Finally got it work where exactly should I go to turn the charging back on can you check these pics ...
Great job getting the connection working. Since you cannot upload images directly here, I will guide you based on the standard procedure for the EQE (W295) when it shows "Charging Inoperative."
This error usually means the
BMS (Battery Management System) has locked the High Voltage system for safety, often due to a crash signal, insulation fault, or a detected surge.
Here is the exact path in Xentry to reset it:
Step 1: Go to the BMS ECU
1. Run a
Quick Test (let it scan all modules).
2. On the left menu, go to
Control Units.
3. Select
Drive.
4. Look for
N82/2 - Battery Management System (BMS) (sometimes labeled as
SG-BMS).
5. Double-click to enter it.
Step 2: Check the Fault Codes
Before you try to unlock it, look at the
Fault Codes tab.
- If you see a code like "Crash signal detected" or "Interlock loop open", it is a safety lock.
- If you see "Insulation resistance too low", do NOT force the system on. You have a physical short circuit (dangerous).
Step 3: The Unlock Procedure
If the fault is just a "Crash Data" lock or "Contactor Open" lock, follow this path:
1. Click on the
Adaptations (or sometimes
Special Procedures) tab at the top.
2. Look for a menu item named:
*
Unlock high-voltage on-board electrical system
* OR
Resetting of crash data
* OR
Enable charging
3. Select it and follow the on-screen instructions.
*
Note: You usually need the Ignition ON and the Engine OFF.
Step 4: Check the Pyrofuse
If Xentry says "Procedure Successful" but the charging is still inoperative, or if the fault code says "Open Circuit" in the HV path:
- The Pyrofuse (Pyrotechnical Separator) inside the pre-fuse box might be blown.
- On the EQE, this is a physical fuse that explodes to cut power during a crash. If it is blown, no amount of software coding will fix it; it must be replaced.
Important Note on ZenZefi (Security)
The EQE is a very new car (Gen 2023+ architecture).
- If Xentry asks for a Certificate, User Login, or says "Access Denied" when you try to run the unlock function, it means the car is protected by Mercedes' new ZenZefi security cloud.
- Offline Xentry (which you are likely using with the VCX SE) often cannot bураss this block on 2023+ models without a specific "Offline Certificate" installed.
If you get a "Certificate" error, let us know. You might need to use DTS Monaco (which you asked about earlier) to force the unlock, as it can sometimes bураss the Xentry security checks.
