WARNING: This page is about a different car, the 2013 BMW M3, 2012 BMW M3, and 2011 BMW M3. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT: Adhere to the utmost cleanliness. Do not allow any dirt to enter the hydraulic system.
Using contaminated equipment to add fluid may introduce dirt particles into the fluid reservoir and significantly reduce the service life of the hydraulic steering system. Do not use any filler funnels or similar!

Visual inspection and leak test:Β 

Check connections, hoses and steering box for traces of fluid.

Check the oil level:Β 

Check fluid level with engine switched off at expansion tank of power steering/ride height control system. The fluid temperature should be approx. 20 Β° C here.

Ensure that the cap is fully screwed in prior to the fill level check.

If necessary, add hydraulic fluid (refer to STEERING -- OPERATING FLUIDS ) 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.Β
