Does your fuel gauge Lie?

[Ian318IS]

Just another quicky is there anyway to test the fuel warning light (without actually running that low on gas?) only ask becasue mine has gone right deep into the red and it has never come on so ive assumed its knackered?

Fuel light?! I didnt know there was one and i have run mine all the way through the red.

Mine lies too! I didnt know they had a fuel light also! Where is it?

i think my fuel light comes on a little early, but the guage dont lie, tho its a little pessemistic (sp!)

says what it wants to say really! sometimes i'll be driving it and look down and see its dropped by loads. then i'll stop the car and get out and whatever, then go back to the car, start it, drive off, and it says something else!!!

Similar problem, but usually the somethin else is a little bit more on the plus side so thats cool!

An easy fix u say?

My understanding was that the light comes on once you get to your reserve which should last 40km/24miles? Seems about right, my light works and once it goes on I can drive to work in the city about 35 kms away without having to refuel. The first thing I would check if you don't think its working would be the globe (need to remove instrument cluster for this). If the globe is fine and the instrument cluster is out you then might want to have a look at the actual circuit board and check its undamaged. Maybe check the fuel sender unit and replace? Just some ideas.. hope they help

Is there a guide to changing that fuel sender on here??

Anyone fancy putting up a description??

If it's only a five minute job i might have a crack at it one day!!

My E34's fuel gauge is quite honest, I believe it enjoys mocking me with its heavy drinking problem, (running stupidly rich) but the temp gauge is away with the fairies 50% of the time
