Fuel Gauge reading empty - Vauxhall Astra H 1.6 2008 5 Door

Post by willjicar » Mon Feb 10, 2020 3:50 pm

Hello everyone,

The fuel gauge of my Vauxhall Astra H 1.6 is reading empty even though it is half full.

Yesterday I had to take my battery out and charge it (Bad connections on stereo I suspect, I usually take my stereo out when I turn the car off, but the past few days i've left it in and now the battery is dead, not the first time it's happened).

When I put the battery back, the car works but I noticed the fuel gauge all of a sudden is stuck on 0 and the Low Fuel light is flashing. I'm not sure whether this is a mechanical problem with the fuel tank or an electrical one with the signal not being transmitted.

I've not done any diagnostics on it yet and i'm hoping it's a cheap fix lol

This forum is for the BK models
You’d be better off posting in an AH forum
I’d hazard a guess it’s the sender unit or a fault with wiring somewhere

I’d suggest an auto electrician to look at the wiring from the fuel sender to the ecu unit
