Where is the crankshaft position sensor on a 2003 Volkswagen Passat?

The crankshaft position sensor on a 2003 Volkswagen Passat is located on the left side of the engine, near the transmission. It is a small, black sensor that is attached to the engine block with two bolts. The sensor is responsible for detecting the position of the crankshaft and sending a signal to the engine control unit (ECU). The ECU then uses this signal to control the timing of the fuel injection and ignition.
