Porsche Cayenne 3.6 957 Starter Motor 012911023 G - Used Original Parts

Diagnosis and Common Symptoms

From the workshop floor, a failing starter motor on the Porsche Cayenne 957 with the 3.6L VR6 engine presents a distinct set of symptoms. The most common complaint is a "no crank, no start" condition. When the key is turned, you may hear a single, sharp "click" from the engine bay—this is the starter solenoid engaging but the motor itself failing to turn the flywheel.

Another key indicator is a slow, laboured crank, even with a fully charged and healthy battery. This signals high internal resistance within the starter's windings or worn bushings causing it to draw excessive current. Intermittent starting problems, where the vehicle starts perfectly one time and fails the next, also point directly to a deteriorating starter motor. While this fault typically does not trigger specific "Check Engine" lights, a diagnostic scan might reveal low voltage faults or errors related to the "Terminal 50" starter signal circuit due to the high amperage draw of the failing unit.
