Fuel Gauge Issues….(A genuine club post!!!!!!)

[9designs]

Do you have a DSC module, as it does fuel gauge as well, as did the Ford module.
I found if or when the car’s battery is getting down or knackered the module isn’t always remember or recognised, hence the drop and reconnect symptoms you see.

No DSC module fitted but are you saying it can happen with the ford module too, and as such the battery could be starting to go south.

Original battery still on the car but still seems OK as I have had no other issues.

I thought that the fuel gauge was a symbol or guide without a direct connection to a float in the tank or any mechanical measurement.
just a reassuring retro feature.
my gauge needle reads low if the car thinks that I won’t get far on what’s left.
So if the car thinks I’ll go 20 miles only the reading is just above empty.
then when the car realises I can go over 100 miles it reads half full.
so it judges by driving style?
controlled by software?

Not exactly sure how it works but have checked the manual and there is a dual fuel pump/sender unit in the tank….

but you have to remove the whole tank to get to it!!!
