Do you recall a definitive "aha" moment, as to the root cause of the HPFP failures, because I don't.

I think this is an important distinction. Yes, there are markedly less failures. But, I don't think the cause is fully understood.

Please correct me if I have this wrong.
All F30s got a redesigned fuel pump vs. what BMW used with pre-March 2012 E9x cars.

I've read thousands of posts here and elsewhere, and never seen anybody have a failure of this new design.
