Description

MB CLS original ECU flash file (not a backup) Bosch ME9.7 hardware 0261209040 software 6K09060O300
MB CLS — original stock flash file for this ECU, not a full backup.

Download the original ECU flash file for the MB CLS 350i 272hp running Bosch ME9.7. This listing is stock flash / calibration data only — not a full ECU backup, not a processor clone, and not an immobilizer EEPROM.

Match hardware 0261209040 and software 6K09060O300 before you write. A neighbouring software version on the same CLS can still fail the checksum or leave a no-start.

Use this OEM flash to restore factory calibration after a bad remap, to compare a modified dump, or to prepare a professional write. Hardware 0261209040 with software 6K09060O300 is a different package from other MB original files on this site.

What this MB CLS original file is

It is the stock map for professional tuners and ECU repair shops. If you need a complete ECU image for cloning or brick recovery, that is a full backup — sold separately on request for €20. ECU flash repair after a failed write is €50.

Full backups and ECU flash repairs

  • Full ECU backup (complete image for clone or recovery): €20 on request — this original listing is a flash / calibration file only — it is not a full backup.
  • ECU flash repair after a failed write or brick: €50 — contact support with HW/SW and the tool you use.

Professional use only

These files are intended for professional tuners, ECU specialists and workshops. You must understand flashing, checksums, boot/bench recovery and the risk of a no-start. We do not sell this as a DIY kit for untrained use.

Digital product — no refund after payment

This is a digital file delivered after payment. Once it is paid we cannot refund, reverse or take back the download. Check hardware and software numbers on the ECU sticker before you buy.
