Vacuum hoses
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.
The vacuum hoses transport the partial vacuum to the pressure converters/changeover valves and to the actuators. Leak-tightness and no blockage of the vacuum hoses are decisive for the function of the system.
The vacuum hoses must be checked for the following faults:
- Kinks
If the vacuum hoses are routed in radii that are too tight or over edges, kinks can occur.
- Squashed vacuum hoses
The vacuum hoses can be squashed by contacting components (for example acoustic cover).
- Cracks
Especially at the ends of the vacuum hoses, cracks can arise that lead to leaks.
NOTE: Cracks can be covered by the hose fabric!
