Fuel gauge adaptation

NOTE:

The adaptation only affects Reserve and has no affect on the "full" mark.
The pointer of the fuel gauge must be positioned on the right red line (reserve) of the fuel gauge when the display shows OK.
When the VAG 1551 Scan Tool is connected and the fuel gauge adaptation was selected, the "low fuel signal" is automatically deactivated.
If only the VW1301 instrument/gauge tester is connected, the "low fuel signal" must be activated by switching the ignition off for 2 minutes.

For the adaptation of the fuel gauge, the fuel sender -arrow- located under the luggage compartment cover must be disconnected.
