You believe it does because you want it too. FML.

Bmw knows what the cause is. It's probably too small a bearing and they literally can't do anything about it. That's why there is no clear fix and everyone is trying their damdest to work with the crap they CAN change (clearances, coatings, viscosities, etc).
I'm of the opinion opening up the clearances helps make up for the bearings being too small. |
Smaller(thinner) bearings increase clearance. Bigger (thicker) bearings decrease clearance.
BMW doesn't know. They look at the technical data and don't see a problem. They just blame the user of abuse.
