Subsequent Work

Only for vehicles with petrol particle filter 

1. Carry out particle filter regeneration.
   • WM, 267429 - REGENERATING PARTICLE FILTER

   All vehicles  (except R4 engine)

2. Adapt sensor wheel.

   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. 
3. Only for V6T:
   1. 3.1  Select control unit for engine electronics (DME). 
   2. 3.2  Select Maintenance/repairs  tab
   3. 3.3  Perform sensor wheel adaptation reset. 
   4. 3.4  Perform sensor wheel adaptation with adaptation drive. 
      1. 3.4.1  Get a second person to check the PIWIS Tester  while you are driving.
      2. 3.4.2  Select control unit for engine electronics (DME). 
      3. 3.4.3  Select the "Actual values/input signals"  tab.
      4. 3.4.4  Select the "General"  group.
      5. 3.4.5  Select the actual value "Engine speed and engine torque". 
      6. 3.4.6  Select the "Misfiring"  group.
      7. 3.4.7  Note the actual value "Segment adaptation for rough running, status". 

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

      8. 3.4.8  Perform adaptation drive until actual value segment adaptation for rough running, status  displays "0"  → Adaptation is complete. 

         This procedure must be carried out at least 11 x. 

      9. 3.4.9  Bring combustion engine to operating temperature.
      10. 3.4.10  Set "Normal" drive mode with "Manual" transmission mode in 2nd gear.
      11. 3.4.11  Engine speed → 1600 and 2400 rpm.
      12. 3.4.12  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. 3.4.13  Overrun phase (accelerator pedal not pressed, no fuel injection) for at least two seconds each.
