Hi again! I don't remember exactly how the intake tubing and piping is arranged in your engine bay but if it looks something like my MK6 GTD there is a combination of pipes and connections from the turbo via intercooler and up to the intake. On my car, the pressure side of the turbo (where you want to look) is on the right side when facing the car from the front. Here you can follow the piping around the engine and down to the intercooler which is mounted low in front of the radiator. From the outlet on the left side of the intercooler you can follow the last bit up to the intake.

So, first of all I suggest you check if any of the pipes are loose or misplaced/not connected. Then check or change all the clamps along the piping described above.

If all seems good, try testing your turbo actuator as well. The rod could be prevented from working as normal which gives uneven pressure readings. Disconnect the pressure hose on the top of the actuator and connect a bicycle pump or something to the niple to use as a pressure source. Then see if the rod moves in a smooth motion.

Hope some of this helps and that you figure out the problem. If not, I'am sure there are someone here on the forum that are more experienced than me who can give you some helpfull advise!
