(Start-up with test run of Dynamic Drive)
IMPORTANT:
After replacing the valve block, Dynamic Drive expandable hose or hydraulic pump, it is essential to perform the following operations to avoid fouling/contamination in the hydraulic system:
- Disconnect wiring harness from valve block (valves must be inactive)
- Fill hydraulic system (if necessary)
- Start the engine and run it for five minutes.
- Engine off
- Ignition ON
- Reconnect valve block wiring harness
- Perform start-up
NOTE:
The Service function start-up of Dynamic Drive must be carried out after:
- Work on the Dynamic Drive system which involved opening hydraulic lines
- Replacement/programming/encoding of Dynamic Drive control unit
- Replacement of lateral acceleration sensor
- Learning parameters and zero point of new sensors
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 oil reservoir and significantly reduce the service life of the hydraulic pump. 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! The oil temperature should be approx. 20°C 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 oil reservoirs or their caps with identification marks.
CHF Pentosin CHF11S
- Thoroughly clean fluid reservoir and its immediate surroundings
- Check and correct fill levelNOTE: The fill level can come to rest above the "MAX" mark when the engine is at normal operating temperature. This is dictated by the design as the marking on the oil dipstick is related to an oil temperature of 20°C. With the engine at normal operating temperature (approx. 50-60°C fluid temperature) adjust a fill height 15 mm above the "MAX" mark. Do not under any circumstances draw off the fluid to the "MAX" mark when the engine is at normal operating temperature.
Hydraulic fluid: BMW Service Operating Fluids - Start the engine and run it for five minutes.
- Check and correct fluid level with engine stopped
- Check hydraulic system for leak tightness
Performing start-up with test run:
WARNING:
Danger of injury!
Vehicle executes heavy rolling motions during start-up! Therefore observe the following specifications without fail:
Vehicle executes heavy rolling motions during start-up! Therefore observe the following specifications 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 perform start-up on vehicle hoist, wheel alignment analyser or similar!
- Avoid heavy loading!
- Check load status; if necessary, remove load from the vehicle
- Bring engine up to operating temperatureNOTE: Hydraulic fluid temperature must be between 50°C and 70°C (vehicle at normal operating temperature).
- Connect vehicle to BMW diagnosis system.
- Initiate start-up in the service function. Follow instructions in the diagnosis system.
- Check and correct fluid level with engine stopped
