Alternator OEM Volvo or OEM BMW

My old 04 Volvo Xc90 had 311k on the dash before the alternator gave up lol. Doing better than that!

Had the same issue a few months back. Put in a new alternator and it’s been perfect since.

You need to try using a OEM REMAN or OEM NEW alternator. Aftermarket items can really affect BSD.

Those alternators are damn near bulletproof, it’s the voltage regulators that crap out. If it were me, I’d keep the OEM unit, replace the pulley, and swap out the voltage regulator while I was at it.

I have a 100A alt from a 900 series and it keeps me powered, but barely. And if I have the stereo loud + headlights and fogs and a/c, I get belt squeal.

My 540i at 141k started eating me alive, Alternator blew up
