Chip tuning for Audi S4 3.0 TDI EU6 347 hp ECU
Audi S4 (2019 - B9-FL) 3.0 TDI EU6 347 hp — premium diesel engine of the passenger segment of the Volkswagen Group (VAG) group (Германия, 1909). Stage 1 chip tuning raises power from 347 to 390 hp (+43 hp, +12%) and torque from 700 to 780 Nm (+80 Nm). ECU — Bosch MD1CP004. Flashing method: OBD or Bench depending on the unit's protection. The ZF AL552 TCU is calibrated with a separate file — torque limiter and shift maps for Stage 1. In the CHIPOK database: 2 configurations · 2 ECU variants. A modern diesel built in 2019 — a generation with encrypted firmware (Tricore TPROT) that often requires a Bench read.
Audi is part of the Volkswagen Group (VAG), Europe's largest automotive group. Audi Sport is Audi's performance division, building the RS models. Audi shares platforms with Volkswagen, Porsche, Bentley and Lamborghini within VAG. 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. The MQB platform lets a single calibration cover Audi/VW/Skoda/Seat.
Audi S models sit between the standard cars and the RS range. On the Audi Q-series diesel SUVs, Stage 1 focuses on torque. The Audi community is renowned for its active tuning scene and a huge library of available Stage files. 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. Audi S models are the milder performance step between the standard cars and the RS range.
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. The S tronic TCU requires calibration at Stage 1+, as the torque limiter usually sits below the engine's potential.

How much does the power of the Audi S4 3.0 TDI EU6 347 hp increase after Stage 1?
After Stage 1 the power of the Audi S4 3.0 TDI EU6 347 hp rises from 347 to 390 hp, a gain of 43 hp (+12%). Torque rises from 700 to 780 Nm (+80 Nm).
How does Stage 1 differ from stock on the Audi S4?
Stage 1 on the Audi S4 3.0 TDI EU6 347 hp is a software ECU calibration with no hardware changes. The key maps (boost/ignition/lambda/torque) are adjusted while factory tolerances are preserved. The gain is +43 hp with no hardware changes.
What does Stage 1 give on the powerful Audi S4 3.0 TDI EU6 347 hp?
The high-output Audi S4 3.0 TDI EU6 347 hp has a conservative factory calibration aimed at the mass market. Stage 1 unlocks the engine's real potential while turbo and injector life are preserved.
How does Stage 2 differ from Stage 1 on the Audi S4 3.0 TDI EU6 347 hp?
Stage 2 on the Audi S4 3.0 TDI EU6 347 hp means software + hardware (exhaust, intake, intercooler). The gain depends on the specific hardware combination.
What control unit does the Audi S4 3.0 TDI EU6 347 hp run?
The control unit of the Audi S4 3.0 TDI EU6 347 hp is the Bosch MD1CP004. Before flashing, the engineer identifies the exact revision and selects the write method.
Does the ZF AL552 transmission need calibration after Stage 1 on the Audi S4?
Remapping the ZF AL552 gearbox is essential to fully unlock Stage 1 on the Audi S4 3.0 TDI EU6 347 hp. Without a TCU update the factory torque cap will choke the torque gain and shifts will become noticeably softer.
Does Stage 1 void the warranty on the Audi S4?
Stage 1 on the Audi S4 voids the factory warranty on the engine and transmission — this is standard for all manufacturers. CHIPOK provides its own warranty on the quality of the remap.
How quickly is chip tuning of the Audi S4 3.0 TDI EU6 347 hp done?
The full remap cycle for the Audi S4 — from reading to writing the final file — takes 30-90 minutes depending on the ECU access method. The file is prepared at CHIPOK in 5-30 minutes.
Can you return to stock after Stage 1 on the Audi S4?
The original Audi S4 ECU is always saved before flashing. Rolling back to the factory firmware is done with the same programmer in 25-30 minutes.
How much does Stage 1 cost for the Audi S4 3.0 TDI EU6 347 hp?
The cost of Stage 1 for the Audi S4 3.0 TDI EU6 347 hp is calculated in the calculator on this page — you select the options (DPF off, EGR off, AdBlue off, DTC off, etc.) and the price is capped by the package Max Price. Payment is by credits (1 cr = 1 €), with no subscriptions.
