Hi can anyone please help me
my fuel gauge is rapidly decreasing both the digital fuel gauge and the needle one.
in 5 minutes it went from half a tank to almost empty the digital went from 119 to 43.
I have a video here please check it out to see for yourself and maybe you can help me diagnose this issue
many thanks

 

Assuming you don't have a major fuel leak, i would suspect a bad sending unit.

 

Thanks for the reply il be sure to look into this
i did have a google search and it did not come up with anything. So this is helpful info thanks

 

+1 bad sending unit ,, or the cluster is wonky since IIRC there is some CAN bus dependencies in there...

 

If it’s the cluster I hope it isn’t a hard job to replace I’ve never done anything like that to this car. I reckon I can figure out how to do the sending unit but cluster I’d be a bit worried damaging anything.
You think it’s an easy job if it’s the cluster?

 

If its the cluster the car will require a trip to get access to a PWIS to re-code the new cluster to the car.
None of the diy's indicate getting the cluster out requires super human skills. I would still bet on the sensor
because the Mileage and gage are behaving the same so it means a common point of failure,,
the sensor is EASY..

 

That’s a good point thanks. Il give it a go but at the moment I’m living with it as some days it’s fine the next day or plays up so it’s intermittent. I am putting money aside for it as I want to do a few things at the same time like the MAF sensor and give it a service.

Thanks for all all the help everyone
