2G Type S BOV problem

[Edmontes4g63]

hey guys so for some reason I can’t seem to find the right thread on here but for the past 2 days my cars BOV has been fluttering ever time I shift gears. It will do it at low boost and high boost. Not sure what’s going on with it. When I shifted gears it used to go pushhhh haha but now it just flutters. Any help would be appreciated. I work all day everyday just about so any kind of insight is much appreciated thanks!

Take it off and test it with a vacuum pump. Or disconnect both the outlet and take the vac hose off. Plug the intake. You can watch the valve move if you apply the vac hose and look into the outlet. The car will also start running poorly because you just opened a hole post maf. If the valve doesnt move the diaphragm is probably torn.
