DTC P1377, BMW Hex Code 0x2B66, BMW Code 11110: Camshaft Position Sensor Master Camshaft not Defined (SIG): Remarks

No remaining NWG is available to assume the role of master. At least one NWG is needed to calculate the engine's current position. If the last remaining NWG fails while the engine is running, it remains possible to calculate the engine's position using the KWG. Once the engine is off, it is not possible to restart it.
