I realize the bearing change might have been mandated by law, but the crankshaft change wasn't. And if the new bearings really are better than the old, then BMW would have chosen those to begin with instead of changing them after only 12 months of production.
Just my $0.02, and please keep posting BMRLVR.

Hmmm. I was under the impression these parts were the same since 2008. Good to know. Do you know in what month and year they changed these parts. Sorry if this has been discussed before.
