Installation Notes and Tips

Confirm the vehicle’s front left or front right application before ordering, since this sensor is position-specific. Verify connector shape, terminal count, and harness routing against the original part, especially on Audi A6 Quattro models with 17in or 18in wheels. Use the included instruction sheet during installation and inspect the mounting area and wiring path for damage before final assembly.
