Vemo V10-72-1239 Sensor, wheel speed

Vemo V10-72-1239 Wheel Speed Sensor

The Vemo V10-72-1239 is a high‑performance wheel speed sensor designed for modern automotive safety systems. It delivers precise rotational data to the vehicle’s ABS (Anti‑Lock Braking System), ESP (Electronic Stability Program), and other traction control modules, ensuring optimal braking performance and vehicle stability under all driving conditions.

Key Functionalities

• Accurate Speed Measurement: Provides real‑time wheel speed data with minimal latency, enabling the ABS to modulate brake pressure accurately during lock‑up scenarios.
• High Reliability: Built with robust materials and a sealed design that protects against moisture, dust, and vibration—critical for long‑term durability in harsh operating environments.
• Compact Size & Low Profile: Its slim form factor allows seamless integration into tight mounting spaces commonly found on modern vehicles.
• Wide Operating Temperature Range: Functions reliably from –40 °C to +120 °C, covering the extremes encountered in both cold climates and high‑performance driving.

Technical Specifications

Vehicle Compatibility

The Vemo V10-72-1239 is engineered to fit a wide array of vehicles, particularly those from the Audi A4 8E2 B6 family and other VAG (Volkswagen Group) models. Its standardized connector and signal output make it suitable for:

• Front & Rear Axles: Both left and right wheel positions.
• Sedans, Hatchbacks, and Coupés: Including the A4 B6 sedan, A4 B6 hatchback, and A4 B6/B7 Cabriolet variants.
• Other VAG platforms such as the Volkswagen Golf, Polo, and Audi Q3.

Installation Guidelines

1. Safety First: Disconnect the vehicle’s battery to prevent accidental electrical discharge.
2. Remove Existing Sensor: Carefully detach the old wheel speed sensor from its mounting bracket, noting the orientation and wiring harness connections.
3. Mount the V10-72-1239: Align the new sensor with the mounting holes and secure it using the supplied fasteners. Ensure that the sensor’s magnetic field aligns correctly with the wheel’s rotating element (usually a toothed disc or magnet).
4. Reconnect Wiring: Plug the sensor’s connector into the vehicle’s harness, verifying correct pin alignment to avoid signal loss.
5. Test Functionality: Reconnect the battery and start the engine. Use an OBD‑II scanner or a dedicated wheel speed diagnostic tool to confirm that the sensor outputs accurate pulse rates corresponding to wheel rotation.
