Are you looking for a way to turn off the check light that is glowing on your Audi? If yes, we can show you how. The sudden illumination of this warning light is very scary especially when you are not sure what could have made it come on. Whether the cause of illumination is just a loose gas cap or even a faulty sensor, the check light is your Audi’s way of telling you it needs attention.
The good news though is that once the cause of a warning light is addressed, the process of resetting the light is relatively easy. Let’s look at some of the common reasons why the light comes on, how you can clear it, and where you should go if you want the problem fixed accurately.
Possible Causes of the Check Engine Light
Before jumping into how to reset the check light, it’s important to know some of the common reasons why it might come on in the first place:
- Loose or Missing Gas Cap: A loose or missing gas cap is one of the reasons why an automobile gives a check light. This may sound almost ridiculous, but you have to remember that any space in the gas cap can lead to a drop in the pressure of the fuel system, and whenever your Audi notices a drop in fuel pressure it triggers the light.
- Oxygen Sensor Issues: The duty of the oxygen sensor is to check unburned oxygen in the exhaust system. If it’s not working as expected, it leads to poor fuel economy and emissions problems.
- Catalytic Converter Problems: If your catalytic converter is not working well then your check light may turn on.
- Faulty Spark Plugs or Ignition Coils: Ignition systems include spark plugs and coils and their job is to ignite the air/fuel mixture inside your engine. The light can be triggered when any of the components in the ignition system goes bad.
How To Go About Resetting Your Check Engine Light
Once you’ve resolved the issue that triggered your Audi’s check light, resetting it is simple:
- Use an OBD-II Scanner: The best and simplest device that can be used to clear the check light is an OBD-II scanner. It reads the error codes after being connected to the diagnostic port and also enables one to erase them after reading. This tool is cheap and can be found in almost any store, or you can go to a mechanic and use theirs.
- Disconnect the Battery: Another way is to remove the negative terminal of the battery of your Audi for about 10 This removes the fault codes in the car’s computer and consequently shuts down the check light. Note, however, that it will also revert your car back to its default factory settings.
- Drive the Car: In some cases such as a loose gas cap, the check engine may go off after a few driving cycles. Driving a car for one or two days helps the system to re-evaluate and maybe correct the errors.
Although the above steps may sound easy to perform, one needs to understand that simply resetting the check light is not a good thing to do, as what is more important is to actually solve the issue behind the light. Ignoring the cause and just resetting the light is very dangerous because it can lead to big engine troubles or unsafe driving circumstances.
