Keep the spark and fuel timing dialed in with the Standard Ignition Engine Crankshaft Position Sensor PC573 — the S4 sensor that drops in as a direct-fit replacement for a range of Audi V6 models. This crankshaft position sensor tracks the rotational speed and position of the crankshaft and reports that signal to the engine control module, which uses it to time ignition and fuel delivery. When the original sensor degrades, the result can be hard starting, stalling, intermittent misfire, or a check engine light — if a failed crankshaft position sensor is the cause, this unit replaces it.

  • Function: Monitors crankshaft position and speed and feeds that data to the ECM for ignition and injection timing.
  • Direct-fit replacement: A direct-fit replacement for the listed Audi applications.
  • May need replacing when: You experience no-start, rough running, stalling, or a stored crankshaft-position fault — diagnose the cause before replacing.

Fitment: 1995-1998 Audi A6 (V6-2.8L); 2000-2002 Audi S4 (V6-2.7L); 2001-2004 Audi A6 Quattro (V6-2.7L); 2001-2005 Audi Allroad Quattro (V6-2.7L); 2002-2004 Audi A6 Quattro (V6-3.0L). See the Buyer's Guide tab to confirm your exact vehicle and engine.
