BMW 7 Series: Start-Up With Test Run Of Dynamic Drive (EPS Steering Gear)
NOTE: The Service function Initial operation of Dynamic Drive must be carried out after:
- Work on the Dynamic Drive system which involved opening hydraulic lines
- Replacement/Programming/Coding Dynamic Drive control unit (ICM - V - High)
IMPORTANT: Adhere to the utmost cleanliness. Do not allow any dirt to enter the hydraulic system.
Using contaminated auxiliary materials to add fluid may introduce dirt particles into the oil reservoir and significantly reduce the service life of ARS. Do not use any filler funnels or similar! Use only Pentosin CHF11S from original containers! The fill level may only be checked or adjusted when the engine is stopped! Adjust fill level if possible in middle between 20º and 80ºC.
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.
