Audi A4 40 TDI (2.0D) 190hp Remap

The Audi A4 40 TDI (2.0D) 190hp is a 2.0L turbocharged diesel engine producing 190 BHP and 400 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 220 BHP and 450 Nm — a gain of around 30 BHP (16%) and 50 Nm (12%).

This engine has moderate remap suitability, with a balanced spread of gains across both power and torque — providing a noticeable improvement across the rev range. The tuning headroom is classified as moderate, based on the percentage gain available from the factory output.

From a technical perspective, the ECU is a Bosch EDC17 (likely), and the transmission is manual and dsg/s tronic automatics are common depending on model/engine. some dsg/dual-clutch gearboxes have torque management; calibration may be torque-limited. at this torque level, transmission and driveline servicing history becomes especially important..

Considerations: High tuned torque: check transmission torque capacity and service history.

Fuel economy note: possible improvement with conservative driving.

All figures shown are typical estimates based on aggregated Stage 1 data for this engine variant. Actual results depend on vehicle condition, mileage, and the chosen tuning method. We recommend discussing your specific vehicle with a qualified remap professional.
