The Mercedes slogan is 'Das Beste oder nichts' ('The best or nothing'). Mercedes diesels have long been known for legendary reliability, with German taxi fleets running to million-kilometre mileages. 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.
Stage 1 on Mercedes often requires refreshing the adaptations after the flash. Mercedes is one of the most protected brands in the chip tuning industry in terms of encryption. The Mercedes community in Europe has a large pool of available Stage files for the standard models. The Mercedes premium segment is a high-output platform with Stage 2 potential. High-output Mercedes engines are premium-class with solid headroom for Stage 1. On modern high-output Mercedes, Bench reading is often required because of the encryption.
