Standard Ignition ABS Wheel Speed Sensor P/N:ALS451
Keep your ABS and traction control reading wheel speed accurately with the Standard Ignition ABS Wheel Speed Sensor ALS525. It installs as a direct-fit replacement for the 2000 Audi A4 Quattro [All] and the 2000-2001 Audi S4 [All], and was tested on-vehicle for proper fit and correct integration with the electronic safety systems.
The ABS wheel speed sensor monitors the rotation of its wheel and relays that signal to the ABS and traction/stability control systems so they can modulate braking and manage grip. If a failed wheel speed sensor is the cause of an illuminated ABS or traction control warning light, or of an intermittent wheel-speed signal, this replaces it. Mounts at the wheel; the listed applications use one per location. Country of origin: Germany.
