Engine

1.0L TFSI (3-Cylinder)

• High Oil Consumption
  • Description/Symptoms: Some owners have reported higher than expected oil consumption, requiring more frequent top-ups between scheduled oil changes. Symptoms include low oil level warnings and the need to add oil every few thousand miles.
  • Solution: Monitoring oil levels regularly and using the recommended oil type is crucial. In severe cases, a more thorough inspection of the engine may be needed to identify the cause of excessive oil consumption, such as worn piston rings or valve seals.
  • Estimated Cost to Fix: $50 - $150 (for oil and top-ups), $1,000+ (for major engine repairs if necessary)
  • Recalls: None Found

1.4L TFSI (4-Cylinder)

• Coil Pack Failure
  • Description/Symptoms: Misfires and rough running can be caused by a faulty coil pack. The check engine light may illuminate.
  • Solution: Replace the faulty coil pack.
  • Estimated Cost to Fix: $100 - $300
  • Recalls: None Found
