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.

The starter control takes over the actuation of the starter (M1) and interrupts the circuit (circuit 50) to the solenoid switch of the starter (starter deactivation) after reaching the engine cranking speed.
By actuating the ignition starter switch at the electronic ignition switch control unit (N73), from position "2" (ignition ON) in position "3" (START), starter detection is performed by the ME control unit (N3/10).
The solenoid switch of the starter is actuated by the ME control unit via the starter relay.
The voltage supply of the starter relay (coil) is supplied through circuit 87. The starter relay is actuated by the ME control unit with a ground signal.
If the starting procedure has started, the actuation of the ignition starter switch from position "3" back into position "2" no longer has any influence (touch start).
When reaching the engine cranking speed of 400 up to 700 rpm or a starting time of approx. 5 to 40 seconds (dependent on the engine temperature), the ME control unit interrupts the negative activation to the starter relay and therefore ends the starting procedure.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
