The battery goes dead after a few days of not driving the car. I do not have any interior lights left on or any thing other than a stock radio. Anybody have any suggestions as to where the drian is coming from? Someone mentioned at one time about the trunk light possibly staying on all the time?????

Im not sure if the trunk gets offset or the mechanism itself fails, but its a very common problem. Climb into your trunk and have someone close it and if the light stays on, thats your problem. -
if it is not a drain item it could be due to the age/wear of the battery (assuming it is more than a few years old).
I think there is always a very small drain from car alarm etc.
Mine acted like yours last year and replacing the 5 year old battery with a new Interstate batt was the fix in my case.Petro

I have the same problem. Is there a general procedure to test where the drain is coming from? I tried putting a voltmeter on the fuses when the ignition was off and about half were hot and half were off...

Unhook the battery cable, and hook up a voltmeter to measure the amperage draw when the car is off and @ rest. Then start unplugging fuses one circuit at a time to pinpoint what circuit has draw. Once you identify the circuit, then start eliminating componets on that circuit. Some things will always draw a little power, like the computer, clock, etc.What??? an E30 M3 for sale??? I'll be right there!!!Comment
