This is a sore subject with me... the BMW E36 (3 series) is notorous for EVAP system faults. It's almost NEVER the gas cap or has anything to do with the cap. It's a leak somewhere in the system that causes pressure differential that the computer doesn't like... This drove us nuts until we sold the car.
