About this calibration file
This is the factory (original) ECU calibration for the Mercedes-Benz E 270 CDI (Turbo Diesel), extracted from a genuine stock control unit. Use it as a verified backup before flashing any performance tune, or as a reference when recovering an ECU from a failed write.
This file matches a Bosch ECU with hardware number CR30-648-C5D4-S211-ME0405-EU4LR130KW-004 and software version 369831. Verify both identifiers in your flashing tool before writing — an ID mismatch is the most common cause of a bricked ECU. If you are unsure, upload a read of your original file via the file-request wizard and our engineers will confirm compatibility before you flash.
The file is delivered as a ready-to-flash BIN (and ORI backup where applicable) compatible with all major tools — KESS V2/V3, KTAG, AutoTuner, CMDFlash, Dimsport New Genius, MPPS, Flex, BFlash, PCMFlash, MMFlash — via OBD, bench or boot-mode as supported by your ECU family. Checksums are pre-computed and verified; no additional checksum tool is required. All files include a free revision if post-flash logs reveal a fuelling, boost or EGT issue.
