• Compact Form Factor: Its small footprint allows seamless integration into tight engine bay spaces without compromising airflow or cooling.

Technical Specifications

Compatibility and Applications

The TRW GBS2502 is engineered to fit a wide array of vehicles across multiple manufacturers:

• Volkswagen – Passat B5 GP, Golf, Jetta, and other models.
• Audi – A4, A6, Q3, and related platforms.
• Skoda – Octavia, Superb, Rapid, and similar series.
• Other OEMs – Compatible with vehicles that require a standard wheel speed sensor for ABS/ESP systems.

Its universal mounting design allows easy replacement of original sensors or integration into aftermarket braking upgrades without extensive modifications.

Installation Overview

1. Remove the Existing Sensor: Detach the wheel hub, unscrew the sensor bracket, and carefully disconnect the wiring harness.
2. Prepare the New GBS2502: Align the sensor with the mounting holes on the new bracket. Ensure that the magnetic field aligns precisely with the wheel’s rotating element.
3. Secure the Bracket: Fasten the bracket to the hub using the supplied bolts, tightening to manufacturer specifications.
4. Reconnect Wiring: Attach the sensor’s connector to the vehicle’s harness, ensuring a firm and secure connection.
5. Test Functionality: Verify that the ABS system recognizes the new sensor by checking diagnostic codes or performing a brake test. The sensor should produce a clear pulse train corresponding to wheel rotation.

Performance Benefits

• Enhanced Safety: Accurate wheel speed data allows the ABS module to prevent wheel lockup during emergency braking, maintaining steering control.
• Improved Reliability: The sensor’s passive design and robust construction reduce failure rates compared to active sensors that rely on external power.
• Low Maintenance: With minimal electrical consumption and durable materials, the GBS2502 requires little upkeep over its lifespan.
• Versatility: Suitable for both OEM installations and aftermarket performance packages, making it a preferred choice among automotive technicians.
