Small Petrol Tank In My Fg?

[PHANTMXR6]

I've had the same issue with mine since new.

What I did was fueled up the car based on how much has been used on the dash readout.

That one is almost spot on.

My gauge and distance till empty readings are now a lot closer.

What I did was run it down to 60litres used regardless of what the distance till empty readout was and the fuel guage for 3 tankfulls.

It's now pretty much sorted.

so what you ran it past empty and 0km range? I wasn't game to try that just in case the problem was the tank wasn't filling properly.

[PHANTMXR6]

Yeah I did panic a bit too for the first couple of tankfulls, but then worked out the fuel usage counter was reading accurately so I let it get down lower before filling it.

Here's an example.

Distance Til Empty (DTE) counter reads 0kms.

Average Comsumption reads, for arguments sake, 17L/100kms.

Fuel Consumed counter reads 51.3L.

I fill up the tank and it only takes 52L.

Not really rocket science but there is no way the tank is empty or anywhere near it.

The next time.

DTE reads 0kms.

Average Consumption reads 17.2L/100kms.

Fuel consumed counter reads 62.4L. ( I've done an extra 70-80kms since the DTE has read 0kms.)

I fill up the tank and it takes 63L.

I do this a few more times and the DTE gets a lot closer to what it should be.

I've found the Fuel Consumed counter to be so accurate I don't even bother with it. I just go off fuel consumed and fill my car if it gets just over 60L.

Thanks - I'll give it a try. cheers, David

I took Phantmxr6's advice and ran the tank down past empty using the litres used readout. managed to get to 62 litres before I chickened out and refilled it. (it was showing empty and 0km range at 45 litres used)

Anyway the dealer had the car again week - fitted a new fuel sensor. Seems to have helped the calibration.

Have just filled up for the first time since the new sensor was fitted - I'd say its fixed the problem mostly - I'll see how the next few tankfulls work out.

I've had my G6E Turbo for 3 weeks now, and it's pretty accurate.

Filled up last night and it said I had burnt 61 Liters, I filled up 60.5 liters.

I doubt the dealer had just bent the arm as that would probably be a tank out job, correct me if I'm wrong, you may be able to do it with the tank in the car. All cars from new generally have a very high fuel usage reading, so the average fuel consumption is through the roof, maybe it takes a couple of tanks to sort it out and let the computer know that there is actually heaps more kms to be had out of the tank and not 0kms. Anywho glad you got it sorted!

[PHANTMXR6]

Yep. Tank out isn't necessary.

All that has to be removed is the bottom section of the rear seat.

Once removed, on the passenger side you will find a big rubber plug/grommet, about 6-8 inches in diameter.

Under that will be the intank fuel pump and sender unit.

Pretty straight forward for a pump or sender replacement.
