Volkswagen Up ABS Wheel Speed Sensor in US

Your Volkswagen Up ABS wheel speed sensor is the component that makes anti-lock braking possible on your Up. It monitors the rotational speed of each wheel in real time and sends that data to the Volkswagen Up ABS control module, which uses it to prevent wheel lockup during emergency stops. When a sensor fails on your Up, 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 Volkswagen Up wheel speed data is reaching the module.

What Is the ABS Wheel Speed Sensor on Your Volkswagen Up

The ABS wheel speed sensor on the Volkswagen Up is an electromagnetic or Hall-effect sensor mounted near each wheel hub or bearing assembly of your Up. It generates an electronic signal as a toothed reluctor ring rotates past it, producing a frequency the Up ABS module interprets as wheel speed. On most modern Volkswagen Up 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 Up systems simultaneously.

Signs of a Failing ABS Wheel Speed Sensor on the Volkswagen Up

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

Passive vs. Active ABS Sensors for the Volkswagen Up

GeoBrakes stocks both passive and active ABS wheel speed sensors for the Volkswagen Up. Passive sensors use an analog signal and are found on older Up 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 Volkswagen Up vehicles manufactured after the mid-2000s and are required for full compatibility with modern Up traction and stability control systems.

Why GeoBrakes for the Volkswagen Up ABS Wheel Speed Sensor

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

Frequently Asked Questions - Volkswagen Up ABS Wheel Speed Sensor

Can I drive my Volkswagen Up with a faulty ABS wheel speed sensor?

You can drive the Volkswagen Up with a failed ABS sensor, but the anti-lock braking system on your Up 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 Volkswagen Up. Replacing a failed sensor promptly is strongly recommended, particularly before winter.

How do I find the right ABS sensor for my Volkswagen Up?

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

Do I need to replace all four ABS sensors on my Volkswagen Up at the same time?

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