大众宝来后轮ABS传感器 4B0927807 单独线束设计替换

When your Bora experiences wet-surface or low-speed braking with ABS warning on, paired with wheel lock or abnormal pedal feel, this indicates aging rear ABS sensor or signal miscalibration failing to transmit wheel speed data accurately. The sensor monitors wheel speed and transmits signals to the ABS control unit to prevent wheel lock in emergencies and maintain steering capability. This product OEM number is 4B0927807, fits Volkswagen Bora (2001-2008) and some platform-mate models. Installation note: sensor uses a separate wiring harness; ensure harness routing does not interfere with moving parts and clean mounting holes to avoid signal interference.
