Checking fluid level
WARNING: This page does not describe the selected car, but rather 21 other vehicles, including the 2015 BMW Alpina B7L, 2015 BMW Alpina B7, 2015 BMW 750i, 2015 BMW 750Li, and 2014 BMW Alpina B7L. However, it is still accessible from the selected car via links, so may be relevant.
Check fluid level with engine switched off at expansion tank of power steering/ride-height control system. The fluid temperature should be approx. 20°C here.
Ensure that the cap is fully screwed in prior to the fill level check.
If necessary, add HYDRAULIC FLUID up to Max. marking (1).
IMPORTANT:
If the fluid level has dropped to the Min. marking (2), you must check the power steering and ride-height control for leaks and issue a separate invoice for this work.
It is not enough merely to top up the fluid.
NOTE:
To avoid mix-ups when filling with hydraulic fluid, mark the fluid reservoirs or their caps with identification marks.
