I Have a 2010 Bk1 2.0t and all I have done to it is a CAI w/ a test pipe and Axle back. I’ve had the CAI Intake on my car for 2 months now. It recently started making this really bad sound when it’s spooling when I give it gas to accelerate. It’s sounds like the Wastegate is sticking open or closed? I don’t know. and it’s not building boost properly. I’ve taken out the solenoids and sprayed them with Wd-40, and them back in. I know with the stock bov and silencer delete the car is makes a noticeable noise when spooling. But Trust me, this noise is completely different then that. PLEASE HELP THIS REALLY FRUSTRATING!
