About this file
What this original file is
This is the factory calibration of the 2001 MB S 320 CDI (145 kW, 197 hp), for its Bosch ECU with hardware 0281010828 and software 351690 (1037351690). 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: injection quantity and timing, boost and rail pressure, the torque and smoke limiters, the speed limiter and the emissions controls. Tuners start a file from it; workshops use it to put a car back to standard.
The MB S 320 CDI carries the 320 CDI engine, 197 hp and 470 Nm from the factory. On this engine, Stage 1 usually gives about 232 hp and 550 Nm (+35 hp, +80 Nm). Typical figures for a healthy engine: your car's own result depends on its condition, fuel and parts.
For software 351690 of the MB S 320 CDI we sell the original, Stage 1, Stage 2 and Stage 3, 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 CMD Flash and Alientech Kess V2. Keep your own read: compare its hardware and software numbers with the ones on this page before you write the file.
EGR 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 0281010828 is the number on the Bosch ECU's label. Software 351690 (1037351690) is the calibration inside it: a read with hardware 0281010828 and another software number needs a different file.
Questions
Which ECU does this MB S 320 CDI original file fit?
A Bosch ECU with hardware 0281010828 and software 351690 (1037351690). 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 CMD Flash and Alientech Kess V2. Write the file back the same way you read the ECU, and keep your original read.
What does Stage 1 give on the MB S 320 CDI?
Usually about 232 hp and 550 Nm against 197 hp and 470 Nm stock (+35 hp, +80 Nm). Typical for a healthy engine, never a promise for one car.
Can you add EGR off to the Bosch ECU file?
Yes, on request, for off-road and competition use: EGR 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 1 MB, 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?
