I myself have been trying to figure out how far the key fob has to be from the vehicle before it shuts itself down. For example, upon exiting, the iDrive screen will display a message about the key not being in the cabin, suggests there may be a malfunction, etc... but will it actually shut off the engine if the fob strays far enough with the engine running and specifically with the doors unlocked? So far I've only walked 3-4 houses away and that wasn't enough...
