Detailed Description

Delphi builds this ABS wheel speed sensor using OE development and product validation methods, with testing and calibration to OE standards. That focus on signal accuracy helps maintain consistent wheel speed data for the brake control system. The Delphi SS21506 is a direct-fit front left sensor for 2021-2023 Volkswagen Jetta, 2022-2023 Audi A3, 2022-2023 Audi A3 Quattro, 2022-2023 Audi Q3, 2022-2023 Audi S3, 2022-2023 Volkswagen Arteon, 2022-2023 Volkswagen Atlas, 2022-2023 Volkswagen Atlas Cross Sport, 2022-2023 Volkswagen Golf R, 2022-2023 Volkswagen GTI, 2022-2023 Volkswagen Taos, and 2022-2023 Volkswagen Tiguan. This part cross-references WHT 003 861 A for the same application.

What It Helps Address

• ABS warning light caused by a failed front left wheel speed sensor
• Erratic or missing wheel speed signal at the brake control module
• ABS activation concerns related to inaccurate sensor output
• Traction control or stability system faults tied to wheel speed data
• Brake system diagnostic trouble codes linked to the front left sensor circuit

Installation Notes

Verify connector style, terminal count, and front left position before installation. Inspect the tone ring, hub area, and wiring path for damage or contamination that could affect sensor readings. Use the included instruction sheet and confirm the sensor is fully seated and routed away from moving suspension components.

Quality Assurance

Delphi sensors are tested and calibrated to OE standards to support accurate readings and reduce comebacks. The SS21506 is a standard replacement ABS wheel speed sensor backed by Delphi's OE-focused development and validation process.
