Yep, no such thing as a bargain car!

I’ll have to find it. It came from an M3 technical document designed for SAs and technicians.
Also had a discussion w/ the M-certified technician who fixed my E90 about this very subject.

Hmm, well the info I found is a little ambiguous, although what I've found so far points to electrical switching of the alternator (especially pic 2), also I found nothing about a clutch for it. Nor have I ever seen one for any type of alternator (many diesels have a one way pulley, which I suppose you could call a clutch, but it is mechanical only and so not switchable).

pic 2
If someone knows where I can find more precise info, then by all means LMK!
