Mercedes S (2021 - W223) 400d (2.9) 330 hp — premium diesel engine of the passenger segment of the Mercedes-Benz Group AG (Mercedes-Benz, AMG, Maybach, Smart, EQ) group (Германия, 1926). Stage 1 chip tuning raises power from 330 to 400 hp (+70 hp, +21%) and torque from 700 to 800 Nm (+100 Nm). This engine ships with different ECU variants: Bosch MD1CP001, Bosch VGS3-NAG3. The flashing method is determined by the specific unit: OBD, Bench or Boot mode. In the CHIPOK database: 2 configurations · 2 ECU variants. A 2021 diesel — a modern platform protected by RSA + checksum encryption; top models require BDM/JTAG.
4MATIC all-wheel drive is Mercedes' signature system, fitted to most models. The Mercedes-Benz Group AG (Daimler AG until 2022) comprises Mercedes-Benz, AMG, Maybach, Smart and the EQ line. AMG is the performance division of Mercedes (since 1967), building engines on the 'one man, one engine' principle in Affalterbach. The factory calibration on Mercedes diesels is conservative, leaving headroom for Stage 1 while preserving engine life. DPF/SCR with AdBlue is standard on all Euro-6 Mercedes diesels. On modern Mercedes diesels, the encryption often requires Bench reading or authorised OBD.
Stage 1 on Mercedes often requires refreshing the adaptations after the flash. On modern Mercedes, the encryption requires specialised Bench tools. In the Mercedes commercial segment, Stage 1 focuses on torque. On modern high-output Mercedes, Bench reading is often required because of the encryption. 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.
