Most common problems, symptoms & fixes for the CDUD engine.
Engine CDUD commonly faces issues like carbon buildup on intake valves, EGR valve clogging, and turbocharger wear. Diagnosis involves checking for rough idling, loss of power, or increased fuel consumption. Use a diagnostic scanner to read 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 intake system cleaning. Solutions often require cleaning or replacing the EGR valve, performing intake manifold decarbonization, and inspecting or replacing the turbocharger if worn. Maintaining the intercooler and ensuring proper air filtration also helps prolong engine life.
