Battery Drain 2002 530i manual transmission with 250K mileage.

What is your question?

Car, 2002 530i manual transmission with 250K mileag, was totally dead and was jumped. Battery, alternator and generator checked at BMW dealership and by AAA. Car is experiencing a battery drain where sometimes you turn the key in ignition and there is nothing- no sound or clicking. Have not been able to determine where the drain is coming from- glove box light, trunk light, fan module etc. This happens immediately after driving the car. I can wait a couple of minutes and then the car will start. I notice upon letting the car sit and when getting back in the car, the inside courtesy lights will go on- (that is the sign the car will start) Before I take it back and probably pay some big bucks, are there any suggestions for where to check and how to check

How long has your 2002 BMW 530i had this problem?
