If you bypassed the PDF (sic) the chances dealer will work on it is pretty much zero.

Yes, proprietary dealer software is required to clear such codes.

You have backed yourself into a corner. :unsure:
A dealer will not (legally can not) work on your tractor since you've defeated / deleted the emissions system.
Most independents do not have the computer and software to work on a kubota.
And even if they did it would just fail it as the software will not just let them bypass the emissions requirement.

So I take it you've done all this work to delete / defeat / remove the emissions equipment and never looked at resetting or reprogramming the system that runs the emissions equipment.
I'm also betting that it either still does not run or it does not run properly.

Was the light on and the buzzer constant?

If not then it's a different issue than the DPF.

Hey why don't you call up who you bought the emulator from and ask them how to fix it! ;)
And yes the last statement is a joke! :p

I'm not understanding your issue.

The engine check light is not set because of it being a little over full on oil.
It on because there is an issue with the either the emissions system or it's sensors (very likely) or it has been overheated, and that will set the code, or it's not reading aa temp sensor.

Did you remove the DPF filter and all of the sensors?
Did your emulattor have connections for all the sensors?
Do you have the WSM (aka service manual)?

Aren't emissions systems warranted for longer than the tractor by quite a good amount? The M9960 is what, 2000-2004, so emissions systems should be under warranty? Maybe?

I believe most (all??) emissions warranties are 10 years.

Edit - looks like its a minimum of 8 years by federal law.

1/ the check engine light on b4 i installed DPF by pass kit.The DPF filter is still on the tractor i only replace the middle one with the pipe come with the PDF Kits.
2/ Yes the Emulattor come with all the connector..temperature sensor,differential presure sensor and rail fuel pressure sensor
3/The tractor never got over heat befor..

i saw when put the key to ignition both oil presure light and check engine light stay on..But when i start the key the oil presure light come off..Dont know if the problem is oil pressure..

Contact Reimer Tuning in Canada. They can send you a programmer along with the ability to clear codes related to emissions. You'll be looking at $2.5k to $3k but their stuff works, and works well. Tell them what you've done, the problems you're experiencing and see if they have any recommendations.

I've found Reimer Tuning and TM AG Tuning to offer solutions that work without any drama. Not cheap, but way cheaper than paying for a new DPF, and the other benefits are well worth the price of admission.

DPF ... not PDF ... and "filter" is redundant since that's what the F stands for. 😂

It's akin to saying DEF fluid or ATM machine ..... the F and M are enough.
