Allroad Quattro V8-4.2L (BAS) (2004)
-
-G-, -G169-, and -G237- are switched in a row. For that reason all 3 are tested together.
-
To test a single Sender, it must be removed
-
To test the resistance value of "Full tank" and/or Empty tank" swing the float to either the upper end position and/or the lower end position
-
If a malfunction is suspected, check the resistance value of the installed Sender 3 (dependent on the level) by disconnecting the connector at
Sender 2 and measuring resistance at that connector.
With sender for fuel gauge or fuel level sensor removed, the following values will result due to the longer reach of the float arm:
Vehicles with build date up to approx. 02/99
NOTE: On vehicles with a build date up to approx. 02/99, if any of the Senders for fuel gauge are found defective, all 3 Senders must be replaced with
those for vehicles with later build dates. Connect the multimeter for voltage measurement to contacts 2 and 3.
Vehicles with build date as of approx 02/99
NOTE: As of the approx build date of 02/99, the resistance value range of Senders II and III were changed. The total resistance value however stayed
the same.
