Known Issues
2.0 Tfsi Oil Consumption:
Early B8 2.0 TFSI engines could exhibit higher than normal oil consumption due to PCV system or piston ring design. Later revisions and proper maintenance mitigate this.
Pcv Valve Failure:
Failure of the Positive Crankcase Ventilation (PCV) valve can lead to oil leaks, rough idle, and increased oil consumption.
Water Pump Leaks:
Some models may experience coolant leaks from the water pump, especially as they age.
Thermostat Issues:
Thermostat housing failures can lead to coolant leaks and temperature regulation problems.
Timing Chain Tensioner Wear:
While designed for longevity, extreme mileage or poor maintenance can lead to tensioner wear and potential chain noise.
