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.
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.
I had to buy a replacement remanufactured alternator (Valeo 120A one) and it was a straight replacement that solved the problem.
12-plate Fiesta, 106k miles
- Alternator is intermittent
- Rear bushes are audibly fucked
- Radiator fan packed up so it overheats when idling in warm weather
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.
It's probably a crap reman one. The aftermarket reman ones that aren't Valeo, Bosch, or Delphi seem to last a year tops before they die.
My neighbor had a Ford mustang and he had to jump start it about once a week. I checked the alternator and it had power when the car was off. Bad diode.
