Coasting mode (in German freilauf) is a technology being used by the VAG group which is mostly available in their TSI BlueMotion models equiped with a DQ200 DSG. These models are more focussed on fuel economy. This new technology mimics the driver hybrid-style characteristics: lift off the throttle, and the car can coast with the engine completely deactivated. Compared to the previous system this new coasting mode reduces fuel consumption by up to 0.4 litres/100km.
What coasting mode does it disengage the engine from the gearbox, and shuts off the engine completely. This system is seamless and it goes automatically into coast mode whenever you lift your foot off the throttle pedal, most of the time you will not even know you are in coasting mode.
There are certain criteria for using this technology.
These days many manufacturers of cars are solely focused on efficiency, fuel economy, and meeting government emissions norms. In the future, we will experience more and more such technologies which will try to help to achieve these goals.
However, real-world experiences do teach us that not everyone is enthusiastic about these implementations. There are VAG users who absolutely don’t like this feature at all.
At the moment, we are not aware of any possibilities to turn this feature off in the car’s infotainment system. The only way to permanently disable this function is to alter the software inside the ECU. This way you can have it turned off completely.
Good news, if you have customers at your shop who wants to turn this off in their cars, we at chiptuners have a working solution for this.
