If its a 1.8t it could possibly be the POS (power output stage) on top of the air cleaner box. It controls spark on all cylinders and usually goes bad arround 80-100K miles. Unfortunately its a $450 part. You can check it with a test light- Unplug the engine side connector then have someone try to start the car. Try each terminal with the test light while trying to start the car, each terminal should flash.
