Most common problems, symptoms & fixes for the CDUC engine.
Engine CDUC is known for issues such as carbon buildup on intake valves, EGR valve clogging, and turbocharger wear. Diagnosis often involves checking for rough idling, loss of power, or increased fuel consumption. Use diagnostic tools to scan for fault codes related to the EGR system and turbo performance. Prevention includes regular use of high-quality fuel, timely oil changes with manufacturer-recommended oil, and periodic cleaning of the intake system. Solutions involve cleaning or replacing the EGR valve, performing intake manifold decarbonization, and inspecting or replacing the turbocharger if necessary. Maintaining the diesel particulate filter (DPF) also helps prevent related engine problems.
