|
Known Issues
|
Diesel Particulate Filter Dpf:
|
Potential for DPF clogging or regeneration issues if the vehicle is primarily used for short trips with insufficient driving cycles for regeneration.
|
Exhaust Gas Recirculation Egr:
|
EGR valve can become clogged with carbon deposits, leading to reduced performance and check engine lights.
|
Fuel Injectors:
|
Diesel injectors can be sensitive to fuel quality; issues may include poor starting, rough idle, or reduced power.
|
Glow Plugs:
|
Glow plug failure can lead to difficult cold starting.
|
Turbocharger:
|
Like any turbocharged engine, potential for turbocharger wear or failure over time, often indicated by loss of power or excessive smoke.
