For a 2023 EQE (W295), the files you need are likely already on your laptop IF you have a recent version of Xentry (e.g., 09/2023 or newer).

However, it is important to distinguish between the two types of files:

1. Diagnostic Files (SMR-D) - YOU NEED THIS
To clear the crash codes (P2E3262 / P1C8000) and unlock the charger, you need the SMR-D file to load into DTS Monaco. You do not need to flash the unit.

Check this folder on your drive:
C:\ProgramData\Mercedes-Benz\Xentry\Kontexte\ODXProjekte\PKW_COMMON\dbr
(Sometimes it is in C:\Program Files (x86)\Mercedes-Benz\Xentry\Kontexte\ODXProjekte\PKW_COMMON\dbr)

Look for these specific files for the W295:
  • Charger (OBC): OBC223.smr-d (The EQE shares the charger with the W223 S-Class).
  • Battery (BMS): BMS_GEN5.smr-d or SG_BMS.smr-d.

2. Flash Files (SMR-F) - YOU LIKELY DO NOT NEED THIS
If you are trying to "Flash" the module to fix the crash code, it will not work. The crash status is stored in the memory (EEPROM), not the firmware. Flashing a locked module will usually fail or leave the code active.

If you still need the flash files for a 2023 model, they are stored here:
C:\ProgramData\Mercedes-Benz\Xentry\Flash
C:\Program Files (x86)\Mercedes-Benz\SDFlash\Release

If the files are missing:
Since the car is a 2023 model, if your Xentry version is older (e.g., 2021 or 2022), you will not have these files. You must download a newer SDFlash database or install Xentry 12/2023 or 03/2024.

Critical Warning for 2023 EQE:
The W295 uses ZenZefi certificates for security. Even if you have the files, DTS Monaco might give you a "Security Access Denied" or "Negative Response" when you try to unlock the crash data because you don't have the online certificate.
  • If you get "Access Denied" on Security Level 37, you will need a Seed/Key Calculator specifically for the W295/W223 architecture, or a paid remote coding service to unlock it.
