Audi A3 1.9 TDI 100hp

Stage 1 chip tuning for the Audi A3 1.9 TDI 100hp increases power from 100 to 142 hp (+42 hp, +42%) and torque from 240 to 320 Nm. Turbocharged diesel engines offer the greatest chip tuning potential – optimizing boost pressure and injection maps delivers significant gains in both power and torque from low RPM.

The remap is performed on the Bosch EDC15P+ ECU (engine code ATD) via the OBD2 diagnostic port – no ECU removal required. We use Alientech KESSv2, Bitbox Bitbox, CMD CMDFlash. Results are verified with a dynamometer measurement.

Under normal driving conditions, chip tuning a turbocharged diesel can reduce fuel consumption – in Eco mode, savings reach up to 0.7 l/100 km thanks to more efficient turbo operation and optimized injection.

In addition to Stage 1, we offer the following services for the Audi A3 1.9 TDI 100hp: EGR valve diagnostics. All work is performed using professional equipment.

If desired, the Audi A3 1.9 TDI 100hp can be upgraded to Stage 2 – a deeper optimization delivering even greater power and torque gains. Stage 2 involves advanced ECU calibration taking into account exhaust system and intercooler modifications. Contact us for a free consultation to evaluate Stage 2 potential for your specific vehicle.

Every vehicle undergoes full diagnostics before and after the remap. We keep a backup of the original ECU calibration and guarantee the option to revert to stock settings at any time. JVK PRO is a professional chip tuning service in Riga with 16 years of experience.
