Valvoline R&P Stops BMW Oil Consumption

[f355spider]

a member there,in that discussion refers to the "BavarianE39 CCV mod" that fixed his problem with the consumption.

what is that ? does it work?

Its a catch can. Google "BMW M54 catch can" will probably find a ton of information and threads on the subject. Very common issue on BMW 6 cylinder engines...perhaps others.
