    Note

    If the component was replaced because of a leak, perform the air dryer regeneration procedure to purge the accumulated moisture from the dryer. See Air Dryer - Tesla Air Suspension (Regenerate), and add correction code 31101008 as a separate activity to the Service Visit.

  7. Raise the vehicle on a 4-post lift and t Torque all suspension components while the vehicle is at ride height.
  8. Refer to the Alignment Requirement tables to determine whether an EPAS alignment check (EC) or four wheel alignment check (AC) is necessary. If performed, add the alignment check/adjust as a separate activity. See Alignment Requirement - Suspension.
