Why Volkswagen Cruise Control Not Working

Cruise Control Switch Malfunction

The cruise control switch is a mechanical or electronic switch that is used to engage and disengage the cruise control system. If the switch is malfunctioning, it can cause the cruise control to not work properly.

Cruise Control Throttle Position Sensor Malfunction

The cruise control throttle position sensor (TPS) sends a signal to the cruise control computer about the position of the throttle. If the TPS is malfunctioning, it can cause the cruise control to not work properly.

Cruise Control Brake Switch Malfunction

The cruise control brake switch is a switch that is used to disengage the cruise control system when the brakes are applied. If the brake switch is malfunctioning, it can cause the cruise control to not work properly.

Cruise Control Computer Malfunction

The cruise control computer is a computer that controls the operation of the cruise control system. If the cruise control computer is malfunctioning, it can cause the cruise control to not work properly.

Cruise Control Wiring Malfunction

The cruise control system is wired to various components in the vehicle. If the wiring is damaged or corroded, it can cause the cruise control to not work properly.

How to Troubleshoot: Volkswagen Cruise Control Not Working

Overview

Cruise control is a convenient feature that can help you to maintain a steady speed on long road trips. However, if your Volkswagen cruise control is not working, it can be a major inconvenience. There are a few different things that could be causing the problem, and troubleshooting the issue can be relatively simple.

Possible Causes

There are a few different things that could be causing your Volkswagen cruise control to not work. Some of the most common causes include:

A faulty cruise control switch. The cruise control switch is located on the steering wheel, and it is responsible for sending signals to the cruise control system. If the switch is faulty, it may not be able to send the correct signals, which could prevent the cruise control from working.
A faulty cruise control module. The cruise control module is responsible for controlling the cruise control system. If the module is faulty, it may not be able to properly regulate the speed of the vehicle, which could prevent the cruise control from working.
A faulty brake switch. The brake switch is located on the brake pedal, and it is responsible for telling the cruise control system when the brakes are applied. If the brake switch is faulty, it may not be able to properly communicate with the cruise control system, which could prevent the cruise control from working.
A faulty throttle position sensor. The throttle position sensor is responsible for telling the cruise control system how much throttle is being applied. If the sensor is faulty, it may not be able to properly communicate with the cruise control system, which could prevent the cruise control from working.

Troubleshooting Steps

If your Volkswagen cruise control is not working, you can try troubleshooting the issue by following these steps:

1. Check the cruise control switch. The first thing you should do is check the cruise control switch to make sure that it is turned on. The switch is usually located on the steering wheel, and it should be in the On position.
2. Check the brake switch. The next thing you should do is check the brake switch to make sure that it is working properly. The brake switch is located on the brake pedal, and it should be in the On position when the brakes are applied.
3. Check the throttle position sensor. The throttle position sensor is located on the throttle body, and it should be sending a signal to the cruise control system. You can check the sensor using a voltmeter. If the sensor is not sending a signal, it will need to be replaced.
4. Check the cruise control module. The cruise control module is located under the dashboard, and it is responsible for controlling the cruise control system. You can check the module using a diagnostic tool. If the module is faulty, it will need to be replaced.
