Disadvantages of the A28NET engine
Keep an eye on the cooling system because this turbo engine overheats easily.
Timing chains are a very limited resource, and it will cost a lot to replace them;
Air leaks from the air filter frequently occur through the pipe;
Here, the wastegate membrane frequently bursts, but the turbine is dependable;
The unit’s vacuum, gasoline pump, and control unit are its weak points.
