Volkswagen Adaptive Cruise Control

Do you think your adaptive cruise control is malfunctioning in your Volkswagen? Adaptive Cruise Control, is a feature that provides driver assistance by automatically adjusting your vehicle’s speed to keep a large enough distance between the car in front of you and yourself. A Volkswagen ACC will maintain a safe speed and preset safe distance by slowing down the vehicle if the car ahead slows down for any reason or accelerates when traffic is speeding up around you.

At European Service Center, we see many different reasons for faulty or malfunctioning adaptive cruise controls. Some of the most common issues our technicians see are camera issues, sensor issues, system issues, and the environment. Signs we suggest looking out for are the warning light, erratic behavior, ACC functionality, an unavailable message, or sensor obstructions. If you believe your Volkswagen is having an adaptive cruise control fault, then bring it in immediately to our shop. Volkswagen recommends you get your ACC maintenance done every 40,000 miles.

Key Signs of an ACC Having Faults

These are the most common signs our mechanics notice when an ACC is causing problems:

Amber warning light

  • An amber warning light appearing on the dashboard, also with a message, is the primary indication that something is going on with your ACC.

Erratic behavior

  • Unexpected braking or sudden distance changes made between the vehicle in front of you indicate that a sensor is having issues.

No adaptive cruise control functionality

  • There is a potential problem with your ACC if the system doesn’t respond while trying to activate it.

“ACC Unavailable” message

  • The message ACC Unavailable usually means there is a fault because the system is not active.

Sensor obstructions

  • Check the radar sensor in the front bumper for snow, bugs, dirt, or debris because it can interfere with the function of your ACC.

What is Causing my Volkswagen’s Adaptive Cruise Control to Malfunction?

European Service Center has experts who can properly diagnose your Volkswagen’s ACC. An ACC can be faulty due to various issues, so let our experts handle things for you. Some of the most common adaptive cruise control problems include:

Camera-related issues

    • Camera malfunction
      • In specific Volkswagen models, the ACC needs to rely on cameras and radar sensors. If a camera or two were faulty, then this would lead to the ACC not working properly.

Sensor-related issues

    • Damaged radar sensor:
      • If you’ve had an accident or physical damage done to the vehicle, then the radar unit could be damaged and be causing malfunctions.
    • Obstructed radar view:
      • The radar’s view can be blocked if you have heavy dirt build-up or accessories like aftermarket parts or license plate frames.
    • Dirty radar sensor:
      • The sensor’s performance can be affected if snow, dirt, or insects are covering them.

System-related issues

    • Software glitches:
      • The ACC control module can experience software errors sometimes, and this leads to erratic behavior.
    • Calibration issues:
      • The calibration might be off within the adaptive cruise control system, so it may need to be recalibrated.
    • Wiring issues:
      • Signal transmissions could be interrupted if the wires connecting the sensor to the control module are corroded or damaged.

The Environment

    • Extreme temperatures:
      • The ACC system’s performance may be affected by extreme temperatures or very hot or cold weather.
    • Severe weather conditions:
      • The radar’s ability to locate objects correctly can be interfered with by fog, heavy rain, or snow.

Steps to Take if You Think It’s an ACC Problem

  • Clean the radar sensor:
    • You should clean the radar sensors regularly. A soft and damp cloth will remove debris and dirt from the sensor.
  • Check for obstructions:
    • Check for any obstacles around the sensor and the surrounding area too.
  • Check for warning lights:
    • If the ACC warning light starts displaying on your dashboard and you don’t know what could be going on, then check your owner’s manual to figure out what the cause is.
  • Have your vehicle checked by our qualified technicians:
    • If you complete the basic checks and cleaning but the problem is still happening, bring your Volkswagen to our shop where our technicians can diagnose and fix the issue.
