Mmmm it wouldn't happen to sound like this would it, when you opened the oil cap? cuz i think we found our problem. The pulsating noise stops after i open the oil cap, but comes back when i close it.
Also i don't know if they really matters but i forgot to mention that, when i got my car serviced at BMW a couple of months ago, they replaced some sort of heater, is it the PCV they replaced?
