Seal off hydraulic lines with plugs.
Necessary preliminary tasks:
- Disconnect BATTERY NEGATIVE LEAD
- Draw off and dispose off hydraulic fluid from fluid reservoir
- Secure ENGINE IN INSTALLATION POSITION
- Remove FRONT WHEELS
- Disconnect PLUG CONNECTION OF BOTH PULSE GENERATORS
- Remove both BRAKE CALIPERS FROM SWIVEL BEARING and tie up
- Remove REINFORCEMENT PLATE
- If necessary, remove steering gear cover on both sides
- Remove wheel suspension cover on both sides
- Remove LOWER STEERING SPINDLE FROM POWER STEERING GEAR
- If necessary, disconnect plug connection on EH converter and expose line up to engine carrier
- If necessary, disconnect plug connection on ride-height sensor and expose line up to engine carrier
- If necessary, expose and disconnect vacuum line for engine mount up to point of separation on engine support arm
- Except M5, M6: Disconnect pressure line(s) from vane pump. See REMOVING AND INSTALLING (REPLACING) POWER STEERING PUMP FOR POWER STEERING GEAR WITH ACTIVE FRONT STEERING , REMOVING AND INSTALLING POWER STEERING PUMP FOR POWER STEERING GEAR WITH DYNAMIC DRIVE (N54) , or REMOVING AND INSTALLING/REPLACING VANE PUMP FOR POWER STEERING (N54) . Refer to PUMP AND OIL SUPPLY .
- M5, M6: Disconnect pressure line from POWER STEERING GEAR . Also see PUMP AND OIL SUPPLY .
- Disconnect RETURN LINE FROM POWER STEERING COOLER
- Remove both STABILIZER LINKS FROM SPRING STRUT BRACKET
IMPORTANT:
- Check sensor head and line from pulse generator prior to installation for external damage, replacing if necessary.
Version with Dynamic Drive:
Remove BOTTOM RIGHT WHEEL ARCH TRIM .
Release nuts (1, 2).
Tightening torque (1): 32 41 3AZ .
Tightening torque (2): 37 14 13AZ .
Version with active steering:
Disconnect plug connections (1, 2).
Expose wiring harness (3) up to front axle carrier.
IMPORTANT:
Guide spring struts with your hand when lowering and raising in order to avoid damaging the wheel arches.
After lowering, the spring struts must be aligned to the front axle carrier and secured in such a way that the ball joints of the control arms, tension struts and tie rod ends are not damaged.

Remove both SPRING STRUTS FROM SPRING STRUT DOME .
Support FRONT AXLE CARRIER , release from engine carrier and carefully lower with spring struts.
After installation:
- Fill and bleed hydraulic system. See BLEEDING POWER STEERING (VERSION WITH DYNAMIC DRIVE) or BLEEDING POWER STEERING UNIT .
- Check pipe connections for leaks
- Carry out wheel alignment check if a spring strut with support bearing was or has been installed without centering pin. See ALIGNMENT CHECK WITH LOAD UP TO DESIGN POSITION or ALIGNMENT CHECK WITH RIDE-HEIGHT MEASUREMENT WITHOUT LOAD .
- Carry out steering angle sensor adjustment/adjustment for active steering. See ADJUSTMENT FOR ACTIVE FRONT STEERING and CARRYING OUT STEERING ANGLE SENSOR ADJUSTMENT
- If necessary, carry out INITIAL DYNAMIC DRIVE OPERATION
