The fuel warning light works from a different sender to the guage itself. There will normaly be a sensor near the guage sender that will be submerged in fuel, it sends a tiny electrical current through the fuel, when the level drops to below this sensor, no current is recived and the fuel light comes on.

No current would explain why the light is on even though there is fuel in the tank.

Only thing i can suggest is check the fuses, check any earthing points on the sender or around the tank, trace the wiring back to the UCH and look for breaks or loose connections. Failing that you might be looking at the UCH being faulty as everything on Lag II's goes through that.
Currently in Mikey's garage:
1996 Mazda MX-3 V6, a 2002 1.2 8v Fiat Punto active (the Wife's!) and a 1998 Suzuki GN 125. Used to own a 2002 Laguna II Dynamique 1.8 16V (Now Sold yey!)
