Task, convenience closing via air recirculation (except vehicles as of model year 09 /YoM 08 with code (494) USA version or code (460) Canada version)
By pressing the air recirculation switch (N22s2) (without code (581)

Comfort automatic air conditioning) or air recirculation switch (N22/7s2) (with code (581) Comfort automatic air conditioning) for longer than 1.5, the convenience closing function is activated. The left door control unit (N69/1) stores the momentary position of the left side window and closes it in the automatic mode if it is open.
When the convenience closing function is completed and the recirculation air switch (N22s2) (without code (581) comfort automatic air conditioning) or recirculation air switch (N22/7s2) (with code (581) comfort automatic air conditioning) is pressed for longer than 1.5, the left side window is moved back to the stored position.

The left door control unit (N69/1) is connected to the interior CAN (CAN B) for exchanging data.
