Disadvantages of the Q4BA engine
Although this diesel engine is thought to be dependable, it is quite challenging to maintain and repair;
Low-quality fuel cannot be tolerated by a contemporary fuel system with piezo injectors;
Additionally, equipment is needed to drill out the nozzles in order to disassemble them;
An unpredictable Bi-Turbo system causes a lot of issues for owners;
The remaining malfunctions are linked to particulate filter and EGR valve contamination.
