Fuel gauge sendersG: Check
Fuel gauge senders -G-: Check
Consult the equivalence table for tools and equipment according to applicability among Seat / VW / Audi / Skoda → Chapter.
Special tools and workshop equipment required
   
t  Manual multimeter -V.A.G 1526C-, see equivalent → Anchor
  W00-10311
t  Auxiliary measuring tool -V.A.G 1594C-, see equivalent → Anchor
Operation process
–  Remove rear right seat → Bodywork - Interior fitting work; Rep. gr.72.

–  Connect the multimeter and measure the resistance between contacts -2- and -3-.
Fuel gauge sender -G- installed:
l  Sender on the lower limit: approx. 270°Ω
l  Sender on the upper limit: approx. 70°Ω.
  Note
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  If the value 0 Ω is achieved, a short circuit exists; the value ∞ Ω indicates an open circuit in the wire.
t  The following values are obtained with the fuel gauge sender -G- removed, due to the greater travel of the float arm:
Fuel gauge sender -G- removed:
l  Sender on the lower limit: approx. 290°Ω.
l  Sender on the upper limit: approx. 60°Ω.
–  Connect the multimeter and measure the resistance between contacts -3- and -4-.
Fuel gauge sender -G- installed or removed:
l  Sender in any position: approx. 340 Ω.
Installation is carried out in the reverse order; note the following:
