Where is the crankshaft position sensor located on the Audi A6L 2.5?

[JulietteDella]

The crankshaft position sensor on the Audi A6L 2.5 is located inside the distributor, below the oil filter. Function of the crankshaft sensor: The role of the crankshaft position sensor is to determine the position of the crankshaft, specifically its rotation angle. It typically works in conjunction with the camshaft position sensor to establish the basic ignition timing. The engine's ignition timing and which cylinder fires rely on signals from the crankshaft position sensor, as it detects when the piston reaches top dead center. Symptoms of a faulty crankshaft sensor: If the crankshaft position sensor is damaged, the rotation angle of the crankshaft cannot be determined. The engine control unit (ECU) will not receive signals from the crankshaft position sensor, leading to a protective shutdown—no ignition, no fuel injection, and the car failing to start. The most obvious symptom is the illumination of the engine warning light on the dashboard.
