Land Rover found something wrong with the diesel version 4 idling after parking.

Dirty, worn and improper installation of mechanical parts lead to changes in the power of individual cylinders, resulting in unbalanced power of each cylinder, unstable engine idle speed, abnormal engine electronic control system, poor combustion of mixed gas, difficult power balance of each cylinder and unstable engine idle speed;

Too much carbon and dirt are deposited in the throttle and the surrounding air intake, and the cross-sectional area of the air passage changes, which makes the control unit unable to accurately control the idle intake, resulting in the mixture being too rich or too thin, resulting in abnormal combustion;

The fuel pressure is too low, which directly leads to the fog of sprayed oil and poor spray quality. In severe cases, only some oil droplets appear at the oil injection port. The main performance is that the mixture is discharged too thinly, which leads to unstable idle speed and low speed of the engine, often accompanied by fire.
