For instance, a diesel engine designed for European markets might have a different fuel injection system or turbocharger compared to one designed for Asian markets. These differences are often reflected in the OSC and SCSC codes, allowing you to identify the exact components used in your engine.

Moreover, diesel engines are subject to stricter emission regulations in many countries, leading to variations in the exhaust gas recirculation (EGR) systems, diesel particulate filters (DPF), and catalytic converters. The SCSC code will tell you which emission control systems were installed on your vehicle to comply with the regulations in its original market. This is crucial when you're replacing parts or troubleshooting emission-related issues. Another reason why these codes matter for diesel engines is the potential for fuel quality variations. Diesel fuel quality can differ significantly from country to country, and Nissan might have made adjustments to the engine's fuel system or injection timing to accommodate these variations. The OSC and SCSC codes can help you determine whether your engine has been specifically tuned for a particular fuel type. In addition, diesel engines often require different maintenance procedures and intervals compared to gasoline engines. The OSC and SCSC codes can provide valuable information about the recommended maintenance schedule and the types of fluids and filters that should be used in your engine. So, whether you're a mechanic, a parts supplier, or a Nissan sedan diesel owner, make sure to pay close attention to the OSC and SCSC codes to ensure you're getting the right information and parts for your engine.
