My Ride: 2002 325Ci
I am just about to attempt this on a 2002 325Ci, does anyone know if this car has the bosch or the valeo? Also I was looking at the regulator on partsgeek and it shows 2 different regulators that appear to be the same thing, does anyone know the difference between the top 2


I get about 11V while the car is running, and about 9V when the car is off, but the battery is dead. No noise from the alternator, so I'm pretty sure it is just the regulator.
