BMW 7 Series: Initial Operation With Test Run Of Dynamic Drive
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 equipment to add fluid may introduce dirt particles into the fluid reservoir and significantly reduce the service life of the ARS and power steering system. 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.

Bleeding hydraulic circuit
1. Thoroughly clean fluid reservoir and its immediate surroundings with cap closed
2. Check and correct fill level
NOTE: The fill level must not be above the "MAX" mark (80ºC) with the engine at normal operating temperature.
When filling observe temperature indication of dipstick.
Hydraulic fluid: see OPERATING FLUIDS.
3. Start engine.
4. Turn steering wheel left and right twice in each case up to full lock; if necessary, top up hydraulic fluid (e.g. if hydraulic system is completely drained).
5. Move steering wheel to straight-ahead position and turn off engine.
6. Check and correct fill level with engine stopped.
7. Check reworked components on hydraulic system for leaks.
Performing initial operation with test run
WARNING: Risk of injury! Vehicle executes heavy rolling motions during initial operation! Therefore observe the following instructions without fail:
- Do not allow any persons to remain in the vehicle or directly on the vehicle
- Keep the vehicle doors closed.
- Maintain a safety distance around the vehicle of 1 meter to persons, objects, walls etc.
- Vehicle must be standing horizontally with all wheels on a firm surface
- Do not under any circumstances carry out initial operation on a lifting platform, wheel alignment analyzer or similar!
- Avoid heavy loads
1. Check load; if necessary, remove load from the vehicle.
2. Bring engine up to operating temperature.
3. Connect vehicle to DIS or MoDiC.
4. Start initial operation in SERVICE FUNCTIONS. Follow instructions in Diagnosis and Information System.
5. Check fill level again with engine stationary and if necessary top up oil to 80º mark.
