Adjusting the fuel gauge/sensor: Notes

There are two different ways of adjusting the sensor/gauge, depending on the fault symptoms: whether the reading error is "equally large" from full tank to empty tank or whether the reading error occurs only at a certain level. Adjustment of the fuel level sensor offset or, alternatively, the fuel gauge reading, is possible.
