Some Mini Cooper owners report experiencing intermittent engine stalling and tachometer fluctuations, which may be attributed to a faulty crankshaft position sensor. Symptoms of this issue can include engine hesitation during acceleration, car shaking while idling, and difficulty starting the vehicle. Additionally, owners may notice the Check Engine Light illuminating, indicating potential problems. A faulty crank sensor can lead to rough idling, vehicle misfiring, and vibrations, ultimately resulting in stalling or starting difficulties. To diagnose the issue, it is recommended to use an OBD-II scanner to check for the P0335 code, inspect the sensor and its wiring for any damage, and replace the sensor if necessary. Prompt attention to these symptoms is crucial to prevent further complications and ensure the smooth operation of the Mini Cooper.
