–  Connect the hand-held multimeter -VAG 1526C- to measure resistance between contacts -2- and -3-.
Fuel gauge sender -G- installed:
l  Sender on the lower limit: about 53.5 … 59 Ω.
l  Sender on the upper limit: about 300 … 310 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 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.
t  The following values are obtained with the fuel gauge sender removed on account of the greater deflection of the float arm:
