About this file
What this Stage 1 file is
This is a Stage 1 tune of the factory calibration of the 1998 Audi A4 1.9 TDI (66.2 kW, 90 hp), for its Bosch EDC15 ECU with hardware 0281001658 and part number 028906021GM. Stage 1 is software only: the car keeps its standard turbo, injectors, intercooler and exhaust.
Stage 1 on this engine raises the injected fuel, the boost and the rail pressure and lifts the torque limiters, within what the standard turbo, injectors and clutch hold. The smoke limiter follows the new airflow, so a healthy engine pulls harder without black smoke.
The file is listed for the 66.2 kW, 90 hp version of the Audi A4 1.9 TDI. Check the power on your car's papers: the same model was sold with several engines, each with its own file.
For this calibration of the Audi A4 1.9 TDI we sell the original and Stage 1, each made from the same original read. Every file downloads straight after payment.
The Bosch EDC15 ECU in this car is read and written over OBD and on the bench, with tools such as Alientech Kess V2, CMD Flash, Dimsport New Genius, MagicMotorsport FLEX, bFlash and Alientech K-Tag. Keep your own read: compare its hardware and software numbers with the ones on this page before you write the file.
DPF off, EGR off, AdBlue (SCR) off, DTC off and speed limiter (Vmax) off can be added to this file on request, for off-road and competition use: send us your read through our file service and our engineers add them (any file £50, from £30 in packs).
Hardware 0281001658 is the number on the Bosch ECU's label. Part number 028906021GM is the car maker's number for this ECU.
