I think that's the battery cutoff which is automatically activated when you're in an accident.

Sorry, I don't know specifically, but I wonder whether you cars has a trailer hitch? Mine does, but the electrical plug is not wired to provide charging or constant power to my caravan. Dealer told me they could install extra wires to provide this, but it puts a heavy drain on the car battery so I should have an on-off switch installed as well so I could select when I would want to provide power to the caravan, lest I might not be able to start up the car again. Could that be it?

I want to agree with 'gcvt'. Your car has a BST or Battery Safety Terminal that shuts off the engine in a bad collision.
However, I believe Main Battery Switch is actually a cable and switch installed at the factory for cars shipped overseas. I believe the cable and switch allows the car battery to be disconnected for long periods and then turned back on temporarily for moving the car during the shipping process. Its probably removed at final destination. BMWs have had this 'option' for years.

Found this below on another website - here is the link - scroll down a few frames from the top... there is a pic of it as well. I realize its for a 3 Series but its the same option number and name as on my build sheet.

Well here it is, my 1st mod of 2010. After 3 years of looking, I finally managed to source an original killswitch that BMW uses.
It's option:
S818A MAIN BATTERY SWITCH |Battery master switch 900A APPR. VEH.IMMOBILIZAT. ACC. TO AZT/TUEV Electronic immobilizer.
Supposedly it's used by BMW when they ship and store cars, but it taken out of the car when delivered to the customer. People will have the option on their list, but will not find it fitted to the car.
As I do many modding that needs for the battery to be disconnected, this will make my life much easier
Of course you can buy a killswitch in every automotive store, but people who know me (by now), know that's not the point.
