For the record, yet another person (this time on an E46 M54 engine) posted an idler roller that simply fell off the centerbolt, unbeknownst to the owner:
- E46 (1999 - 2006) > Alternator replacement with deflection pulley surprise.

Other related threads show why the idler roller is replaced along with the belts & tensioners:

E46 (1999 - 2006) > Another Possibility of a P00128

- E39 (1997 - 2003) > Mechanical Fan Exploded! Is another one
