1. What is the 16706 Audi Code?

The 16706 Audi code, also known as P0322, signifies “Ignition/Distributor Engine Speed Input Circuit No Signal.” This code indicates the Engine Control Unit (ECU) is not receiving a signal from the crankshaft position sensor (G28). According to research from the Bosch Automotive Handbook, 10th Edition, the crankshaft position sensor is critical for engine timing and fuel injection. This lack of signal can lead to various engine performance issues, primarily affecting the vehicle’s ability to start and run correctly.

  • Definition: The 16706 code indicates a fault in the crankshaft position sensor circuit, leading to a lack of signal to the ECU.
  • Importance: This sensor is vital for engine timing, fuel injection, and overall engine management.
