Womala Front Left ABS Wheel Speed Position Sensor OE 1635421818 for Mercedes Benz
The Front Left ABS Wheel Speed Position Sensor (OE: 1635421818) is a core electronic component of the anti-lock braking system (ABS) for specific Mercedes Benz ML models. Installed on the front left wheel hub, it detects the wheel’s rotational speed and transmits real-time signals to the ABS control module. As an OE-grade part, it meets Mercedes Benz’s strict standards for signal accuracy, environmental resistance, and durability, ensuring reliable operation across driving conditions (e.g., wet roads, dusty environments, high-speed travel).
Constructed from high-performance materials: the sensor housing uses corrosion-resistant and impact-resistant plastic (to withstand road debris and harsh weather), while the internal sensing element is sealed to prevent damage from moisture, oil, or dust, ensuring stable signal transmission.
Core Functions
- Speed Detection: The primary function is to monitor the front left wheel’s rotational speed, providing precise data to the ABS control module.
- ABS Activation Support: Enables the ABS system to detect wheel lock-up during braking, adjusting brake pressure to maintain traction and prevent skidding.
- Vehicle Stability Assistance: Works with other safety systems (e.g., ESP) to enhance vehicle stability, especially in emergency braking or slippery road conditions.

| Mercedes Benz Model | 163154 ML 320 163157 ML 350 163175 ML 500 163113 ML 270 CDI 163128 ML 400 CDI |
Notes: This Front Left ABS Wheel Speed Position Sensor is model-specific and designed exclusively for the listed Mercedes Benz ML models. Do not use it for other models or variants to avoid issues like inaccurate speed signals, ABS system malfunctions, or illuminated warning lights. During installation, ensure the sensor is aligned correctly with the wheel hub’s tone ring and that the electrical connector is firmly plugged in to avoid signal loss. Periodically check the sensor for signs of failure such as ABS warning lights, inconsistent braking performance, or physical damage (e.g., cracks, wire fraying), and replace it immediately if faults are found to maintain the vehicle’s braking safety.
