My fuel gauge on my S3 has started doing the little up and down dancing thing at the bottom instead of showing me how much I have left in the tank. Is it likely to be the float, gauge or the electrics along the way somewhere? Am dreading trying to repair it whatever it is tho....... :o(
Many thanks, Tim
My car does the same thing, and it is due to corrosion and crap on the sender unit on the tank. s'got a coil in it and the float moves a contact along that coil. I suppose it could be the guage too, but i'd check the sender first.
Voltage regulator... well that my first guess anyway. Stick a multimeter on a voltage regulator and it should kick out an average of 10.4 volts if my memory serves me correctly.... However trying to read an average on a waving needle is another matter.

Remove the two wires from the fuel sender. Earth them one by one. 1 of the wires will light up the low fuel level warning light. The other SHOULD send the fuel guage to full.
If it does, the fuel sender is faulty - they are only about thirteen quid - replace it.
If it doen't, then EITHER the fuel guage or wiring is faulty.
To find out which, take the guage console out but leave all wires connected. Find the + supply o the fuel guage and earth the other terminal - if the guage (with ignition on of course) reads full, then its wiring. If the guage does not move, its the guage that is faulty..
many thanks everyone.
