VW Blind Spot Monitoring Not Working (Solved)

VW blind-spot monitoring not working? This article will help explain everything that could have gone wrong and how you can correct it. The blind spot monitor system of the Volkswagen can detect vehicles up to a distance of 70 meters. However, this system can malfunction sometimes.

How Does VW Blind Spot Monitoring Work?

The blind-spot monitoring system is made using two radar sensors that are placed on the bumper’s rear corners. These can easily locate vehicles from up to 70 meters away. This also covers the blind spots on both sides of the car.

The blind-spot monitoring system of the VW has been designed to sense vehicles that one might miss from the naked eye. When changing lanes, this monitor alerts you regarding vehicles in your blind spot.

The blind spot may become a safety problem for drivers. This is more probable when the driver is either too tired or not focused enough on the road. This feature makes it easier to change lanes or turn a corner.

If some vehicles are approaching from the driver’s blind spot, they will be alerted using flashlights which are placed on the far ends of both side mirrors. If the driver continues to take a turn or change lanes despite the warning, the system begins steering the car in the opposite direction.

This helps prevent a collision. However, the driver can still have control over the vehicle by actively steering in order to override the system.

What are the Problems You Might Be Facing with the Blind Spot Monitoring?

Following are some of the problems that you might face with the blind-spot monitoring:

  • Turns Off Randomly:

The blind-spot monitoring of the VW might have a few hiccups, just like any other good electronic system. The system might turn off suddenly, leaving the user confused. This could be due to an older model or an internal wiring malfunction.

Despite the cause, a sudden error sign showing up on the screen while you are driving on the highway or the expressway can be very dangerous. The driver will not be able to tell whether there is a technical fault or if a driver is approaching from their blind spot.

  • Unreliable on Dirty Roads:

Dirty roads can cause blind-spot monitoring to malfunction. This is because mud or dust covers the car’s sensors that are responsible for signaling the monitor. This can be a major issue in areas with snow and mud.

  • System Doesn’t Turn On Automatically:

Another issue that drivers might face is that the monitoring system does not turn on when they start the car. It needs to be enabled manually.
