BOV problem - BMW 3-Series (E90 E92) Forum

brosey88 · 02-20-2013, 10:37 PM

Hey guys i just bought an active autowerkes charge pipe and BOV. while under WOT it doesnt sound like the BOV is opening. with just regular driving i hear it open fine but when i do pulls it doesnt seem to open correctly. not sure what the issue is.

Dobyou have a tune? Because what youre describing sounds like the bogfix feature that keep some psi during shift to make shifts smooth.

If this only happens under heavy load it is usually normal, I thought I had the same problem a while back but that's just the way it works for the most part above 5k rpms

I'm running cobb stage 2+fmic with the AA bov and mine is loud as hell at wot and still pretty loud during normal shifting. I mean loud. So something is off.
