Correction code 18201702 0.42 NOTA: Salvo diversa ed esplicita indicazione nella procedura, il codice modifica e il relativo FRT associato, riflettono tutto il lavoro richiesto per l'esecuzione di questa procedura, incluse le procedure collegate. Non cumulare i codici modifica a meno che non venga detto esplicitamente di farlo. NOTA: Consultare la Tempistica tariffe fisse per saperne di più sui tempi forfettari e su come essi vengono creati. NOTA: Consultare Protezione personale per assicurarsi di indossare i DPI adatti quando si esegue la procedura descritta di seguito. NOTA: Vedere per le pratiche di lavoro in sicurezza.

  • 2024-09-12: Added note on adding correction code for refrigerant - recovery/recharge as a separate activity to the Service Visit.
  • 2024-02-28: Updated the routines.
Note
This procedure requires the A/C Refrigerant (Recovery and Recharge) procedure to be performed. If not already automatically added to the Service Visit, add correction code 18200102 as a separate correction within the same activity to the Service Visit.

Remove

  1. Remove the underhood storage unit. See Underhood Storage Unit (Remove and Replace).
  2. Remove the HEPA filter. See .
  3. Recover the A/C refrigerant. See .
  4. Remove the fresh intake duct. See Duct - Fresh Intake (Remove and Replace).
  5. Remove the 12V/LV auxiliary battery. See .
  6. Remove the bolts (x2) that attach the supermanifold to HVAC A/C line to the HVAC assembly.
    Tip
    Use of the following tool(s) is recommended:
    • 13 mm socket
  7. Remove the nut that attaches the supermanifold to HVAC A/C line to the supermanifold.
    Tip
    This nut is behind the supermanifold to compressor A/C line.
    Tip
    Use of the following tool(s) is recommended:
    • 13 mm socket
  8. Release the supermanifold to HVAC A/C line from the supermanifold, and then move the A/C line rearwards and up to remove it.

Install

  1. Position the supermanifold to HVAC A/C line on the supermanifold, inserting the A/C line stud into the stud hole on the supermanifold.
    Note
    Lubricate the new seal washers with the appropriate A/C oil. See for A/C oil specifications.
    Tip
    Reach under the supermanifold to position the A/C line.
    Tip
    Look through the supermanifold stud hole to help locate the A/C line stud.
  2. Install the nut that attaches the supermanifold to HVAC A/C line to the supermanifold.
    36 Nm (26.5 lbs-ft)
    Tip
    This nut is behind the supermanifold to compressor A/C line.
    Tip
    Use of the following tool(s) is recommended:
    • 13 mm socket
  3. Install the bolts (x2) that attach the supermanifold to HVAC A/C line to the HVAC assembly.
    28 Nm (20.6 lbs-ft)
    Tip
    Use of the following tool(s) is recommended:
    • 13 mm socket
  4. Begin the vacuum leak test and then return to this procedure. See #TASK_AWW_PQM_TLB.
  5. Install the 12V/LV auxiliary battery. See .
  6. Install the fresh intake duct. See Duct - Fresh Intake (Remove and Replace).
  7. When the vacuum leak test is complete, inject the appropriate amount of oil back into the A/C system. See #TASK_AWW_PQM_TLB.
  8. Recharge the A/C refrigerant. See #TASK_QGF_HNZ_QLB.
  9. Connect 12V/LV power. See 12V/LV Power (Disconnect and Connect).
  10. Unlock the vehicle gateway. See .
  11. On the touchscreen, touch Service Mode > Thermal > Sensors and Valves > Run Heat Pump Commissioning and select Run, and then allow the routine to complete.
  12. Tap Actions > Test Thermal Performance, select Run, and allow the routine to complete.
  13. Tap Actions > Test HVAC Performance, select Run, and allow the routine to complete.
  14. Exit Service Mode. See .
  15. Install the HEPA filter. See .
