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.
