Yesterday I replaced my 90A B brand alternator (thank you, previous 8 owners) with a Valeo 120 Amp unit. So far seems to be working fine with 14.15V to the battery at idle and with minimal or max power draw.
Id go with whatever fcpeuro recommends. Aka valeo, bosch (which are both oems)
I just did a standard exchange on mine (Valeo 120A), paid 300€ deposit included, so it's definitely a good deal.
Only the NEW valeo or original BMW alternators last in these cars.
My alternator went and I never had any lights, just weird electrical gremlins and batteries dying. Replaced it myself, took maybe 2 hours and the part was like $150 after the core return
Both Valeo and Bosch are good brands. I’ve never owned a Mercedes, but both Valeo/Bosch are installed in various BMWs from the factory.
Sometimes when u replace the alternator but the battery is bad it'll just fry your new alternator.
I bought a new Valeo alt cheap because this part was broke. After days os scouring the internet I found two sources, but the would NOT retail the part. They only supply rebuilders in bulk.
Actually, yes. I did. They did take it back though, after a couple of phone calls.\n\n+1 for Valeo. -10 for Reman.\n\nIf your alternator goes, absolutely get a new one, original spec.
I ended up getting a new one from BMW after two remans failed with once catastrophically failing and catching fire almost burning up my car.
