These will help.

Thanks.

If all voltages checked ok,then most probably its faulty instrument cluster board on which gauges are connected.Yes if cluster circuit board looks ok,then also it can be faulty.Somewhere there is minute short or burn on board then such prolem arises.
Also check the fuse box.One under hood and other under dash.Inspect each and every fuse and see if all are fine or not.

The sending unit in gas tank is broken - hence the wrong readings of how much gas is in the tank. Replace unit.

possible blowen fuse or a bad sending unit inside fuel tank also check the connections at the tank

the problem is caused by a defective gas gauge sending unit, this part is located inside the gas tank, you must remove the gas tank to replace it.

was the gas tank empty or full some times the gauges won't work untill the tank is full or the wire for the gauge was not put on properly

Those vehicles have to sending units. Your fuel signal is buferred ( calculate) so it takes both signals to make your gauge accurate. sounds like one them is out of range causing your gauge to read icorrect. You do need to take to your nearest BMW shop, so it can be properly diagnose.
