ADBLUE OFF VALTRA N N113 4.4L

VALTRA N N113 4.4L - AdBlue SCR Deactivation

We visited a customer in Łowicz County in the Łódź Voivodeship. The tractor experienced an issue with the AdBlue system, which triggered emission faults in the engine control unit and sudden entry into limp mode with a significant power limitation. On-site, we performed efficient diagnostics and successfully deactivated the problematic system in the BOSCH EDC17CV54 ECU. The performance drop issue was permanently resolved, and the machine regained its full dynamics and returned to efficient work without the risk of further downtime.

Why does the AdBlue system in VALTRA N N113 4.4L cause problems?

The SCR system in agricultural machinery often generates faults that prevent normal field work. The most common causes of failure include fluid dosing problems, which interrupt the exhaust purification cycle and activate the controller protection mode.

• Fluid crystallization: The SCR injector gets clogged with salt deposits, causing urea to leak and block the catalyst.

• NOx sensor failure: These components suffer damage from moisture and vibrations, sending false readings to the ECU.

• Catalyst wear: The catalytic coating loses its effectiveness, which directly triggers error codes.

• Electronic blocks: The engine control unit responds to any emission reduction malfunction by lowering machine performance.

How is AdBlue deactivation performed in VALTRA N N113 4.4L?

The modification involves a comprehensive change of the control software and disconnecting the actuators of the exhaust aftertreatment system. First, we connect diagnostic equipment to read error codes stored in the BOSCH EDC17CV54. Then, we upload a modified software file that permanently disables AdBlue support in the ECU memory. The final step is to confirm correct engine operation and the absence of errors.

How much does it cost to disable AdBlue in VALTRA N N113 4.4L?

The cost of this service for this model starts from 2500 PLN net. The final price depends on the scope of necessary electronic work.
