Disadvantages of the M47D20 engine
Several diesel models have intake flaps that can drop into the cylinders.
When the crankshaft pulley is destroyed after 100,000 kilometers, a branded engine failure occurs.
An ECU failure is frequently caused by the power unit’s prolonged overheating.
Although it depends on the quality of the oil used, this fuel system is dependable.
Crankshaft failure and oil starvation are caused by using subpar lubricant.
