Disadvantages of the FA24 engine
Since this power unit is new, not much is known about its malfunctions;
This engine has high fuel quality requirements, just like all direct injection engines;
Phase shifters won’t last long if you don’t strictly adhere to the oil recommendations;
The units in this series keep an eye on the cooling system’s condition because they fear overheating;
We are awaiting a new firmware, but floating idle speeds have already been discussed on specialized forums.
