Your ABS speed sensor on the front wheel sends a weak signal.
The functionality of your ABS is consequently impaired.
Solution steps
Check the anti-lock braking system speed sensor on the front wheel for damage and correct assembly (e.g. loose bolts/screws, cable outlets). Check the sensor disc on the front wheel for damage and correct assembly (e.g. secure connection to hub or brake disc). Check the distance between the ABS speed sensor and sensor disc on the front wheel (max. 1 mm) and adjust it using shim rings if applicable. If the problem persists, please contact your specialist dealer.
