Е60/E61 bmw e60 smoke

Interesting why are you asking here? There are a lot of ENG forums in EU and US, where such issues were discussed many times. Anyway, it doesn't really matter)
I'd say that it's not white smoke, it is gray smoke. So it looks like your engine has huge oil consumption. What is your oil consumption for 1000 km? How much liters do you add oil per 1000?
If I'm right, then you should to repair engine. What exactly you should repair in this case, depends on diagnostics results. There could be a lot of different reasons

 

турбина масло гонит, как один из вариантов
либо кольца легли.

 

it is too much. You should find the source oil consumption and fix it (or change car). It could be from the turbine, or carbonized piston rings, or cylinder wall damage ... etc. Or even all together (it is not joke)
