Engine
2.0L TFSI (Gasoline)
- High-Pressure Fuel Pump (HPFP) Failure
- Description/Symptoms: Extended cranking time, rough idle, lack of power, fuel smell, check engine light. Internally, the follower wears down and the pump can fail leading to metal shavings contaminating the fuel system.

- Estimated Cost to Fix: $800 - $2,000+ (depending on the extent of fuel system damage).
- Recalls: None Found
- Carbon Buildup on Intake Valves
- Description/Symptoms: Rough idle, misfires, decreased fuel economy, loss of power, check engine light. Direct injection engines are prone to carbon buildup on the intake valves since there is no fuel washing the valves.
- Solution: Manual cleaning of the intake valves (walnut blasting or chemical cleaning).
- Estimated Cost to Fix: $400 - $800
- Recalls: None Found
- Oil Consumption
- Description/Symptoms: Low oil level warnings, need to add oil frequently, blue smoke from exhaust in severe cases. Often caused by worn piston rings or a faulty PCV valve.

Summary
The 2012 Audi A3, while offering a premium driving experience, has its share of potential issues. Engine problems, particularly carbon buildup and HPFP failure in the 2.0T, and DPF/EGR problems in the TDI, are common and can be costly to address. The S-Tronic transmission also has known issues with the Mechatronic unit and clutch wear. Suspension and electrical issues, while less severe, contribute to the overall maintenance burden. Overall, potential buyers should be aware of these common problems and factor in the potential for higher repair costs when considering a 2012 Audi A3.
