Keep fuel delivery and ignition timing properly synced with the Standard Ignition Engine Camshaft Position Sensor, part number PC671. Cataloged for the left camshaft position, it installs as a direct-fit replacement for the listed Audi applications, including the 2003-2005 Audi Allroad Quattro, the 2004-2009 Audi S4, and the 2006-2007 Audi A4.
The camshaft position sensor gives the ECM a reference for where the camshaft is, which the module uses for sequential fuel injection and spark timing. Signs this part may need replacing include hard starting, stalling, rough running, or an illuminated check engine light with a camshaft position sensor code. Because those symptoms can have other causes, diagnose the fault first; if a failed camshaft position sensor is the cause, this replaces it.
