When you see the P13B4 trouble code on a BMW, it means that the Engine Control Module (ECM) has detected an issue with the Crankshaft or Inlet Camshaft Position Sensor that is not within the normal range specified by the manufacturer. This could be due to a faulty sensor, damaged wiring to the sensor, or corrosion affecting the electrical connection between the sensor and the wiring. The first thing to do is to inspect the connection by unplugging it and ensuring there is no water or debris present. Check for any physical damage to the sensor as well. If everything looks fine, the next step is to replace the sensor. You can often find a replacement online at a lower cost compared to buying directly from BMW.
