Audi A6 2.5 TDI 180hp Remap

The Audi A6 2.5 TDI 180hp is a 2.5L turbocharged diesel engine producing 180 BHP and 370 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 210 BHP and 420 Nm — a gain of around 30 BHP (17%) and 50 Nm (14%).

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 typically a Bosch EDC15 (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..

Considerations: High tuned torque: check transmission torque capacity and service history.. Older diesel: injector, turbo and intake condition can affect results; ensure maintenance is up to date.

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.
