To do a drain test,disconnect the earth terminal of the battery(make sure you've got his radio code if needed!),and put the multimeter between the earth lead and the battery negative terminal(ignition off).Check the amp reading,anything below 0.3amps is absolutley fine.If the reading is OK,then suspect the battery.Test the battery under load if needs be.

If it's above 0.3amps,then start removing fuses and rechecking amp drain.Obviously if the drain drops when a certain fuse is pulled then the fault is on that circuit.If the fuses don't give any joy,then start disconnecting the alternator etc.

I must admit,I'm not sure about the fuel gauge readout,but it could just be a damaged unit or a backlight bulb gone.

Sorry if this is teaching you to suck eggs!!!.You probably now a darn sight more about this than me!.

I should have been a carpenter(like my Dad),but I decided to become a motor tech instead.......oh how I regret my decision!Give me wood to work with and I'm a happy bunny,give me a car with an intermittant fault and an un-understanding customer and it's a different story......

Good luck,and let us know how you get on.

I'd rather push my Alfa than drive a BMW....
