A used OEM Audi ABS Wheel / Speed Sensor Wiring Conduit, part number 4B0971821, is a genuine component removed from a donor vehicle. This left-rear conduit protects the wiring for the wheel speed sensor on models like the A6 Quattro, Allroad Quattro, RS6, and Passat. It accommodates multiple engine configurations, including the 2.7L and 4.2L turbocharged variants. When this plastic housing is damaged or broken, exposed wires can lead to intermittent ABS or traction control faults.
