About this file
What this original file is
This is the factory calibration of the 1999 VW Golf 1.8 T (110 kW, 150 hp), for its Bosch ECU with hardware 0261204673, part number 06A906018R and software 359551 (1037359551). 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 Golf 1.8 T carries the 1.8T engine, 150 hp and 210 Nm from the factory. On this engine, Stage 1 usually gives about 195 hp and 290 Nm (+45 hp, +80 Nm). Typical figures for a healthy engine: your car's own result depends on its condition, fuel and parts.
For software 359551 of the VW Golf 1.8 T we sell the original and Stage 1, each made from the same original read. Every file downloads straight after payment.
The Bosch ECU in this car is read and written over OBD and on the bench, with tools such as Alientech KESS3, Alientech K-Tag, MagicMotorsport FLEX, CMD Flash, Dimsport NewGenius 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, speed limiter (Vmax) off, pops and bangs and anti-lag 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 0261204673 is the number on the Bosch ECU's label. Software 359551 (1037359551) is the calibration inside it: a read with hardware 0261204673 and another software number needs a different file. Part number 06A906018R is the car maker's number for this ECU.
Questions
Which ECU does this VW Golf 1.8 T original file fit?
A Bosch ECU with hardware 0261204673, part number 06A906018R and software 359551 (1037359551). 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 ECU read and written?
Over OBD and on the bench, with tools such as Alientech KESS3, Alientech K-Tag, MagicMotorsport FLEX, CMD Flash and Dimsport NewGenius. Write the file back the same way you read the ECU, and keep your original read.
What does Stage 1 give on the VW Golf 1.8 T?
Usually about 195 hp and 290 Nm against 150 hp and 210 Nm stock (+45 hp, +80 Nm). Typical for a healthy engine, never a promise for one car.
Can you add catalyst off to the Bosch ECU file?
Yes, on request, for off-road and competition use: catalyst off, DTC off, speed limiter (Vmax) off, pops and bangs and anti-lag. 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.

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?
