Disadvantages of the Q4BA engine
- This diesel engine is considered reliable, but very difficult to maintain and repair;
- A modern fuel system with piezo injectors does not tolerate low-quality fuel;
- In addition, to dismantle the nozzles, equipment is required to drill them out;
- A lot of problems for owners are caused by a capricious Bi-Turbo system;
- The remaining breakdowns are associated with contamination of the EGR valve and particulate filter.
