About the Audi A4

About the Audi A4

The Audi A4 is considered a line of luxury compact executive cars produced from 1994 to 2025 by the German car manufacturer Audi, a subsidiary of the Volkswagen Group. The A4 has been built in five generations and is based on the Volkswagen Group B platform. The first generation A4 succeeded the Audi 80. The automaker’s internal numbering treats the A4 as a continuation of the Audi 80 lineage, with the initial A4 designated as the B5-series, followed by the B6, B7, B8, and the B9.

Why Stage 1 for the 1.9 TDI 110hp

Our Stage 1 calibration is designed for a completely stock vehicle — no hardware changes required. In practice this delivers a safe and reversible improvement in drivability.

Typical gains on healthy examples are from around 110 HP to 143 HP and from 240 Nm to 320 Nm (indicative; varies by condition).

What we do

  • Initial diagnostics and a full backup of the original ECU file
  • Calibration of timing/fuelling, torque limiters and boost strategies
  • Throttle response and power delivery refinement with a focus on smoothness
  • Road testing and post-map parameter checks

Safety and Warranty

We follow a conservative approach, maintaining thermal and mechanical margins to protect longevity.

The process is fully reversible (factory file can be restored) and requires no physical modifications.

Summary

A Stage 1 remap turns the Audi A4 1.9 TDI 110hp into a more responsive daily driver while keeping stock-like manners.
