So in my 08' 535xi I have been intermitently experiencing these bouts where the car has zero boost and no codes unless I try to go wot, in which, I get the 30ff underboost code. I've checked the vacuum canisters, lines, diverters, etc but I don't think this is a leak.
Anyone have any similar experiences? The car runs great, has a slight misfire at idle but doesn't throw any codes for it and runs absolutely fine and smooth apart from not having any boost. The misfires at idle come and go periodically furing driving. At one light it'll miss a little and the next not at all.
Thanks!
