Boost Question

[FREAK_SHO]

2015 non PP Aprox. 84k all service up to date. No service light. Will be checking for codes.

Under boost conditions, it sounds like it is building then dumping boost. Bit of a hesitation during this.

Question(s) - boost leak? Bad waste gate? A need to drain the CAC? All the above? Or?

Just looking for thoughts from those who may have encountered this same issue.

Thanks,
David

With that many miles, check the plastic piping at the turbos. They usually start to crack. Also could be a tear in the factory bov. Remove both of them and pull the valve out lightly and inspect the orange rubber diaphragms for tears. I just met up the other week with a member to help him with his and the bov was the issue

Look at/cor the c-clip that holds the wastegste actuator rod to the wastegste. They pop off.

Follow up- thanks to those who responded. I did find a few loose clamps, didn't see blow by but...c-clips were good. What I found, boost solenoid had come off the charge pipe ( I believe ), quick reconnect and zip later, back to normal.
