Plastic coolant components, particularly the thermostat housing and water pump, are prone to cracking and leaking over time. This can lead to overheating and potential engine damage if not addressed promptly. Estimated repair cost: $500 - $1,500.

Ignition Coil Failure

Individual ignition coils can fail, leading to misfires and rough running. This is a common issue across many turbocharged Audi engines. Estimated repair cost: $400 - $800.

PCV Valve System Malfunction

The Positive Crankcase Ventilation (PCV) valve system can become clogged or fail, leading to oil consumption, rough idle, and potential vacuum leaks. Estimated repair cost: $300 - $700.
