Exhaust Emissions
The V6 OM656 engine has complex EGR systems that tend to accumulate soot and carbon deposits, especially with city driving and frequent short trips. Clogging can cause rough idle, power loss, smoke, and a check engine light; the solution typically requires cleaning (carbon removal) or replacement.
Exhaust Emissions
The latest generation Common Rail system (CP4 high-pressure pump and piezo injectors) is sensitive to fuel quality and contamination. Water or foreign particles can accelerate wear, leading to injector failures or pressure loss, resulting in power loss.
Fuel System
Turbocharger failures, wastegate solenoid issues, or vacuum leaks in control hoses can cause boost loss, error codes, and sudden power drops under load.
