Bought a used Valeo alternator, and sure enough, the charging problems went away, and it starts charging as soon as I start the car.
Pros: charging problems resolved, starts charging immediately
After more trouble shooting I felt that the alt needed replacing and not just the rebuild kit. After removing the unit (what a PITA)... Ended up buying a RMMAL00134 Reman by Magneti Marelli for around $140 after tax and shipping. Went in without any problems and completely fixed my issue.
Pros: fixed the issue, went in without problems
Vehicle:
Volkswagen Passat
Part number: RMMAL00134
I will always vote for a 10SI or 12SI GM alternator swap on an L-series engine. Affordable conversion bracket. 1-wire GM alternators are simple, reliable, cheap and readily available online but not easy to find in parts stores. 3 wire GM alternators are are easy enough to wire up and are absolutely everywhere in parts stores if you’re more concerned about parts availability and potential breakdowns on long adventures.
Pros: simple, reliable, cheap, readily available
Cons: 1-wire not easy to find
90% is the alternator: get a reman Bosch. The "squeaky serpentine belt" is actually the bearings inside the alternator on their last legs.
Pros: remanufactured Bosch recommended
I needed a new weather strip (DIYed with a $30 part off Amazon) and a new alternator ($400, could have DIYed but didn’t have time to wait for a part to ship).
Pros: DIY weather strip
Cons: expensive alternator
Vehicle:
Toyota Corolla

Cons: battery can fry alternator
Vehicle:
BMW
Mesmo um Valeo novo está caríssimo, pede mais orçamentos.
