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.
For hpw old your car is, and the price of these boys in the photo, id go to your local autozone and get their alternator, simply because they come with a lifetime warranty
I want to hear an opinion on getting a duralast alternator and popping it in my n52 I have heard very mixed things about these parts some work fine others are trash.
A bearing went in our original alternator so I replaced it with a Valeo brand and it's pretty loud when it clicks on. It is loud enough that I'm wondering if I got a bad alternator --or is this normal??
It's the typical whirl or whurr noise --it's silent, and then you can hear the whirl or whurr noise when the alternator clicks on. It seems mechanically and electrically fine: It's doing what it should be doing electrically (charging, correct voltage, the battery is happy, the car runs better with this new alternator, etc.). It's just loud.
Wouldn't recommend AutoZone based on my experience. Had a duralast gold fail on me and had to get a replacement one.
Made the mistake of buying the duralast, first one lasted a couple months, and the second one is dying, only charging the battery at highway speeds, just like the first one before it died.
We have a lady with an infinity that comes in once a year to get her duralast alternator replaced.
I bought a Duralast for my ‘99 E55 a few years ago. It didn’t work so I pulled the rectifier off of it, put it on the original one, which put out at 14.2 v back in the car. I returned the Duralast one after I made the old rectifier look like new. The shaft rotation on the Duralast felt gritty, too.
