Kubota SVL95 2S E9510

[gwayJoe]

with the engine running, I filled diesel. While filling the diesel, e9510 - DEF injector. Is this coincidence? Appreciate any thoughts on the matter... Joe

Did you put diesel in the DEF tank?
Is there DEF in the tank?
If not then it failed for some other reason.

They've had TONS of issues with the DEF tank sensors. Make sure you have the latest one. Keep the tank topped off is the biggest help.

Thank you for your reply.. Please let me know how to be sure I have the latest tank sensor. I’m not the original owner. The blue light DEF display indicates a full DEF tank. Is it the DEF tank or Diesel tank that it’s important to keep topped off? To be sure, I do like to keep diesel topped off - and that was not the case when adding diesel to the diesel tank when the error code appeared. Thanks again and as above: how to know if the tank sensor is outdated or up to date.

Thank you for your help. It appears to have failed for some other reason as the console blue lights indicate a full DEF tank. The problem appeared while I was putting diesel in the diesel tank. Thanks Joe

It has nothing to do with any sensor or even the DEF tank or tank header. The E:9510 error is a UREA INJECTOR ERROR. There may be other DTC's (diagnostic trouble codes) stored on the ECU or the ACU.
It is a problem related to the DEF injector mounted into the mixing tube on the SCR muffler. There is a failure of the injector or damage to the wiring for the injector. To gain access to the injector, you must remove the intercooler/cover plate assembly. The injector is in the upper LH corner of the opening.

If the SVL is less than 5 years old, contact your dealer as it could very likely be repaired under the emissions warranty. They will connect Diagmaster as their first step and get the complete story.
Ask your dealer to check for any PSB's that might not have been completed including the fuel filter upgrade. All they will need is your machine's serial number to check.

Thank you for your assistance whitetiger; I very much appreciate it. Without a code reader device, is there any way to determine whether any other DTC's are stored on the ECU or ACU? My farm is a considerable distance from the nearest Kubota. (As of yesterday, the tech at that Kubota was locked out of the serial number section of their computer. I am to call back this pm 12/28.) In the interim, I will follow your lead and visually inspect wiring and what might be seen of the injector.
I've had any number of curious coincidences mislead me over the years - who hasn't? Nevertheless: my diesel fuel was at the edge of redline when, with machine running, I added red diesel and immediately upon seating myself saw and heard warning codes. I saw nothing unusual in the fuel. Still and all - do you think the fuel might be an issue even allowing for (as I understand the system) the urea injector is modifying exhaust? Thank you, Joe K

You can also disconnect the wiring harness connector from the injector to see if any DEF has leaked through the injector into the wiring harness itself.

The only possible way diesel fuel could affect the DEF injector is if the fuel was added to the DEF tank.

Thank you, Joe K

Whitetiger - I am happy to report your diagnosis correct. I changed the DEF injector maybe six hours ago and have happily seen no error codes. Much obliged for sure. For those interested: Whitetiger gave me the correct answer last week of December. I delayed in part because as my original message said, the DEF error showed up even as I was filling diesel into machine. How could that not be somehow related? Also: if I let the machine sit up unused for several days, the error code would not immediately appear. The machine would run for as much as twenty minutes without coding... More confusion.... In any event, the problem appears to have been solved and again my thanks to whitetiger and others who sought to help.
