What’s Wrong
The excess length of the wiring harness to the engine control unit could result in a faulty camshaft signal. This faulty camshaft signal may lead to an unintentional cancellation of the automatic starting procedure after automatic engine stop of the automatic start/stop system. In the event of a faulty camshaft signal the engine would not restart as expected following the stop procedure but can be manually restarted immediately by engaging the transmission selector lever position ,N, or ,D, and by operating the ignition key or the start button (with keyless go). Depending on the traffic situation however an increased accident hazard could result.
