Most common problems, symptoms & fixes for the CAYC engine.

Engine CAYC commonly faces EGR valve clogging and turbocharger issues due to soot buildup. Diagnosis involves checking for error codes related to EGR and turbo performance, and inspecting for reduced power or rough idling. Preventive measures include using high-quality fuel, regular oil changes, and periodic cleaning of the EGR system. The diesel particulate filter (DPF) requires proper regeneration; avoid frequent short trips to prevent clogging. Solutions often involve cleaning or replacing the EGR valve, servicing the turbocharger, and performing DPF regeneration or replacement if necessary. Timely maintenance ensures longevity and optimal performance of the CAYC engine.
