Mercedes Benz C350 ABS Wheel Speed Sensor in US

Your Mercedes Benz C350 ABS wheel speed sensor is the component that makes anti-lock braking possible on your C350. It monitors the rotational speed of each wheel in real time and sends that data to the Mercedes Benz C350 ABS control module, which uses it to prevent wheel lockup during emergency stops. When a sensor fails on your C350, your ABS loses the input it needs. On wet, icy, or gravel road surfaces, the difference between a controlled stop and a skid can come down to whether your Mercedes Benz C350 wheel speed data is reaching the module.

What Is the ABS Wheel Speed Sensor on Your Mercedes Benz C350

The ABS wheel speed sensor on the Mercedes Benz C350 is an electromagnetic or Hall-effect sensor mounted near each wheel hub or bearing assembly of your C350. It generates an electronic signal as a toothed reluctor ring rotates past it, producing a frequency the C350 ABS module interprets as wheel speed. On most modern Mercedes Benz C350 vehicles, this same data feeds the traction control system, electronic stability control, and electronic brake force distribution, making a functioning wheel speed sensor critical to the safe operation of multiple C350 systems simultaneously.

Signs of a Failing ABS Wheel Speed Sensor on the Mercedes Benz C350

• ABS warning light on your Mercedes Benz C350 dashboard, the most common first indicator of a failing sensor
• Traction control or stability control warning light illuminated alongside the C350 ABS light
• ABS activating on your Mercedes Benz C350 during normal stops at low speed where it should not engage
• Complete ABS deactivation on the C350, wheels lock under hard braking on wet or icy roads
• Speedometer on your Mercedes Benz C350 reading erratically or dropping to zero at speed
• Fault codes in the C0035 to C0050 range stored in the Mercedes Benz C350 ABS control module

Passive vs. Active ABS Sensors for the Mercedes Benz C350

GeoBrakes stocks both passive and active ABS wheel speed sensors for the Mercedes Benz C350. Passive sensors use an analog signal and are found on older C350 vehicles and many trucks still in service. Active Hall-effect sensors require a small power supply and output a clean digital signal, offering greater accuracy at very low speeds. Active sensors are standard on most Mercedes Benz C350 vehicles manufactured after the mid-2000s and are required for full compatibility with modern C350 traction and stability control systems.

Why GeoBrakes for the Mercedes Benz C350 ABS Wheel Speed Sensor

Signal accuracy matters as much as fitment with Mercedes Benz C350 wheel speed sensors. A sensor that generates the correct frequency for your C350 ABS module ensures consistent ABS calibration, proper traction control thresholds, and accurate stability control response on your Mercedes Benz C350. Every sensor in the GeoBrakes catalogue is matched to the Mercedes Benz C350 through our vehicle selector, with front and rear positions listed separately to eliminate position errors on your C350.

Frequently Asked Questions - Mercedes Benz C350 ABS Wheel Speed Sensor

Can I drive my Mercedes Benz C350 with a faulty ABS wheel speed sensor?

You can drive the Mercedes Benz C350 with a failed ABS sensor, but the anti-lock braking system on your C350 will be completely disabled. On icy or wet American roads, this significantly increases stopping distances and the risk of losing steering control during hard braking on your Mercedes Benz C350. Replacing a failed sensor promptly is strongly recommended, particularly before winter.

How do I find the right ABS sensor for my Mercedes Benz C350?

Use the GeoBrakes vehicle selector and enter the Mercedes Benz C350 year, make, and model. The system displays only the sensors confirmed to fit the Mercedes Benz C350, with front and rear positions listed separately. Select the position matching the sensor you are replacing on your C350 to avoid receiving the wrong unit.

Do I need to replace all four ABS sensors on my Mercedes Benz C350 at the same time?

No. ABS wheel speed sensors on the Mercedes Benz C350 are independent components and only the failed unit needs to be replaced. However, if your C350 has high mileage and one sensor has failed, it is worth visually inspecting the connectors on the other Mercedes Benz C350 sensors for corrosion while the wheel is removed.
