Adjusting the fuel gauge/sensor
|
There are two possibilities of adjusting the fuel gauge reading, depending on whether the reading error is of the same magnitude from full to empty tank or whether it occurs only at a certain fuel level.
Alternative 1. Gauge reading error across the whole scale.
Adjustment of Tank Offset means adjusting the fuel level sensor's input to the main instrument unit. Tank Offset can be adjusted from -5 t +3 litres. This command affects the Fuel Level read value and the fuel gauge indication.
After adjustment, switch the ignition off and on again as a check. Use the “Fuel level” read value to check the adjustment made.
