Standard Ignition SC684 vehicle speed sensor for the 2004-2006 Volkswagen Phaeton and other vehicles sends a road-speed signal to the vehicle's computer. It is designed to support smooth transmission shifting and proper cruise control operation.
A failing speed sensor can show up as a speedometer that reads wrong or drops out, cruise control that will not hold, or shifts that feel off. Before you replace this sensor, look over its connector and wiring for damage and have a shop confirm the cause, since other problems can look the same.
The 2004-2006 Volkswagen Phaeton, the 1997-2003 Audi A8 Quattro and the 2003 Audi RS6 are among the vehicles this direct-fit replacement fits, at one sensor per vehicle. Driving something else? Look up your year and model in the "Vehicles it fits" section of this page.
