Your vehicle’s airbag is one of the most important safety features in your Volkswagen. If your Volkswagen’s airbag light illuminates and stays off, it is often an indicator of a problem. This means that you may not be able to count on all the safety features in your car.
While it’s the last thing you would expect to experience, Volkswagen has had to call back some of their vehicles for airbag malfunctions. Let’s look at some of the main causes of this common Volkswagen problem and who to consult to help you if you are in Chattanooga.
To better understand why your airbag light would turn on, let’s first discuss how it works. Airbags were invented to cushion a driver from the impact of a collision. In the event of an accident, a car often comes to a quick stop. This is whether the car hits a stationary object or another moving car.
Unfortunately, a person’s body continues to move forward even if the car hits something solid. The force of the impact of the collision can push a person into the steering wheel or windshield. The airbag in your Volkswagen is designed to prevent you from experiencing some of the trauma from the collision. This it does by spreading the force from the collision across its large surface. This ensures that no single part of your upper body bears all the force from an accident.
Your Volkswagen’s airbag also minimizes the effects of an accident by prolonging the split seconds that it takes for you to feel the impact of a collision. This reduces the effect of the impact when it finally reaches you. Once the airbag deploys fully, it is then designed to deflate, bringing your body’s speed to zero. Any car that qualifies with a high safety rating must have fully-functional airbags to protect its drivers and/or passengers.
The airbag light in your Volkswagen comes on briefly when you switch on your car. But in some cases, the airbag light fails to go off after the brief moment. This illuminated light is often the first sign of a problem.
Primary Causes of Airbag Sensor Illumination
The malfunction that causes the airbag light in your Volkswagen to stay on can be for a number of reasons. When this problem occurs, your airbags may not deploy in case of an accident. Below are some of the common causes of airbag lights staying illuminated on your dashboard:
- Sensor damage: The airbag in your Volkswagen works off information computed from sensors, including the one in your Volkswagen’s seat belt switch. So when you fail to fasten your seatbelt correctly the light might come on.
Your Volkswagen also has crash sensors that senses when your car hits an object or car, triggering the circuits that sets in motion the deployment of your airbags. These crash sensors could also be faulty as a result of a false trigger. In this case, your car may have hit something but not with enough force to deploy the airbags. The only way to correct the sensor during this situation is by resetting the sensors.
- Broken clock-spring: The clock-spring is a component in your Volkswagen’s airbag mechanism that sends electric current through the heating component. It then prompts the chemical reaction that fills the airbags with nitrogen gas. Given its role in the airbag deployment mechanism, when it breaks, there will be no current transfer, and the airbag will not deploy. This will cause the airbag light to stay on as a warning that it won’t deploy in case of an accident.
- Corrosion: This can be as a result of your car being in a flooded place where water finds its way into the car’s computer system. Water could also short the circuit that enables the airbag to launch. In this case, the electric components in your Volkswagen’s airbags will short circuit and cause the light to stay on.
