Gas Gauge STILL has problems

switch-off. Then start filling the tank with
fuel again until the fuel pump nozzle switches
off.”

Worked for a while and did it again several more times in a row. Took it in again for service. This time when I stopped for gas just before reaching the dealer and the gauge went to full.

Service Advisor said they could not fix anything that was not broken as no scan codes showed up. The next fill up the gauge still did not read full.



I will call smart again for service. But now I need real answers to final solve this problem. Does anybody have a concrete solution to the gas gauge problem? I am tired of the long drive to the service center. I guess I could try another dealership's service tech.

i had the same problem. the flash to the ecu was done and it wnet to full one time. then went back showing 3/4 full after fill up again. so went back and through smart tech at heaquarters they said to reflash, unplug power to the instrument panel which takes 2 minutes, and plug back in. smart dealer did this in that sequence and it has worked fine now for over a month. if your smart dealer needs to talk to the guy who did have them call smart dealer in columbus ohio and ask for the lead smart tech.

Is there a reason why I would want to fix the carbon canister in the vent if it does get soaked? What if I just ignored it? Does that canister even exist in Euro models?

Why would it read full last week, but not this week?

Duckhunter - is it safe to top off like that?

On a positive note, I averaged 37.3 mpg on my first fill-up

So this is weird. It's been about 50 miles since I filled up the gas tank, and when I turned the car on, the gauge read 8/8

I am having the same issue - I fill up and it only shows 7/8 of a tank... I called the dealer and they have seen a few do this - they told me to fill it up at a close gas station to the dealer and bring it in so they can calibrate the indicator.
Not sure how they do that, but in a few days I will share what I learn.
