Vacuum System

Function
On vehicles with automatic air conditioning all flaps (38, 39, 41, 44, 45 and 46) serving for the air distribution are actuated by the vacuum system.

The vacuum is connected to the switchover valve block (Y11/3) via the valve block (36) and the cockpit separation point (35). Depending on the settings on the pushbutton control module the individual flaps (38, 39, 41, 44, 45 and 46) are released for control by the switchover valve block (Y11/3).
