FAQs

Does this sensor work on the rear axle?

No, this specific part number (XABS1289) is designed exclusively for front axle placement.

What should I do if the sensor tip does not seat properly?

Clean the mounting hole in the hub of any rust or debris using a wire brush before attempting to seat the new sensor.

Is the cable length standard for my vehicle?

Yes, with a cable length of 638 mm and an overall length of 720 mm, it meets the specific factory requirements for the listed BMW and MINI models.

Do I need to replace both front sensors at the same time?

While not strictly required, it is often recommended to replace them in pairs to ensure even signal quality and timing across the axle.

What is the connector type?

This sensor uses a standard 2-pin oval connector.

Troubleshooting

ABS Warning light remains on after installation

Clear the fault codes using an OBD-II diagnostic scanner; many systems will not reset automatically.

Setup, Compatibility & Care

Before starting, ensure the vehicle is safely supported on jack stands.

  1. Compatibility: Verify your vehicle's OEM part number matches 34526850767 to ensure compatibility with the XABS1289.
  2. Installation: Remove the wheel and the brake caliper/disc assembly as needed to access the sensor mounting point. Carefully disconnect the 2-pin connector and replace the sensor, ensuring the 638 mm cable is routed exactly through the original factory clips to prevent rubbing or snagging during suspension movement.
  3. Care: Keep the sensor tip clean of metal filings and debris, as these can interfere with the magnetic sensing capability. Do not use excessive force when seating the sensor in the hub.
