Timing chain
In modern diesel engines, the EGR valve can become clogged with carbon deposits, worsening the air/fuel mixture, increasing particulate emissions, and making the DPF regeneration process more difficult.
Exhaust Emissions
The 1.5 BlueHDi engine can experience DPF clogging, especially with city driving or short trips that prevent full regeneration. Software updates may be required for proper diagnosis of emission control systems (DPF/SCR) or monitoring strategies may need adaptation.
