About this file
What this Stage 2 file is
This is a Stage 2 tune of the factory calibration of the 2005 Audi A3 2.0 TFSI (147 kW, 200 hp), for its Bosch MED91 ECU with hardware 0261B00486 and part number 8P0907115. Stage 2 is written for a car with supporting parts fitted; if yours differ from the usual build, we match the file to them.
Stage 2 on this engine goes further than Stage 1 and expects supporting parts: a freer exhaust or downpipe, a bigger intercooler and a clutch rated for the torque. Fit them first; on a standard car a Stage 2 file asks more than the parts give.
The file is listed for the 147 kW, 200 hp version of the Audi A3 2.0 TFSI. 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 A3 2.0 TFSI we sell the original, Stage 1 and Stage 2, each made from the same original read. Every file downloads straight after payment.
The Bosch MED91 ECU in this car is read and written over OBD and on the bench, with tools such as Alientech KESS3, Alientech K-Tag, Autotuner, MagicMotorsport FLEX, CMD Flash and Dimsport New Genius. Keep your own read: compare its hardware and software numbers with the ones on this page before you write the file.
Catalyst 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 0261B00486 is the number on the Bosch ECU's label. Part number 8P0907115 is the car maker's number for this ECU.
