Adjusting the Fuel gauge/sensor
|
There are 2 alternatives for adjusting the fuel gauge display depending on the fault symptom. If the error is “the same” from full tank to empty tank or if the error occurs only at a certain level.
Alternative 1. Gauge reading error across the whole scale.
Adjusting the tank offset involves adjusting the fuel level sensor input to the MIU. The tank offset can be adjusted -5 to +3 litres. This command affects the Fuel Level reading and the reading on the fuel gauge.
After adjusting, turn the ignition off/on. Use the “Fuel level” reading to check the adjustment.
