Just curious, did they quote you a shop rate? Wondering if they are at $200 per hour yet? How many hours on the tractor?
170 hours. That’s probably going to be my issue over time, I don’t use it a lot.
Ended up being a sensor wire came loose - the code hinted at this as well.
Luckily I think have have a decent dealer. $160 and done at my barn. Rerouted wires, checked filters,etc
Yeah, the DEF and more particularly the DPF system are problematic if you use them lightly, or in "on a few minutes, then shut off again" situations.
My 100hp tractor only has the DPF, but I use it at high rpm's, and usually all day when I run it. That way the DPF has the rpm's and time to clean the filter properly.
If I have a short, quick job like putting out a couple of round bales for the cattle, or anything else that's a short job, I use my 75hp, which has neither DEF or a DPF.
