    1. Set the vehicle into active grille wash mode sequence by starting the engine, set the vehicle into sand mode. After 20 seconds the active grille will open. Repeat this process to replicate the "rattle" noise and determine if the rattling is coming from the upper or lower active grille

      Does the rattling noise come from the upper active grille?

      Yes  : If the rattling noise is coming from the upper  active grille GO to G2.

      No  : If the rattling noise is coming from the lower  active grille GO to  G3.

  2. G2: RATTLE NOISE - REPAIR PROCESS FOR THE UPPER ACTIVE GRILLE

    3. Hold the upper active grille vane pack with two hands and gently shake it to allow identification of the rattle noise location. This could either be the frame of the grille rattling against the outer frame or the individual grille elements rubbing against each other when closing
