Disadvantages of the A28NET engine
- This turbo engine overheats quickly, so keep an eye on the cooling system;
- Timing chains have a very modest resource, and their replacement will be quite expensive;
- It is very common for air to leak through the pipe from the air filter;
- The turbine is reliable here, but the wastegate membrane often bursts;
- The weak points of the unit include its control unit, vacuum and gasoline pump.
