The 2219050201 Wheel Speed Sensor is a precision-engineered electronic component specifically designed for the rear axle of Mercedes-Benz CL-Class C216 coupe and S-Class W221 sedan models. This sensor, also known as an ABS sensor or anti-lock braking system speed sensor, is mounted at each rear wheel hub and continuously monitors individual wheel rotational speed . It transmits real-time data to the vehicle's Anti-lock Braking System (ABS), Electronic Stability Program (ESP), and traction control modules. As a direct OE-grade replacement, this sensor restores accurate speed signal acquisition, ensuring optimal safety system performance and proper drivetrain management for these flagship Mercedes-Benz vehicles covering model years 2005 to 2014

• OEM Direct Fitment: Engineered to replace original part number 2219050201, designed exclusively for Mercedes-Benz CL-Class C216 (2007-2014) and S-Class W221 (2005-2013) models, including sedan and coupe body styles .

• Active Sensor Technology: Utilizes active Hall-effect magnetic sensing technology to generate clean, consistent wheel speed signals at both low and high rotational speeds, ensuring accurate readings across all driving conditions .

• Rear Axle Placement: Specifically designed for rear wheel installation, with placement on the rear axle to provide precise speed monitoring for the vehicle's rear braking and stability systems .

• 2-Pin Oval Connector: Equipped with a 2-pin male terminal connector featuring an oval-shaped connector interface, ensuring a secure, weather-resistant electrical connection to the vehicle harness .

• Optimized Cable Length: Features a wiring harness length of approximately 675-690mm, designed specifically for the W221 and C216 chassis for proper routing and secure connection to the vehicle's electrical system .

• Direct Bolt-On Mounting: Designed with a bolted mounting type and 30mm fitting depth for secure attachment to the wheel hub or steering knuckle, requiring no modifications for installation .

• Comprehensive Vehicle Coverage: Compatible with a wide range of models including CL550, CL600, CL63 AMG, CL65 AMG, S350, S400 Hybrid, S550, S600, S63 AMG, and S65 AMG across multiple engine variants .

• Cross-Reference Compatibility: Replaces multiple OE numbers including 2215400917, A2215400917, A2219050201, and various aftermarket equivalents for broad application coverage .

• Eliminates ABS and ESP Warning Lights: A faulty wheel speed sensor is one of the most common causes of illuminated ABS, ESP, or traction control warning lights on Mercedes-Benz W221 and C216 models. Replacing it with this high-quality sensor clears error codes and restores full safety system functionality .

• Restores Critical Safety Systems: Without accurate wheel speed data, the ABS cannot modulate brake pressure during emergency stops, and the ESP system cannot detect wheel slip or yaw movement. This replacement restores these essential safety features, ensuring your Mercedes-Benz performs as engineered .

• Specifically Compatible with High-Performance AMG and V12 Models: Unlike universal sensors, this unit is calibrated for the specific tone ring design and signal voltage requirements of the W221 S-Class and C216 CL-Class, including the M275 V12 biturbo, M156, M157, M273, M278, and M285 engine variants. Covers AMG models including CL63 AMG, CL65 AMG, S63 AMG, and S65 AMG .

• Premium Brand Options Available: Available from leading manufacturers including ATE, FEBI BILSTEIN, Bremi, Vemo, and Intermotor, offering OE-quality performance with proven reliability and warranty coverage. ATE sensors are identical in fit, form, and function to original equipment supplied to auto manufacturers worldwide .

• Prevents Transmission and Drivetrain Issues: Many Mercedes-Benz models use wheel speed sensor inputs for transmission shift logic and drivetrain management. A failed sensor can cause erratic shifting, incorrect speedometer readings, or limp mode activation. This sensor resolves those issues.

• Easy Plug-and-Play Installation: Designed as a direct electrical connector fit with no need for programming, cutting, or soldering. The sensor plugs directly into the existing body-mounted ABS harness, saving diagnostic and installation time for professional mechanics and experienced DIY users .

• Durable Construction for Long Service Life: Manufactured with high-quality thermoplastic housing and premium internal components, offering excellent heat resistance, impact resistance, and protection against brake dust, moisture, and road contaminants in harsh underbody conditions .
