one more question about my E39 525 TDS (April 1997).
I read a lot of threads on the web dealing with the possibility to easily
clean the AirFlow Meter without having to substitute it.
But I got also discouraging points of view, saying that once you remove it,
you might have problems to put it back and get it working fine again.
So my question is if it's difficult or not to make this cleaning on my
Maybe for some models it's more difficult / delicate than fir other ones.
Thanks for your inputs. Alberto
