    NOTE:

    Always refill the VVAA module with lubricant oil after fitting it on the engine in order to pass the test from cold the first time. Failure to fill the VVAA module with oil could result in operating problems.

  11. Refill the VVAA module lubrication circuit with the prescribed oil through the first valve (1), with a maximum pressure of 4 bar, taking care to avoid contact with the valve.
  12. Use the prescribed type SAE 0W-30 ACEA C2 / API SN in the VVAA module using a graduated syringe.
    NOTE:

    The oil quantity for the first filling is 420 cm3 (40° C).

  13. Wait 60 minutes before starting the engine to ensure that the engine valves are closed.
  14. Install the cylinder head cover. Refer to COVER(S), CYLINDER HEAD, REMOVAL AND INSTALLATION  .
