  • Description/Symptoms: Some owners report higher than normal oil consumption, requiring frequent top-offs between scheduled oil changes. This can be a gradual process, becoming more noticeable as the vehicle ages. Symptoms include low oil level warning lights and the need to add oil more frequently than expected.
  • Solution: The Audi technical service bulletin (TSB) addresses oil consumption issues. Some dealerships may perform an oil consumption test to assess the severity. Repairs can range from replacing the PCV valve and breather hoses to piston ring replacement which is the most common solution.
  • Estimated Cost to Fix: $1,500 - $7,000+
  • Recalls: None Found
• Turbocharger Failure
  • Description/Symptoms: Reduced engine power, unusual whining or whistling noises from the engine bay, and/or a check engine light. This could be due to a failed turbocharger or wastegate.
  • Solution: Diagnosis to confirm turbocharger failure, followed by turbocharger replacement.
