Yesterday I got my C-Max again after the LPG conversion. Now it falls on me that the residual kilometer indicator in the on-board computer normally counts down although I drive with gas and now the yellow lamp has approached at 80km although the petrol indicator shows 3/4 full. What is going on? Does the on-board computer only calculate the restliters based on the distance and does not notice that is taken from the petrol tank nix?
