A genuine Audi rear bumper wiring harness, OEM number 8U0971104AC, also superseding 8U0971104AA. This used harness was removed from a donor Q3 and routes power and signals for taillights, license plate lights, and parking sensors. It fits both gasoline and diesel models with the 1.4L and 2.0L turbocharged gas or 2.0L diesel engines. A damaged rear harness commonly causes intermittent tail light operation or complete sensor failure.
