Fuel Consumption gauge problem

[General984]

So I have a problem with this useless gauge,but I still want to fix it.
When I turn the car on for first time it goes over 30/l,where it is supposted to be in neutal.
As soon as I move that car for a few meter it goes back on 0 and stays there forever...
Did anyone expirienced such problem?

check the fuel sender in tank http://bmwe32.masscom.net/johan/fuel...el_sender.html

I checked it not a while ago when my fuel gauge wasn't working,after I replaced tachometer it works just fine...
But consumption gauge still doesnt work.

any other faults like these? http://www.bmwe34.net/E34main/Mainte...eed_sensor.htm

[General984]

Nope,all gauges work perfectly fine.

blown resistor in cluster? http://bimmerboard.com/forums/posts/467642/

[General984]

Checked,resistor is fine.

Anyone else has idea on this? Has General Module anything to do with consumption gauge?

My wiring diagrams are only for US-spec models, which exclude the 525TDS. The schematics also don't go into detail about transistorized circuits. That said, the GM does not appear to be involved with the consumption gauge. Only the gauge cluster, the engine computer, and possibly the OBC are involved.

My cluster and OBC are fully functional.
Maybe it could be the wire between computer and cluster.
