Siemens MS41 original ECU files

Questions

Are these files modified?

No. Every file is an original (stock) read of a Siemens MS41 control unit, delivered exactly as read. If you need a modified file, order tuning below.

How do I find the right file?

Read the ECU with your tool and compare the hardware (HW) and software (SW) numbers — and the calibration when several files share one software number. The vehicle name alone is not enough: the identifiers decide.

How do I get the file?

Register on our file service fs.auto-remap.com, top up your balance and download the file straight away. Every original file costs €20.

What exactly do I receive?

The original read only, as a ZIP archive with an .ori file inside — rename it to .bin if your tool expects that. No full backups, EPROMs, SGO, VBF or other formats. Different tools expect different file sizes when writing, so make sure the file suits your device. All sales are final: check HW and SW against your own read before you buy.

My number is not listed. What now?

Send us the HW/SW numbers of your ECU on WhatsApp or by email. We check our full archive and reply.

Can you tune Siemens MS41?

Yes. We make Stage 1/2 files and DPF, EGR, AdBlue/SCR and DTC solutions for Siemens MS41 (depending on the engine). Upload your read on our file service.
