Today i am showing you how i replaced the voltage regulator on my 2009 bmw 135i with the N54 engine. Very simple fix and can solve lots of electrical issues. Save money by replacing just the regulator instead of a new alternator.

That's definitely not something I would have thought of, but I'm at over 160K miles, so mine could probably use a refresh (never had my alternator replaced).
How many miles did that alternator have on it, for reference ?
