Hi, my car listed above shows fuel type wrong. It shows all the time 2 different types same time, Unleaded and Diesel. There should be Unleaded (Premium ?) Fuel only, but absolutely no Diesel. ;) Is there any way to reset this and show a correct information?

Good evening,

That information comes from the body control module for the display. It is part of the programming internally.

The BCM will have to be reprogrammed to get it to correctly display the fuel type.
