GeorgeBoxster Posted February 29, 2020 Report Share Posted February 29, 2020 987.2 Low fuel warning light permanently on and at least third full...Any pointers guy's ? Link to comment Share on other sites More sharing options...
antjrice Posted February 29, 2020 Report Share Posted February 29, 2020 Does it turn off if you refill the tank entirely? My C4S does this by design as it has a split tank and the sensor is only in one side. Sounds daft but makes sense when you think about it. No idea if the 987.2 has this though.

sa utah Posted February 29, 2020 Report Share Posted February 29, 2020 One of my previous cars would show no fuel sometimes even though it had had some put into it. I’d do a battery disconnect for a while. Do t forget you’ll maybe need to reset the windows etc as usual. id use it as a good excuse to fully charge the battery too.

I have not filled it fully so maybe that might work Link to comment Share on other sites More sharing options...

The battery is on a trickle charger and fully charged Link to comment Share on other sites More sharing options...
sa utah Posted March 1, 2020 Report Share Posted March 1, 2020 Well like I said I’d certainly be trying a battery disconnect for a good hour Link to comment Share on other sites More sharing options...
bally4563 Posted March 3, 2020 Report Share Posted March 3, 2020 Any outcome to this?, only seem to recall reading something that you have to fill it up if it's been left empty ish for some time, and once full requires recalibrating with PIWIS ?
