2012 kubota m135x engine problems?egr??

[Cmo18]

Hi guys,
I have a 2012 m135x with 850 hrs on it and up until now has been flawless. We uses it 90% for snow removal.

2 weeks ago problems started with a plugged air filter, tractor was blowing lots of black smoke, cleaned filter all was good. Then we had electrical issues with transmission and after a big bill from the dealer the tractor was back up and running. The dealer also noted the transmission was 15l low on fluid, which is strange because it was good before it went to the dealer. Once we got it back from the dealer we used it for 5 hrs and now the low oil pressure light is coming on, lots of blow by coming from vent tube, and it's shutting down when its warmed up. Engine oil is good, it does make loud noises when running and doesn't sound healthy.

Could the exhaust be plugged up from all the soot?? Egr problems? It doesn't have a dpf but feels like the engine is restricted bad causing blow by etc...anyone have any help or ideas?? I also may add when tractor is warmed up the transmission is way overfilled from dealer

Welcome to OTT from Alabama. What work did the dealer do?

The dealer found some corroded wires on top of the tranny that kept it from going into forward, and added 15l of tranny fluid...were still not sure how it lost all that fluid

When it is cold, what does the fluid level look like? 15L is an awful lot to be missing. Does sound like there is a big problem somewhere.

Yes 15l is a lot of fluid, when cold it's overfilled by 1/2" on the dipstick...

But it's now the engine that is scaring me, the service has been awful

Sounds like they overfilled it. I would drain enough fluid until it got back to where it is supposed to be. drain it into something clean so that you can use it later.

I'm not to worried about the tranny right now more worried about the engine problems. Is there any way to read the engine computer without the dealer?

Where would you guys start looking?

Compression gasses are building in the engine and it smells like something is burning up after a few minutes of running?

Sounds like you have a turbo problem, But that's a wild guess without more facts.

First you need to get the WSM for the tractor that will help diagnose the problems it's having.
