Disadvantages of the Honda N16A engine
- On specialized forums, they often complain about the vagaries of piezoelectric injectors.
- In engines of this family, it is recommended to change the fuel filter very often.
- The particulate filter quickly fails from bad diesel fuel, and replacement is very expensive.
Injectors are the main issue for DPF and EGR A and B problems.
I had 2 faulty injectors causing EGR filter and dpf malfunction. Changed them, cleaned the dpf in a specialized pressure machine and cleaned the EGR admission half sphere filter under the DPF. Now it works like a charm and has now 360000km.
Fuel filter is hardly accessible and 160hp models do not have manual fuel pump integrated, need to plug external pump after fuel filter change.
