Product Details

HELLA’s brake sensor line focuses on accurate wheel speed detection for ABS-equipped vehicles. This sensor monitors wheel movement so the control system can respond correctly during braking events. For BMW 528i xDrive and BMW 535i xDrive front wheel applications, the correct signal from the wheel speed sensor is essential for consistent ABS performance and predictable braking behavior. Part number 012806421 is specified for select 2006-2010 BMW models and matches the listed front axle positions.

This part cross-references Febi-Bilstein 47809 and Standard Ignition ALS1835 for the same application.

What It Helps Fix

  • ABS warning light caused by a failed front wheel speed sensor
  • Loss of wheel speed signal at the front axle
  • Erratic ABS activation during braking
  • Traction or stability control faults tied to wheel speed input
  • Brake system performance issues on select BMW xDrive models
