I dont think any fuel pump gets it's lubricity from oil or any external system, the pump gets it's lubricity with the additive present in the fuel.
With the Vw TDI Bosh DI pump, the lubricity spec of the diesel in USA was lower than the lubricity spec needed by the pump, so they explode while in other country with "better" fuel they work perfectly. Some people in USA are now adding additive and it helped a lot.
Maybe they mix Ethanol or other crap in your fuel and lubricity isn't verry good.
All this scares me, I was in the market for a used 335i... but shit an older 330i with more milles worth more than a 335i, it make you wonder what the hell is going on with the 335i.
I will probably buy a slower R32 or an Audi A4 or worst case scenario a G35 coupe unless they find a permanent solution soon for this.
Good luck with this I imagine how you can feel about this... Sorry for my poor english.
