What are the symptoms of a faulty wheel speed sensor in a Volkswagen?

Once the wheel speed sensor is indeed damaged, it will not only cause a certain deviation in the speed display on the dashboard but also lead to unstable engine idling and reduced acceleration performance. Here is the relevant introduction: Hazards: It is very likely to experience momentary pauses or even complete stalling, which directly affects driving safety to some extent. Overall, the impact of a damaged wheel speed sensor is relatively severe, so when the wheel speed sensor malfunctions, it is essential to repair or replace it promptly. Notes: A faulty wheel speed sensor still allows the vehicle to continue driving, but it is best to drive at a relatively slow speed to the nearest auto repair shop for maintenance or replacement. After all, a faulty wheel speed sensor directly affects the vehicle's safety systems (such as ESP, ABS, etc.), leading to a decline in the car's stability performance.
As an automotive enthusiast who frequently tinkers with cars, a faulty Volkswagen wheel speed sensor can cause several annoying symptoms. The ABS light will stay illuminated continuously, and sometimes the traction control icon flashes, indicating the system has detected inconsistent wheel speeds. The speedometer may become inaccurate, suddenly dropping to zero or lagging, while the odometer stops accumulating mileage. During hard braking, the ABS may activate erroneously with abnormal pedal pulsation, posing greater risks on slippery surfaces where skidding or loss of control becomes more likely. Occasionally, the engine light may illuminate at startup, and associated electronic system failures increase the probability of skidding during turns. From my personal experience, the sensor's location is prone to dirt accumulation or corrosion, leading to signal interference. I recommend promptly reading diagnostic codes, cleaning the mounting points, and replacing the sensor if necessary—don’t delay, as safety comes first.
