    For anybody who may have such an engine in their 5 series,
    and find that it smokes out of the exhaust.Quite badly if left on
    tick over for a while.

    There is,on each bank,front end under cover.a Diaphragm.
    These Diaphragms do not last very long,and with the smoke
    coming from back of car,you think it will cost £££££'s.Infact
    in England it does for the parts,the job is a DIY.

    I have now found instead of the £30-£142 each that you
    can buy in China/Hong Kong for under a fiver each.These though
    cheap will last longer because the spring under diaphragm is not
    as strong,So by having weak spring it is a win win.


    :D:D:thumbsup: :cool:
