About this file
What this original file is
This is the factory calibration of the 2008 VW Golf5 1.4 TSI (103 kW, 140 hp), for its Bosch MED17.5.1 ECU with hardware 0261201355, part number 03C906032 and software 387599 (1037387599). 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 VW Golf5 1.4 TSI carries the 1.4 TSI (BMY) engine, 140 hp and 220 Nm from the factory. On this engine, Stage 1 usually gives about 200 hp and 300 Nm (+60 hp, +80 Nm); Stage 2 usually gives about 220 hp and 330 Nm (+80 hp, +110 Nm). Typical figures for a healthy engine: your car's own result depends on its condition, fuel and parts.
For software 387599 of the VW Golf5 1.4 TSI we sell the original, Stage 1 and Stage 2, each made from the same original read. Every file downloads straight after payment.
The Bosch MED17.5.1 ECU in this car is read and written over OBD and on the bench, with tools such as Alientech Kess V2, Autotuner, CMD Flash, Dimsport New Trasdata, MagicMotorsport FLEX 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.
The same 1.4 TSI (BMY) engine with the same ECU is fitted to the Volkswagen Touran I: their file can be the same, so check the software number of your read.
Catalyst off, DTC off, speed limiter (Vmax) off, swirl flaps off, start/stop off and pops and bangs 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 0261201355 is the number on the Bosch ECU's label. Software 387599 (1037387599) is the calibration inside it: a read with hardware 0261201355 and another software number needs a different file. Part number 03C906032 is the car maker's number for this ECU.
How the Bosch MED17.5.1 is read and written

Questions
Which ECU does this VW Golf5 1.4 TSI original file fit?
A Bosch MED17.5.1 ECU with hardware 0261201355, part number 03C906032 and software 387599 (1037387599). 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 and on the bench, with tools such as Alientech Kess V2, Autotuner, CMD Flash, Dimsport New Trasdata and MagicMotorsport FLEX. Write the file back the same way you read the ECU, and keep your original read.
What does Stage 1 give on the VW Golf5 1.4 TSI?
Usually about 200 hp and 300 Nm against 140 hp and 220 Nm stock (+60 hp, +80 Nm). Typical for a healthy engine, never a promise for one car.
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, speed limiter (Vmax) off, swirl flaps off, start/stop off and pops and bangs. 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.
Stage 1 or Stage 2 on the VW Golf5 1.4 TSI?
Stage 1, about 200 hp and 300 Nm, is for a standard car. Stage 2, about 220 hp and 330 Nm, is written for a car with supporting parts: a freer exhaust, a bigger intercooler and a clutch that holds the torque, as this engine needs.
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?
