Problem overview
This engine (2.0L FSI) uses direct injection which requires very high fuel pressure. This high fuel pressure is achieved by using a high pressure mechanical fuel pump (HPFP) that is driven off of the camshaft.
The HPFP may fail due to damage from a camshaft manufacturing defect. The defect causes abnormal wear of the mechanical barrier between the camshaft and the fuel pump. This barrier, the cam follower, will wear down and cause failure of the camshaft and the HPFP.
Symptoms include illumination of the check engine light, engine running roughly, and loss of power. Engine codes associated may be P0300, P0301, P0302, P0303, P0304, P0087, P1093 and P2293.
To correct this issue one or all of the following will need replacement: the camshaft, high-pressure fuel pump, and/or the cam follower.
To help prevent this issue from occurring, the cam follower should be inspected every 10,000 - 15,000 miles.
