    Hi, guys.

    Diesel BMW maniacs from BMW Club Russia need your help
    According to "Cold-climate version (S842A)" option, diesel BMW's are equipped with a "Heating Element", fitted on filtered air pipe (see picture below).



    Does anybody know, what the purpose of this element is? How does it work?

    P.S. sorry for my poor English

    Judging from HERE, it looks like a de-icing unit of some sort.

    Thats the heating element on the CCV
    The idea of this valve is to remove the gases from the top of the engine, separate the gases from a small amount of oil - gases go back into the inlet manifold, oil goes back into the sump via the dipstick tube.
    So I would assume its there to aid the seperation of oil and gases and to keep the oil thin and free flowing?

    Thanks, but IMHO, there is a special oil separator to separate the oil from the blow-by gases. It is situated in cylinder head cover. Mentioned heating element has other purpose.
