My wife and I went to eat not too long ago, and little did I know I was not going to make it back soon.
You see my car gave me a battery warning on the way there. I knew my battery was low, I have an app that can monitor that, but because I don't drive my car as often as I use to, it often took a bit of freeway driving to "recondition" the battery, and so I kept going. On my way back my E90 200 330i didn't want to go any more, I ended up getting towed back home.
Next day I got a replacement Alternator from my local Autozone, they had a lot to select from, the most important part was making sure that it was 180A alternator from Valeo, which they did.My Alternator was $150.00
So I set out to replace it, and to my surprise it was the most simple service I have done to my car. I only had to remove the Air intake box and I had access to all.
I pulled the belt off it and I un did the 4 screws holding it, I loosen the 1 connector and 1 (hot) red wire, then out it came. I put the new one in and put everything back and that was it.
Very simple to remove and replace.

| Make sure to disconnect the Negative from the battery before you start working on the car |
 |
| After you remove the intake air box, you have good access to the 4 screws to remove the Alternator |
 |
| Replacement didn't come with Pulley, make sure you save it from the original |
 |
| Pulley removed |

| Old alternator with pulley |
 |
| I think it failed because it had all this "oil" with dirt and it didn't vent right, eventually it overheated I think |
 |
| Connection cable unplugged |
 |
| To charge the battery back up I left it charging overnight |
I hope this was helpful to you!
