By the way, the VW DI TDI pump is also from Bosch... So if the conclusion was improper lubrification because of poor quality fuel hummm chance are BMW design and lubrification spec of the pump is similar...
Also it is a major question to ask if this plague is focused in USA, yes I know their is more 335i/135i sold in USA than any place in the world. But if this issue is anecdotic outside USA, than a local parameter proper to USA could be the cause.
