Ah, the Internet age! OP posted one day prior to your comment. Sometimes a person gets caught up in other things. I wouldn't think it a fair assessment for only one or two days absence. But, I think no matter what someone's intent and or lack of follow up it's a good idea to lay out what folks believe with regards to trouble-shooting, as threads like these are of value to others: I suspect that many a myth can be nuked by folks following up with facts. All said, the fact that the OP gave no hour meter reading or age on the tractor makes me a bit suspicious: someone able to afford a tractor such as this, I'd hope, wouldn't be ignorant about these being pretty standard points to note.The OP joined, made the post and has not been back. Why start a conversation if you have no interest in the topic? They may not even have a tractor.
Regarding the basics of the claims about water in fuel, don't all tractors (newer ones, and especially bigger ones) have sensors for this? I know that my Kioti does: and I know that it works- I had issues with water from a stupid, cheap, locking fuel cap (came on the tractor; dealer kindly replaced with a revised/better one). HPFPs, as much as I understand/know, don't like water at all and that they'd tend to be the first thing to start balking: ones such as the Bosch CP4 like to outright explode. I suppose that a lot of water entering the combustion chamber is going to result in reduced combustion and higher particulate matter hitting the DPF. I would guess that water would, at the very least, cause increased wear to the HPFP, and that one would see reduced pressures as a result- lower fueling. Not familiar enough with common-rail; so, unsure how this would then affect the injectors. As RickB noted, and I seem to recall reading of such (though pertaining to diesel trucks), the Denso injectors are known to have issues. I think that being able to test the injectors would be the way to isolate this issue: not likely something regular dealers could do? CR fueling component parts swapping can be a pretty risky/costly approach; I can understand why dealers get nervous when facing such issues- I know that car/truck manufacturers have completely stonewalled dealers and customers: refer to VW, Ford, BMW (though BMW recently has started recalling for pump issues).
