Right. But as the OP (and tiago as well) from the post I linked noted, this noise somewhat recently started. I think on my car too, it started up a about 3 or 4 months ago - though I can't be certain it wasn't always doing it (I've had car for about 8 months).

If it was DI noise or this purge valve, noise should have been there from day 1, no?
