I bought a used 2016 VW Jetta TSI with the 1.4L engine. There is almost no information online for this! I bought CRC GDE Intake Valve and Turbo Cleaner but not sure how to use it with this engine. It doesn't appear to have a MAF and I don't know which is the brake intake manifold vacuum line on this vehicle, so I'm unclear where to spray this. I see there is a vacuum hose to the intake somewhere underneath the intake filter box. The air charge system pipe from the air filter box goes to the turbocharger and some return to the intake, and that would be easy to access, but it doesn't seem the best option given the instructions I've read from the can or on your video for this cleaning process.
BTW, this car has a bit over 115k miles on it.
You can screw things up on that turbo if you don't do it right. Personally I would advise you just to put an intank cleaner and not mess under the hood on that turbo Volkswagen
