  • Your own read saved twice, on two different drives: it is your way back.
  • Your read shows hardware 0261201541, part number 03C906032C and software 396313 (1037396313), the same as this file.

About this file

What this original file is

This is the factory calibration of the 2002 VW Touran 1.4 TSI (103 kW, 140 hp), for its Bosch MED17.5.1 ECU with hardware 0261201541, part number 03C906032C and software 396313 (1037396313). Use it to put the car back to standard, to recover the ECU after a failed write, or as the base of a tune of your own.

An original holds every map as the factory wrote them: ignition, fuelling, boost and the torque limits, the speed limiter and the emissions controls. Tuners start a file from it; workshops use it to put a car back to standard.

The file is listed for the 103 kW, 140 hp version of the VW Touran 1.4 TSI. Check the power on your car's papers: the same model was sold with several engines, each with its own file.

For software 396313 of the VW Touran 1.4 TSI we sell the original and Stage 1. Stage 1 comes in two versions, tuned from different reads of this software. Every file downloads straight after payment.

The Bosch MED17.5.1 ECU in this car is read and written over OBD, on the bench and in boot mode, with tools such as Alientech KESS3, Alientech K-Tag, Autotuner, MagicMotorsport FLEX, CMD Flash and CMD. 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 built on 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 0261201541 is the number on the Bosch ECU's label. Software 396313 (1037396313) is the calibration inside it: a read with hardware 0261201541 and another software number needs a different file. Part number 03C906032C is the car maker's number for this ECU.

Questions

Which ECU does this VW Touran 1.4 TSI original file fit?

A Bosch MED17.5.1 ECU with hardware 0261201541, part number 03C906032C and software 396313 (1037396313). Check those numbers in your read before you write it; another software number needs another file, which our engineers can build from your read.

How is the Bosch MED17.5.1 read and written?

Over OBD, on the bench and in boot mode, with tools such as Alientech KESS3, Alientech K-Tag, Autotuner, MagicMotorsport FLEX and CMD Flash. Write the file back the same way you read the ECU, and keep your original read.

Can you add catalyst off to the Bosch MED17.5.1 file?

Yes, on request, for off-road and competition use: catalyst off, DTC off and speed limiter (Vmax) off. Upload a read through our file service and an engineer builds it (any file £50, from £30 in packs). The buyer is responsible for using it where the law allows.

What exactly is in the download?

A BIN file of 256 KB, ready to write. Write it with the same tool and the same connection you read the ECU with.

How do I get the file after paying?

It is in your account as an instant download straight after payment by card, Apple Pay or Google Pay: the BIN file, ready to write.

What if the file does not fit my car?

Send us your read and we correct it free, as many times as it takes. Questions before you buy are answered by a tuner on WhatsApp.
