Detailed Description

Delphi SS20555 is engineered for front wheel speed sensing on BMW xDrive and xi models listed in the fitment data. As an ABS wheel speed sensor, it monitors wheel rotation and sends the signal needed by the anti-lock braking system to manage braking response. Delphi validates its sensors to OE standards, which supports accurate signal output and dependable service life in everyday driving conditions. If you are replacing a worn or failed BMW ABS sensor, SS20555 provides a direct replacement path for the front position.

This part cross-references Standard Ignition ALS1830 for the same application.

What It Helps Solve

• ABS warning light illuminated
• Wheel speed signal loss or erratic readings
• Traction control or stability system faults tied to wheel speed input
• Brake system fault codes related to the front sensor circuit
• Intermittent ABS operation caused by a failing front sensor

Installation Notes and Tips

• Verify the front position and connector style before installation.
• Inspect the harness routing and connector condition during replacement.
• Confirm the sensor seating surface is clean before installing the new unit.
• Use the included instruction sheet as a reference during service.
• After installation, clear fault codes and road test the vehicle to confirm proper operation.

Quality Assurance

Delphi backs its sensor portfolio with OE-focused development and product validation methods. SS20555 is tested and calibrated to OE standards to support accurate readings and consistent braking system input.
