Audi A4 (2018 - B9-FL) 40 TDI (2.0) 190 hp — premium diesel engine of the passenger segment of the Volkswagen Group (VAG) group (Германия, 1909). Stage 1 chip tuning raises power from 190 to 225 hp (+35 hp, +18%) and torque from 380 to 460 Nm (+80 Nm). This engine ships with different ECU variants: Bosch MD1CP004, Bosch MD1CS004. The flashing method is determined by the specific unit: OBD, Bench or Boot mode. In the CHIPOK database: 2 configurations · 2 ECU variants. A modern diesel built in 2018 — a generation with encrypted firmware (Tricore TPROT) that often requires a Bench read.
The Audi community is one of the most active in Europe for chip tuning. The e-tron line is Audi's EV range within the VAG group. Audi is part of the Volkswagen Group (VAG), Europe's largest automotive group. Mid-range Audi diesels are a mainstream chip tuning subject across Europe. The Audi diesel range is fully unified with Volkswagen, Skoda and Seat within VAG. On modern Audi diesels, the Tricore TPROT protection often requires a Bench read.
