hello i own a S40 2009 2.0D (PSA/FORD) car,
and it seems to be more and more noisy, i have a rolling noise in gear and at 2200rpm even in neutral it is verry anoying,
at first i had this sound only in gear at about 1800rpm and more but now it starts a 1600rpm and event in neutral at 2200rpm.
my volvo s40 2009 2.0D (136ch) has been smoking white smoke from the engine bay (and exshaust).
It occurs when its cold ( minus 4 degrees ) and at idle, the motor start to be verry dizzy and it shake a bit.
PS : it smells like oil.
i dont know where it come from it is very random...
