Known issues and risks
Listed from most frequently reported, each with its source.
Faulty ignition coils and spark plugs (misfires)
Often reported
In the second-generation 2.0 TFSI (including S/TTS 272 HP version), faults in ignition coils and secondarily in spark plugs are common. Typical symptoms include irregular firing (misfire), check engine light, power loss, and vibrations at medium to high loads.
Engine Bay
Oil consumption and leaks (PCV/turbo seals)
Often reported
Many 2.0 TFSI owners report higher than normal oil consumption and leaks from gaskets (valve cover, PCV hoses) or turbocharger seals. A clogged PCV system can increase crankcase pressure, drawing oil into the intake manifold.
Engine Internal
High-pressure pump and injector failures
Often reported
Many TFSI units report failures of the high-pressure fuel pump (HPFP) and individual injectors; this can cause power loss, vibration, hard starting, and fuel system fault codes. HPFP failure may require a costly replacement.
Fuel System
Diverter valve / wastegate and turbocharger issues
Often reported
Supercharger system components such as the diverter valve or turbo actuator/wastegate can fail or lose calibration, causing abnormal whistling sounds, boost loss, and diagnostic fault codes.
