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.
Starter Control: Notes
EWS III plus is used in the E83. The basic function of starter control and enabling of DME and EGS has remained the same. With EWS III plus the terminal 50 information is forwarded not from the starter motor but rather directly from the EWS control unit to the instrument cluster. A circuit is hard-wired from the output of the starter relay in the EWS III plus control unit directly to the instrument cluster. In order to avoid erroneous measurements, no sensor values are stored during the starting process.
