Disadvantages of the DW12CTED4 engine
- The disadvantage of this motor is its rarity.
- The main trouble is delivered by the particulate filter, which is very often clogged.
- Also, errors often occur here due to under-blowing or over-blowing of the turbine.
- Piezo injectors not only quickly become clogged, but are also dismantled with great difficulty.
- The rest of the problems are related to the violation of the fuel filter replacement schedule.
