SEAT Workshop Service and Repair Manuals

Checking fuel gauge sender -G- Consult the equivalence table for tools and equipment according to applicability between Seat / VW / Audi / Skoda → Chapter Special tools and workshop equipment required

t  Manual multimeter -VAG 1526C-, see equivalent → Anchor

t  Auxiliary cable kit -VAG 1594C-, see equivalent → Anchor Operation process –  Remove luggage compartment floor lining. –  If necessary, fold forward right backrest of rear seat bench.

–  Loosen the bolts -arrows- and remove the fuel delivery unit.

–  Extract the connector -arrow- from the fuel delivery unit.

–  Connect hand-held multimeter -VAG 1526C- for resistance measurement between contacts -2- and -3- to measure voltage.

Sender fitted	Sender on the lower limit	Sender on the upper limit
Fuel gauge senders -G-	300 … 310 Ω	53.5 … 59 Ω

Note t  If the value 0 Ω is achieved, a short circuit exists; the value ∞ Ω indicates an open circuit in the wire. t  To check the resistance (values corresponding to „tank full“ or „tank empty“), the fuel supply unit must be removed → Chapter and the sender float moved all the way to its top or bottom positions. t  With the fuel level indicator sender -G- 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-	271 … 296 Ω	55 … 69 Ω

Installation is carried out in reverse order.
