I have a 2012 2.0T and my BOV is always open. It appears as if the solenoid I believe it’s called that the BOV is connected to, has vacuum all the time causing the BOV to stay open. If I disconnect the BOV from the solenoid, it holds boost if I am light footed but if I push it , it opens again. I disconnected the solenoid from power and still get the vacuum. What should I look at replacing to get this going?
