Hello everyone, I have a problem with my Gallardo Spyder 2008. the meter indicates a full tank of fuel all the time. anyone have any wiring diagram that can help me? thank you very much everybody. I hope you can help me :confused:

"All" the time? The reason I'm asking is that it's pretty normal for the analog gauge to read full even when you're close to half a tank (mine just lifts off the full mark when I have about 60% fuel). But when you're closer to empty (trip computer reads 100 miles for example) you should definitely see movement.

thanks for the info but the meter does not move even a little is why I suspect that the car has a problem with some electrical wiring. the really do not want to drive until fuel runs out, because I can damage the pump. thanks

Are you saying the trip computer doesn't tell you the number of miles left on the fuel you have? That would definitely indicate some kind of sensor problem.

if you problem is on the instrument panel you can try disconecting your fuel gauge sensor on the fuel tank, if you disconect this and still having " full tank" your problem is with the wiring... al rato te veo para hacer el paro!!! :p

Yeah, this isn't a beater you slowly let fall to pieces. Always keep it 100% so you can enjoy it to the fullest.

Here is how it work on my car, which is normal
the gauge will read up when tank is 2/3, then it'll decline. the onboard computer does the same too. it says 275mi+ left for first 2/3 of the tank and then start counting down the miles left.

If yours is 100% all the time for more than 1/2 of the tank, something is wrong. If your fuel range reads 275 mi + all the time for more than 1/2 of the tank, I suspect it's a hardware issue rather than instrumentation issue. Most likely a sensor failure. Maybe start with fuses?

do you know wich module controls the fuel gauge? because we make test on the fuel gauge sensor in the fuel tank and its ok and it looks like if the instrument panel its ok.
i suspect fromo the module wich control the fuel gauge but i dont know wich one is...

i dont know. however, all the control modules and fuses are either under the passenger footwell or under the rear interior shelf right behind the seats.

you can look at shop manual or ricambi's parts diagram to see if you can figure out the wiring.

maybe contact a few lambo specialists?

tests were performed on the floats of fuel and are in good condition and the instrument panel, I have the suspicion that the problem is the control module, but do not know which of all is, you know the name of the module? is programmable? thanks!

Almanzar-

Did you ever get your fuel gauge problem fixed? If so, can you give us an update??
