9023 Fuel level display

Problem
• If the power supply is interrupted by a discharged or
disconnected battery with the tank containing less than
19 l, the calculated value for the range on remaining
fuel in the instrument cluster will be incorrect or
deleted.
• If the tank contains less than 10 l, it is possible that the
fuel level warning light is no longer activated.
• If the power supply is restored with the fuel level at
less than 19 l, it is possible that the fuel level display
may subsequently display too much.
This may lead to the vehicle breaking down.
