Keep your Audi's factory parking assist working the way it should with the Standard Ignition Parking Aid Sensor (PPS14). This ultrasonic parking aid sensor mounts in the bumper and detects nearby obstacles while parking or maneuvering, feeding that signal to the vehicle's parking assist system so it can trigger the audible and/or visual warning. It is a direct-fit replacement for the listed applications, including the 2002, 2004-2005 Audi A4 and 2003-2006 Audi A4 and A4 Quattro, plus the 2002 and 2004-2006 Audi S4.
- Function: Ultrasonic sensor that senses obstacles behind or around the vehicle and reports to the parking assist system.
- Signs it may need replacing: Constant beeping, no warning tone, false alerts, or a parking assist warning light — diagnose the cause before replacing, as these symptoms can have other sources.
- Quantity varies by vehicle: Some listed applications use two sensors and others use four; sold individually, so order the count your vehicle requires.
If a failed parking aid sensor is the cause of your parking assist trouble, this replaces it. Interchange: Manufacturer part number PPS14.
