Disadvantages of the M47D20 engine
- A number of diesel versions are equipped with intake flaps that can fall into the cylinders
- A branded engine failure is the destruction of the crankshaft pulley at 100,000 km
- Prolonged overheating of the power unit often results in an ECU failure
- The fuel system is reliable here, but demanding on the quality of the oil used.
- The use of poor-quality lubricant leads to oil starvation and crankshaft failure.
