Disadvantages of the Porsche M55.01 engine

  • This is a direct injection unit and often suffers from carbon deposits on the intake valves.
  • The weak point of the motor is the abundance of plastic parts in the cooling system.
  • An air-oil separator or a PCV valve is distinguished by a low resource.
  • The timing chain serves about 150,000 km, and the replacement is carried out on a removed engine.
  • Ignition coils, the pump in the tank and the water pump also regularly fail.
