The 1995 generation — first-generation CDI/TDI/HDi diesels with relatively simple ECU protection; OBD reading works directly.

Mercedes-Benz is the world's oldest carmaker, founded in 1926 by the merger of Daimler-Motoren-Gesellschaft and Benz & Cie. The Mercedes slogan is 'Das Beste oder nichts' ('The best or nothing'). Smart is Mercedes's city sub-brand, historically running Mitsubishi and Renault engines. Mercedes pioneered CDI (Common-rail Direct Injection) technology on passenger-car diesels, in series production since 1997. Mercedes diesels have long been popular with the German police and taxi services. Mercedes diesel engines are fitted to passenger cars and commercial vehicles.

The Mercedes community in Europe has a large pool of available Stage files for the standard models. Stage 1 on Mercedes often requires refreshing the adaptations after the flash. In the Mercedes commercial segment, Stage 1 focuses on torque. Top AMG engines sit at the Mercedes power ceiling, and the gain is significant. AMG engines are a well-known base once hardware is added (downpipe + intake + intercooler). Brabus is a premium alternative to AMG for the top models. AMG Performance Studio is Mercedes's in-house tuning studio for bespoke projects.
