The Positive Crankcase Ventilation (PCV) system can fail, leading to increased oil consumption and potential vacuum leaks. This is a common area of concern for this generation of Audi engines. Estimated repair cost: $400 - $800.

Excessive oil consumption is a known characteristic for some 2.0 TFSI engines of this era, often linked to PCV system issues or piston ring wear. Regular monitoring and top-offs are crucial. Estimated repair cost: $500 - $1500+.

Potential for coolant leaks, particularly from the water pump or thermostat housing, can lead to overheating and engine damage if not addressed. Estimated repair cost: $300 - $700.
