Vauxhall Astra H (2004 - 2009) - Fuel gauge reading incorrect | Technical matters | Back Room Forum

Fuel gauge reading incorrect - mjmherts

Hi everyone
This is my second Astra H and it is displaying the exact same fault as my previous model.The gauge will read 1/4 of a tank but will be run out of fuel.My previous model was petrol and I learnt to keep it topped up but cant believe my new one (diesel) has the same fault !
I have read the road test report on this site and it states in the 'What to wach out for' section that a faulty reading gauge could indicate a fault with the (REC) rear electrical center ?
Please can anyone shed any light on this issue
Many thanks

Just learn to live with it ~ there are a lot worse things you could have. You'll soon work out how far you can drive before you need to fill up. No fuel gauges are absolutely accurate.

The last time I dealt with a mis-reading fuel gauge the cause was a fuel return pipe in the tank becomming unclipped and interfering with the float on the sender.

I can't remember absolutely relying on the fuel gauge in any car I've ever owned. Most recent ones seem to stay on full for a disproportionately long time then zoom down to quarter full and take a longish time to do the last quarter tank. Never regarded it as a fault, just something to live with.

But as AE says, is it still showing 1/4 tank when it splutters to a halt? Does it have a low fuel warning light, if so does that work?

But you need a fairly accurate gauge to play fuel light bingo, otherwise it takes all the fun out of it.

Yes as in run out of fuel !
The light did not come on because the gauge was not reading that low to trigger it

Hello,

I know it's been a long time since you started this topic, but I was curious if you managed to find out was causing the problem. I have the exact same issue, the needle of the gauge indicates that I have a quarter of tank when in reality I only have 5 or 6 litres of diesel. Thanks!

On most vehicles,the low fuel warning light is wired to the gauge not the tank!

It's not just a problem with the warning light, but the needle just doesnt go any lower than this: i.imgur.com/GVHJDYD.jpg Maybe just a bit lower when I'm practically out of fuel.

When I took the picture the fuel in the tank was 4 litres (as shown in the secret menus) and that is correct according to my own calculations about the remaining amount of fuel left. I recently bought the car and I just discovered this problem.

Thank you all for your help.

Hello again,

Unfortunately, I think that I may have been blessed with the Rear Electrical Center fail: central locking has stopped working suddenly. This, along with the incorrect reading from the fuel gauge seem to be exactly the symptoms of a failed REC. Can anyone please tell me how much would it cost to replace it?

Thanks!
