Audi A4 (2004 - B7) 2.0 TFSI 200 hp — premium petrol engine of the passenger segment of the Volkswagen Group (VAG) group (Германия, 1909). Stage 1 chip tuning raises power from 200 to 240 hp (+40 hp, +20%) and torque from 280 to 360 Nm (+80 Nm). This engine ships with different ECU variants: Bosch MED17.5, Bosch MED9.1, Bosch MED9.1.x. The flashing method is determined by the specific unit: OBD, Bench or Boot mode. TCU units on this engine: Temic DQ250C, Temic DQ250E, Temic DQ250F — each is calibrated with a separate file (torque limiter, shift maps for Stage 1). In the CHIPOK database: 6 configurations · 6 ECU variants. A petrol engine built in 2004 — the era before widespread firmware encryption, OBD flash without complications.
Audi's petrol range is badged TFSI, and the diesel range TDI. quattro is Audi's signature all-wheel-drive system, introduced in 1980. The four rings in the Audi logo are a legacy of the 1932 Auto Union merger of Audi, Horch, DKW and Wanderer. The MQB and MLB platforms allow ECU commonality with Volkswagen, Porsche and Bentley. TFSI is Audi's signature designation for direct-injection petrol turbo engines. On older-generation petrol Audi models, Stage 1 is done via OBD without bench.
APR and Revo are the leading tuning brands for Audi, right up to Stage 1+. Audi S models sit between the standard cars and the RS range. Within the VAG group, ECUs are standardised, so a single file often fits a dozen models across Audi/VW/Skoda/Seat. Audi S models are the milder performance step between the standard cars and the RS range. The premium Audi segment runs a high-output platform with Stage 2 potential. High-output Audi engines sit in the premium segment, with solid headroom for Stage 1.
Tiptronic is Audi's classic automatic for longitudinally mounted engines. S tronic is Audi's signature dual-clutch gearbox (the DSG in the Audi range). S tronic comes in dry and wet-clutch versions, each with a different torque rating.
