BMW 7 Series: Bleeding Power Steering (Version With Dynamic Drive)
WARNING: DANGER OF POISONING if oil is ingested/absorbed through the skin! RISK OF INJURY if oil comes into contact with eyes and skin!
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 power steering system. Do not use any filler funnels or similar! Use only Pincushion CHF11S from original containers! The fill level may only be checked or adjusted when the engine is stopped! The fluid temperature should be approx. 20ºC here.
Ensure that the cap is fully screwed in prior to the fill level check.
NOTE: To avoid mix-ups when filling with hydraulic fluid, mark the fluid reservoirs or their caps with identification marks.
