Structure and inner electrical connection

WARNING: This page does not describe the selected car, but rather 45 other vehicles, including the 2016 BMW M5, 2016 BMW 550i xDrive, 2016 BMW 550i, 2016 BMW 535i xDrive, and 2016 BMW 535i. However, it is still accessible from the selected car via links, so may be relevant.

Vacuum and ambient pressure are both present at the electro-pneumatic changeover valve. The engine control determines whether to relay system vacuum to the vacuum unit. There are only two working positions, on and off.
