BMW X5: Removing And Installing/Replacing DSC Yaw Sensor
IMPORTANT: Read and comply with notes on protection against
electrostatic damage (ESD
protection).
IMPORTANT: Do not kink floor panelling under any circumstances!
Necessary preliminary tasks:
- Remove right front seat.
- Lift floor panelling and fold back to one side
Remove floor inlay (2).
Unfasten screws.
Tightening torque, see 34 51 2AZ in 34 51 SLIP CONTROL SYSTEM (DSC)
Disconnect plug connection and remove yaw sensor (1).

Carry out calibration/adjustment of DSC sensor.
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
- Replacement lateral acceleration sensor
- Parameters and zero point of new sensors have been learn
Bleeding power steering:
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 Pentosin 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.
CHF Pentosin CHF11S
Fig. 59: Identifying CHF Pentosin CHF11S
- Thoroughly clean fluid reservoir and its immediate surroundings
- Check and correct fill level
NOTE: 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 in that the
marking on the dipstick is referred to a fluid temperature of 20ºC. With the
engine at normal operating temperature (approx. 50-60ºC 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.
- Start engine
- 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)
- Move steering wheel to straight-ahead position and turn off engine
- Check and correct fill level with engine stopped
- Check hydraulic system for leaks
Performing initial operation with test run:
WARNING: Danger 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 m 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.
- Check load; if necessary, remove load from the vehicle
- Bring engine up to operating temperature
NOTE: Hydraulic fluid temperature must be between 50ºC and 70ºC
(vehicle at normal operating temperature)
- Connect vehicle to BMW DIS or MoDiC diagnostic hardware.
- Start initial operation in SERVICE FUNCTIONS. Follow instructions
in DIS.
- Check and correct fill level with engine stopped
