The last time I did this was on a Toyota about 15 years ago and it was just attached to the end of the alternator. But FCP has a bunch of "decoupler" tools in their section for the alternator. Just want to check before I take the car apart.
Edit: Nevermind, it appears you can access it on the back of the alternator if you take it off.

Valeo 220A and the same part number for my 2011 35d.
The decoupler is a overrunning or clutched pulley that diesels should have on their alternators. INA, BMWDieselParts, and Litens all make the correct pulley. I plan to use a Litens when I rebuild mine. These type of pulleys require a tool, not exactly a tool, but a technique to remove the pulley. Basically a socket with wrench flats and a hole to pass the Torx bit through.
