My battery keeps draining... My battery is either dying, or I have a parasitic battery drain. Does anyone know how many (milli)amps an E46 330 should draw when it's asleep, please.
My car suffers from battery drain which warns me by the klimatronic Panel going completely offline this will give me one day of driving before I have to fit "The OTHER" battery, I have come to the conclusion (with the advice and help from our Forum members) that it the FSR is defective, BUT!!! I am to lazy to Change it yet
I cannot measure the draw at the Moment cause my Voltmeter/ammeter is at the Workshop, but logically if your battery is draining then it is not a normal power usage while car is in sleeping mode, then you have a light that is permenant on ie. glovebox, boot or something like a charger is plugged in to a permenant supply etc.
i also have the same problem, how is it that you test for a drain? if i remember you disconnect the earth from the battery, clamp the multimeter to both the earth strap and the battery. then find away off holding in the boot and door switch closed so you can lock the car and see if theres more amp draw then there should be right? then pull each fuse one at a time to see what is draing it. is this correct ???? for about six months ive been disconnecting my earth strap eveytime i leave the car this sucks belive me but it better than a flat battery
