Rear ABS Wheel Speed Sensor for BMW F45 F46 F48 and MINI F54 F55 F56

1. OE Cross-Reference and Platform Fitment

The KU-FV-03-011 is a rear ABS wheel speed sensor for compatible BMW and MINI vehicles built on the UKL front-wheel-drive platform. It corresponds to current OE number 34526858467 and replaces the earlier OE number 34526850764.

• BMW 2 Series Active Tourer F45
• BMW 2 Series Gran Tourer F46
• BMW X1 F48
• MINI Clubman F54
• MINI Hatch 5-Door F55
• MINI Hatch 3-Door F56
• Current OE: 34526858467
• Previous OE: 34526850764

Vehicle compatibility should be confirmed using the OE number, chassis code, production date and original connector before ordering.

2. ABS and DSC Signal Function

The active sensor measures rear-wheel rotational speed and sends the signal to the vehicle’s ABS and DSC control systems. Accurate wheel-speed information allows the corresponding control unit to compare wheel movement and manage braking or stability functions when required.

• Wheel-Speed Measurement: Detects rotational movement at the rear wheel.
• ABS Signal Input: Supplies speed data to the anti-lock braking control system.
• DSC System Support: Provides wheel-speed information used by the stability-control system.
• Continuous Signal Transmission: Maintains communication while the vehicle is moving.
• Fault Repair Application: Can restore the wheel-speed signal when the original sensor is the cause of an ABS or DSC fault.

3. Left and Right Rear Installation

The same OE sensor configuration is used on both rear-wheel positions. This simplifies workshop inventory because one part number can be stocked for either installation side.

• Rear-left installation
• Rear-right installation
• One sensor per wheel
• Identical OE number for both sides
• Direct connection to the corresponding rear wiring interface

Each package contains one sensor. Two sensors are required when replacing both rear-wheel sensors.

4. Sensor and Cable Construction

The sensor assembly combines an active sensing element, molded connector and flexible cable harness. Its nitrile-rubber outer jacket is designed for repeated suspension movement and exposure to common road contaminants.

• Active Sensor Design: Provides electronic wheel-speed signal output.
• NBR Cable Jacket: Supports flexibility and resistance to temperature changes.
• Sealed Connector: Helps protect the electrical contacts from water and dirt.
• Flexible Harness: Accommodates wheel and suspension movement during driving.
• Vehicle-Specific Retaining Points: Follow the corresponding original cable-routing positions.
• Corrosion-Resistant Structure: Helps withstand wet roads, mud and winter road conditions.

5. Diagnostic and Replacement Value

A faulty wheel speed sensor may cause an ABS or DSC warning light, interrupted wheel-speed data or incorrect operation of related control functions. Replacing the failed sensor with the corresponding OE-matched part can restore signal communication when the sensor is confirmed as the source of the fault.

• Wheel-speed signal inspection
• ABS warning-light diagnosis
• DSC fault repair
• Rear-hub service
• Suspension and brake repair
• OE-based workshop replacement
• Automotive aftermarket distribution
