Strange single beep from rear of car

My 2003 540i is beeping, and I can't figure out why. This is a single beep, so it's not the 3 beep issue I've seen referenced elsewhere in the forum. The beep happens whether the ignition is on or not. When I start the car, it happens every 30 seconds. With the ignition off, it happens less frequently; I'd guess every 3-5 minutes. I started the car, and there are no warning indicators.

It seems to be coming from the driver's side rear of the car, although it's difficult to pinpoint the exact source of the sound. You *almost* can't hear it while the engine is running and the windows are up; it's much louder outside the car.

Any ideas?

Possible malfunction of the vapor purge system, housed behind the LR fender liner.

Thanks for the tip, Ed. I just ran my fuel tank lower than it's ever been, so you may be on to something there. It's now beeping every 30 seconds with the ignition off. Guess I'll have to take it to my indy for a diagnosis.

Well, this is embarrassing, but to close the loop: the car is NOT beeping. My garage door opener's backup battery is dead, and that's what's beeping. Oops!
