I'm not what bmws you are referring to, but the ones on this planet have no such system.
How does the DME control voltage reguLation on an alternator????

There is no way any car can tell if you changed a battery. Period.
Perhaps confirming the new batterY is FULLY CHARGED before installing would prevent from frying your alternator.
The alternator doesn't CHARGE the battery voltage... It MAINTAINS it. Big difference...

If anyone can provide me BMW documentation or a procedure for registering a battery I'll shut my mouth. Lol
