Subsequent Work

Only for vehicles with Otto particle filter (OPF) 

1. Carry out particle filter regeneration.

   > Refer to the appropriate Service Information for Regenerating particle filter

   All vehicles 

2. Adapt sensor wheel.
3. Only for R4:
   1. 3.1 Connect PIWIS Tester  to the vehicle.
   2. 3.2 Select engine electronics (DME)  control unit.
   3. 3.3 Select the Maintenance/repairs  tab.
   4. 3.4 Perform sensor wheel adaptation  .
   5. 3.5 Follow the instructions on the PIWIS Tester  .

   Information 

   • After removing, installing or replacing, perform the "Sensor wheel adaptation" function using the PIWIS Tester. 
   • To actively teach the adaptation, perform an adaptation drive together with another person. 
4. Only for V6T and V8T:
   1. 4.1 Select engine electronics (DME)  control unit.
   2. 4.2 Select the Maintenance/repairs  tab.
   3. 4.3 Perform sensor wheel adaptation reset  .
   4. 4.4 Perform sensor wheel adaptation with an adaptation drive  .
      1. 4.4.1 Get a second person to check the PIWIS Tester  while you are driving.
      2. 4.4.2 Select engine electronics (DME)  control unit.
      3. 4.4.3 Select the "Actual values/input signals"  tab.
      4. 4.4.4 Select the "General"  information.
      5. 4.4.5 Select the actual value "Engine speed and engine torque"  .
      6. 4.4.6 Select the "Misfiring"  information.
      7. 4.4.7 Note the actual value "Segment adaptation for rough running, status"  .

         Value "0" = adapted and (value "2" = not adapted)

         "Actual value segment adaptation for running smoothness" is not displayed on some vehicles and cannot be checked.

         "Sender wheel adaptation" must still be performed according to specifications.

      8. 4.4.8 Perform adaptation driving until Actual value segment adaptation for rough running, status  displays "0"  → Adaptation complete  .

         A journey must contain at least 11 cycles (acceleration => thrust) until the adaptation status changes. 

      9. 4.4.9 Set the operating temperature of the combustion engine.
      10. 4.4.10 Set driving mode "Normal" (for Hybird vehicles "Hybrid Auto") with "Manual" transmission mode in 2nd gear.
      11. 4.4.11 Engine speed → 1600 and 2400 rpm.
      12. 4.4.12 Generate a minimal load (50 to 150 Nm/37 to 111 ftlb.) → slight acceleration or slight uphill driving for at least three seconds each.
      13. 4.4.13 Overrun phase (accelerator pedal not pressed, no fuel injection) for at least two seconds.
