Hi guys,
I have a question about this error, "Engine-ERROR P0093." Sorry for the long story below but I have doubts about what the dealer told me and then I had another failure right afterwards that I think is unrelated but I want to be sure.
I have a 2016 L47 and I was using it with a tree puller to pluck small trees (<1.5") at low speeds in M-L on a variable steepish grade (5-15º) and noticed that it seemed to be losing power but I didn't think too much about it because the slope I was working on was varying grade and I figured I was just on steeper part than I realized. A few minutes later it beeped and the display panel showed "Engine-ERROR P0093." I immediately moved to level terrain (50' away) and shut it down.
Neither my owner's manual or WSM shows this error anywhere and searching here, TBN, and Google generally revealed nothing. I called my dealer the next morning and he looked it up and told me it was a starter relay failure and that it likely wouldn't start.
Since I was grubbing out saplings from a new clearing and it was plausible that something had poked up inside and ripped some wires (it's happened before). I checked it out the next day and couldn't find any damaged wires anywhere, especially around the starter area. I tried the key and it fired right up. So I began gently using it again. After a little bit it seemed to start losing power again so I shut down again and remembered that I hadn't checked the air filter in a while. While checking it (it was dusty but not plugged) I noticed that the oil cooler radiator was completely plugged up with dust (engine temp was normal). So I let everything cool down and then mozied it back to the shop and used the air hose to give everything a good cleaning out.
I was able to use it for several hours the rest of the day with no more issues until the last hour of the day when hose from the loader valve's power beyond to the 3rd function valve blew in a spectacular geyser of $30/gal SUDT2! Now, my first thought was that I'd caught the hose on an unseen sapling-turned-spear but the area was completely clear and those was blown on the top side right at the crimp and following the seam. BTW-This is the FOURTH hose that's blown on me in only 220 hours and none of them have been due to external damage --but I think this is another story...
So here's my questions:
1) Can anybody confirm that P0093 is indeed a starter relay? I suspect it's actually HST oil temperature based on the reduced power coupled with plugged oil cooler and it went away when I cleaned the radiator
2) Does anybody think the latest hose to blow could be related to the P0093 above? I think they're either just coincidences or I really did hit something that snagged it and I just didn't notice it.
3) Has anybody else had problems with recent vintage Kubotas blowing hoses? I feel like the quality of factory hose is substandard. I had 1 FEL hose blow entirely around 20hrs and the other side was about to go when I had them fix the first one and at 100hrs two BH hoses blew.
Or maybe I have other pressures issues because I've also had both FEL cylinders that were leaking at the internal seals almost from the start, one grapple jaw cylinder seal shortly after than (3rd party grapple, no warranty on that one), and then not much later the BH thumb cylinder too. The dealer has done a pressure test twice because when I first got it was really weak and they said the pressures were fine, maybe on the high side of spec, but still in spec. I finally cured the weakness myself when I found several fittings were not tight from the factory and it was leaking and also admitting air.
I guess this part has turned into a bit of a rant. I've been very honest with how I'm using the tractor and what I'm doing with it and asked if I was abusing it or my expectations were off and every time he's assured me I wasn't doing anything wrong and it was just bad luck and they'd fix it. However, stuff keeps happening and my frustration is boiling over. I bought new so I could just make payments instead of repairs but instead I'm doing both. (I'm excluding the things I've broken myself due to bad operation because that's not their fault like the time I did snag a stick and it ripped out the 3rd function wires).
Anyway, thanks for listening and please let me know if have any answers to any of the above.
