Traveling down the highway in limp mode I can max speed about 72 mph. I have a 16683 under boost code. If I clear the code while driving, I get about 10-25 seconds of boost until it lays flat again. I shot a video of this but I don't know how to post it on here. I did this repeatedly on a 150 mile trip. Any time I needed to pass someone I just cleared the code and took off. It was like having my own little turbo boost button. Because of this, I am convinced there are no boost or vacuum leaks, and the turbo vanes are not sticking. I had also applied vacuum to the turbo, and I get full range of motion on the actuator. Am I down to the only possible culprit being the N75 Pressure Converter? 2004 Passat BHW. Thoughts please.
