One of the most common failures on the 2.0T FSI engine is the factory pressure-relief valve. These valves are in place to recirculate crankcase gases into the intake manifold once they open. Although this works fine for a few thousand miles, they begin to leak over time and cause boost to go past the valve into the valve cover. This not only causes an oily mess in the engine bay from crankcase pressure, but a rough idle, fuel economy decline and boost loss. With boost pressure far below where it should be, it is common to notice significant power losses and poor drivability.
