What this part does
The starter is a high-torque electric motor designed to engage the engine flywheel and crank the internal combustion engine when the ignition is activated. It is mounted where the engine block meets the transmission bell housing. When the internal solenoid or motor windings fail, the vehicle will typically experience a no-crank, no-start condition, which is often accompanied by a single loud click or an unusually slow crank when the ignition button is pressed.

Before you order
Before replacing your starter, completely test the vehicle's battery voltage and carefully inspect the main engine ground straps. Corroded or broken ground cables are extremely common on modern BMW platforms and mimic the exact symptoms of a failed starter motor. Additionally, confirm whether your specific engine utilizes single-use aluminum starter mounting bolts, as these must be replaced with new hardware during installation to ensure proper torque and prevent snapping.
