Adaptation of fuel gauge sender resistance range

This function is used to adjust the fuel gauge sender resistance range if the fuel gauge display in the instrument cluster does not match the actual amount of fuel in the tank.

NOTE:

"128" is the adaptation value for the standard resistance range for the fuel gauge sender as set by the factory.
The resistance value for the fuel gauge sender resistance range can be adjusted by +8 Ohm to give an adaptation value between 120 and 136..
If the value "128" was changed due to a customer complaint, the changed value must be transferred when replacing instrument cluster.
