View Full Version : b7 loss of power

12-13-2012, 11:04 PM
i have an 08 b7 2.0t and it sounds like my bypass valve was leaking because it sounded like it was blowing air out even at idle and under acceleration. if i accelerated and at certain rpms and let off it almost sounded like a quite bov anyway i just replaced the bypass valve myself and the CEL but i have no power and feels like i have no boost.????? also i have lots of oil blow by so i think my pcv valve could be going out but wanna know about why i have no power. answers would be appreciated. Thanks!

Is there any lights on? Idle rough? No acceleration?
