So one thing I forgot to mention, some of the E70 have NO WAY to warn the driver if the charging system has a problem!!!

I know for sure many if not all of the V8 engines have this problem, not sure if other engines are the same. There may or may not be a software update or maybe this problem is a MASSIVE oversight by BMW. You can remove the serpentine belt and you will receive NO warning that there is a charging problem. You will get a low battery warning if you are sitting and using accessories, but I never received a low battery warning when the alternator was not charging.

What engine do you have in your vehicle?

Will be interesting to see what happens coming right of the charger.
