If your Volkswagen has a wheel speed sensor problem, it can cause the ABS (anti-lock brake system) and the traction control system to malfunction. This can reduce your ability to safely control the car in a skid and could reduce your braking ability while driving. Additionally, if the wheel speed sensor fails completely, your car’s cruise control and stability control systems may be affected. In extreme cases, your car may not start. As a result, it’s very important to address any wheel speed sensor problems with your Volkswagen as soon as possible.
