AdBlue removal process on John Deere

Reading and interpreting engine ECU faults. Once we’ve identified the various codes that are restricting the vehicle, we adjust the throttle aftertreatment program and set various variables to counteract the problem. We intervene at the heart of the engine management ECU, either Phoenix L14 L21 L33 or Bosch EDC17.

Which variables are emulated by program modification?

  • No need for AdBlue injection
  • AdBlue level correction and emulation
  • Defects permanently erased
  • AdBlue quality emulation
  • Nox sensor emulation
  • Removal of torque and power limits
  • Abolition of the maximum speed limit
  • Complete solution for AdBlue system virtualization on John Deere machines

The Bosch EDC17CV41 ECU: Eliminating faults and increasing engine power

Engine Control Unit, AdBlue, and Power Increase:

By reading and writing data, we gain access to the core of the engine ECU, specifically the Flash memory. Within this memory lie a multitude of engine operating and throttle parameters. Our skilled team of engineers can leverage this access to program engine data, thereby enhancing torque and power across all John Deere vehicles produced from 2000 to the present day.

Most of the faults encountered concern the Adblue system

The majority of encountered faults revolve around the Adblue system. By directly intervening in the engine ECU, we can eliminate all engine faults that impede the normal operation of your John Deere vehicle.
