1997 BMW 318iS manual coupe - fuel warning light stays on
The fuel gauge warning light remains on in my '97 318iS manual coupe after I filled up with fuel, it is possible that I over filled it. When I've accidentally done this in the past the low fuel warning light has come on but usually turns off after about 50km of driving. On this occasion it has done over 350km and not turned off. The car has been stopped and started many times during this 350km period.

i'd change the engine temperature sender unit , or just disconnect it for a while and see if the gauge symptoms disappear , if they do then change the temp sender unit,if the symptoms remain i'd say get the OBD codes read as may have a faulty dash component
Usually attached to the Sending Unit of fuel pump(in the tank). The module will get its signal from the float arm. Look for components that touch the fuel pump float arm, then trace the wires. Keep us informed =D
My experience is with a 98 and a 99 cavalier but I don't think the changes from 97-98 included the cluster, so here's my experience. There is no designated warning light for the fuel gauge. When the gauge gets to almost empty(just a millimeter or so above empty) the red "check gauges" light will illuminate. I don't know whether you have had the tank this empty or not, but periodic checking of the cluster should make you notice if the level is this low. Hope this helps, it's all I can say with the info posted.
