SEAT Workshop Service and Repair Manuals

Checking fuel gauge sender -G- Special tools and workshop equipment required

t  Hand-held multimeter -VAG 1526B-

t  Auxiliary cable kit -VAG 1594C- Checking sequence –  Remove rear right seat → general body repairs, interior; Rep. gr.72. –  Detach carpet under seats and fold it back.

–  Release retainers -arrows- at cover for sealing flange.

–  Release carefully electrical connection -arrow- on sealing flange and take off.

–  Connect the manual multimeter -VAG 1526B- and measure the resistance between contacts-2- and -3-.

Sender fitted	Sender on the lower limit	Sender on the upper limit
Fuel gauge senders -G-	Approx. 270 Ω	Approx. 70 Ω

Note t  The measurement value 0 indicates a short circuit; the value ∞ Ω indicates an open circuit. t  To test the maximum and minimum resistance values for „tank full“ and „tank empty“, remove the fuel delivery unit → Chapter and move the sender float all the way to its top or bottom position. When the fuel gauge sender -G-is removed, and due to the large floater range of movement, the following values are obtained:

Sender removed	Sender on the lower limit	Sender on the upper limit
Fuel gauge senders -G-	Approx. 290 Ω	Approx. 54 Ω

Continue the installation in the reverse order of removal sequence, observing the following: –  Fit rear seat → bodywork - interior fitting work; Rep. gr.72.
