Cayenne S Fuel Gage Issue

[spirosqatar]

Hello to all members. I'm new in the forum.

Recently faced a problem with my Cayenne S & need an advice. Usually im filling my pertol tank every 4-5 days (depends on the mileage driven). Last time the fuel reading was almost to enter the last line (empty) but still no indication for refilling on the dash board. I fill up 52litters & the fuel reading hit 3/4 of the tank when the pump nozzle has switched off. Usaully im filling 65 to 70 litters. After driving the car to my destination & return back home the reading shows no almost full.

The problem should be from the pumps/fuel sensor or both?

Anyone faced a similar issue?

Thanks

Spiros

Your fuel tank volume should be 100 litres and the reserve light come on at apporx 90 km's to empty which is to be taken with a grain of salt. Are you filling at the same pump each time? What if you fill the tank slowly?
