Check the oil level

WARNING: This page is about a different car, the 2013 BMW X5 M, 2012 BMW X5 M, 2011 BMW X5 M, and 2010 BMW X5 M. 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 oil level has dropped to the min. marking (2), you must inform the customer and 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.
