The Bentley manual* doesn't cover the M21 engine and sifting through the archives on either MyE28 or the Yahoo 524td Group can be frustrating to say the least. Ideally, this sticky will serve as a central repository for all 524td specific repair material. I hope these resources prove to be as invaluable to you as they have been to me.

*The Bentley manual is great for any repairs that are not unique to the 524td/M21. Even though it does not cover the M21, this manual should be part of your library for all of the generic E28 upkeep you will inevitably need to do.
