Questions

Are these files modified?

No. Every file is an original (stock) read of a 12657305 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?

Open the file page and use Quick buy: €20 by card, no registration. We request the file from the original-file database and e-mail it to you — usually within minutes, normally within 24 hours. With an account on our file service fs.auto-remap.com you can also top up your balance and order there.

What exactly do I receive?

The original read only, as a ready-to-use .bin file (ordered through a file-service account: a ZIP archive with an .ori file inside). 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?

Then we do not have this file: every original file we have is listed on this site and found by its search, so we cannot get it for you. Search one number at a time — HW, SW or calibration — exactly as it appears in your read.

Can you tune 12657305?

Yes. We make Stage 1/2 files and DPF, EGR, AdBlue/SCR and DTC solutions for 12657305 (depending on the engine). Upload your read on our file service.
