1.8 Liter Turbo engine
Have the car scanned for fault codes. A power loss in a turbo motor can be caused by simple vacuum leaks. You can check for loose piping and clamps. There are various components in that car that could cause such a problem. These include the turbocharger itself, the turbo boost (N75) valve, wastegate and its linkage, the car's ECU, maybe even a non turbo fault like a clogged catalytic converter or vehicle misfire.

Don't know much about VW but if it's fine, and it doesn't happen again I wouldn't worry about it. If it does try resetting the ECU by removing the battery terminals and touching the positive lead(red wire) to the negative battery post. It might spark a little, this is just the capacitors discharging, resetting your ECU and starting over. It's like restarting your personal computer

you need to write these down,have someone clear the codes in the car,then go for short ride and recheck which if any code reappears.it's like domino's affect,one sensor can start a chain affect with the others.
