. maybe this helps you run it down

Thank you! I’m not sure of the number with scanning. The F02 & F11 flash up on my instrument panel. I’m going to pick up a scanner and hopefully get a starting point.
Thanks again for your time.

Drain your fuel filter. Over years had this problem many times throws weird codes. Also watch the EGR. If it falls apart it allows full flow of hot air into turbo and burns seals in turbo then dumps oils into dpf filter
And that baby is expensive .. I have been told that if filter is plugged with oil they can be cooked out. But also if your tractor is used on your property not commercial there is a loophole too allow bypass. We have 1500 hrs on our 4155. Smog stuff is the biggest issue.
