Handling the EGR Cooler Exchange for Deutz BR 2.9 and 3.6 T4i DOConly Engines

When replacing the EGR cooler, it’s essential to store the exchange moment (operating hours) in the engine control unit. This step reinitializes the term-dependent aging function of the EGR cooler.

Steps to Perform the EGR Cooler Exchange

1. Press the “Set time cooler exchange” Button:
   • This action captures the current operating hours and records them as the date of the cooler exchange in the control unit.
     
2. Verify Operation Completion:
   • Ensure that the operation is completed successfully. The system should confirm that the cooler exchange time has been set.
     

Consequences of Incorrect Initialization

Failure to initialize or incorrect initialization of the term-dependent aging function of the EGR cooler can lead to the following issues:

• EGR Cooler Changed Without Runtime Adjustment in the Control Unit:
  • EGR correction is not active.
  • High smoke values.
  • Particulate emissions are exceeded.
  • Potential lack of power.
• EGR Cooler Not Changed and Term-Dependent Aging Function Still Activated:
  • EGR correction is active.
  • High NOx emissions (exceeding the limit).
