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.
Wash/Wipe System: Introduction
The wash/wipe functions are available once Terminal R status is ON.
The windscreen wipers are driven by an electric motor with a reducer gear.
The wiper blades have a new method of attachment to the windscreen-wiper arm.
The wash/wipe system no longer has ball-and-socket type washer jets. Instead, fan-type jets are used (fluidic jets).
The wash/wipe system is controlled by the body basic module (KBM). The washer-jet heater system is an
exception, however, as it is controlled by the automatic heating and air-conditioning module (IHKA).
The BMW 5 Series and BMW 6 Series are equipped with a rain-light sensor as standard. This makes automatic mode for the windscreen wiper generally possible.
