fuel gauge

Hello people. I have a problem with my fuel gauge. It reads like a half and a little bit more, even when on empty. It never moves, only when I turn off the car. Is there anything to do with it? thanx a lot

Welcome to the club, my #1 E30 has the notorious erratic fuel guage, seems the newly purchased #2 is fully operational but only time will tell. It's a very common problem and an easy fix with a new sending unit installed under the back seat

i tried replacing the sender only to find it was the guage itself. it sort of works now, shows F when i fill up but seems to quickly drop after the half-way mark.

so I have tried twice now in the past couple of months to lift up the back seat..as you can tell I am in a huge hurry to fix this.....is there some kind of trick? do I just need to work out my arms for the next month and then try again?

maybe the previous owner used gorilla glue on it!!!

Use a bit of pressure from your knee while pulling up on the seat at the same time, should pop right up. On the passenger side you will see a black access cover. Take that off and you will see the lines coming off the pump assembly. There are four small nuts visable, 6mm I think, remove those and lift the sending unit straight up.

O_O Theres another fuel gauges under the seat? I don't understand the new sending unit installed under the seat ideal.
Mine works fine but gets a little crazy after it passes the half way mark.

Also...it could be that the screws on the gauge itself are loose...look at the dash...look at the gauge...and you'll see the screws I mean...another common problem...
