Let’s take a closer look
Inside the car, we can find the fuel selector switch. It’s the most visible part of the system, mounted in the dashboard. The colors are adaptable to your own preferences, and the LED indicators show how much LPG is in the tank and therefore how far you can drive before you need to refuel.
To switch from driving on LPG to petrol and reverse, you can push the fuel selector switch.
Under the hood
The fuel selector switch is not working on its own. It is corresponding with the LPG computer which is installed under the hood of this car. This computer can be considered ‘the heart of the system’. It ensures overall system control, and is connected to the other components of the system. The main components under the hood of the car are: the LPG reducer (eVP-500) which turns the liquid gas into vapor form, the filter unit to ensure the quality of the fuel, and the Keihin injectors to inject LPG into the engine.
In addition to these components under the hood, the LPG system also includes an LPG tank in the trunk of the car. This tank can (almost) always be installed in the spare wheel compartment, so you don’t lose any trunk space. The LPG tank in this Audi Q3 contains up to 55 Liter LPG, which results in a driving range of approximately 500 Kilometers.
The LPG tank can easily be filled via the adapter that is mounted next to the petrol filling point. Please be aware that there are several (4) different LPG adapters used worldwide. It is best to store all of them in your car. If you ever go traveling abroad, you might need to use another adapter. It is very easy, just twist it on, connect the LPG filling pistol and start refueling.
