Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Wiper Motor
The front wiper motor is a little smaller than the wiper motor in the E65.
Advantages of the wiper motor:
- Lighter
- Less noise
- Reversing wiper motor
- Stable wiper speed
- Reduced tendency of the wiper blades to judder
- Alternating rest position of the wiper blades.
The wiper motor has two speed settings for wiping the windscreen.
The wiper motor receives information about the wiper stage via the LIN bus. The LIN-bus messages are evaluated by electronics in the wiper motor.
A constant speed is generated by the electronics, enabling consistent wiping by the windscreen wipers.
The wiper motor stores the wiper arms, and therefore also the wiper blades, outside the field of vision, as in the E65. In addition, they are stored on alternate sides. This prevents unnecessary wear on the wiper blades and they will remain pliant for longer.
