Hi, has anyone had any issues with the fuel gauge not working properly, It's showing the wrong reading.

Any ideas to what it might be?

Thanks, I will check it. The fuel gauge is working but not showing the correct level.

Mine is not always accurate either. I've seen it down to a quarter tank, then next time I start the car it is up to half. Maybe it is just the way it is.

IIRC older multiplexed PSA fuel gauge info works differently from other vehicle manufacturers.

Ignition switched on - BSI looks at the tank sender unit & uses that info to display the fuel level on the gauge.

Once engine is started the BSI now ignores the tank sender unit reading & calculates the required usage information from the engine ecu which monitors the fuel usage & calculates that in to the fuel level gauge to display the reading.

I've no idea if Peugeot are still using this same design strategy on newer products.
