  • Estimated Cost to Fix: $2,000 - $8,000+ (engine replacement)
  • Recalls: None Found
• Diverter Valve Failure
  • Description/Symptoms: Loss of boost pressure, resulting in reduced acceleration and performance. Can also cause a check engine light.
  • Solution: Replacing the diverter valve with an updated revision.
  • Estimated Cost to Fix: $150 - $400
  • Recalls: None Found
• Cam Follower Failure (High-Pressure Fuel Pump)
  • Description/Symptoms: Ticking noise from the engine, rough running, and a potential check engine light. If left unaddressed, can lead to complete fuel pump failure and engine damage.
