It’s not detecting the car I was runing firmware 1.9.1.0 I upgrading to 1.9.6.0

If the firmware update didn't fix it, the issue is likely one of three things: Ignition state, Xentry version, or the specific Driver setting.

Here is the checklist to get it talking to the EQE:

1. The "EV Ignition" State
This is the most common mistake on EVs.

The car must be in "Ignition ON" mode, not just "Accessory" mode.
Press the Start button twice without your foot on the brake.
The instrument cluster should light up fully with all the warning lights. If the cluster is dark or only shows the door open, Xentry cannot talk to the Gateway.

2. Update the License in VX Manager
After you update the firmware (to 1.9.6.0), you must update the license on the device, or the diagnostic functions will stay locked.

Open VX Manager.
Click the "Update License" button (usually on the main screen or under the Device tab).
Wait for it to say "License Updated."

3. Check Your Xentry Version
The EQE (W295) is a very new car.

If your Xentry version is older than 09/2022, it does not have the database files for the EQE. It will never detect it.
You need Xentry 2023 or 2024 for proper support of this chassis.

4. Try Manual Selection
If "Auto-Detect" fails, try to force the connection:

In Xentry, choose the "Mercedes-Benz" brand.
Select "Passenger Car".
Look for the "EQE" or "295" chassis code in the list.
Click it and try to connect.

5. The Driver Conflict (C6 vs Passthru)
Double-check which Xentry you have vs. which driver you installed in VX Manager.

If you have Xentry OpenShell (the standard icon), you MUST install the BENZ C6 driver in VX Manager. Uninstall the Passthru driver if it is there.
If you have Xentry Passthru (it says Passthru in the name), you MUST install the PASSTHRU driver in VX Manager.

Note: The "Benz C6" driver handles DoIP (Ethernet) much better for the EQE than the Passthru driver does.

my car said device connected in diagnostics still not reaching

Gemini · 24.02.2026

aj310 said:

That is actually good news. If the car screen says "Diagnostics Connected" (or shows the icon), it means the VCX SE is physically working and has successfully woken up the car's Gateway.

The problem is now purely between the VCX SE and your Laptop. The data is getting to the dongle, but it is not getting into Xentry.

Since this is an EQE (DoIP car), this is almost certainly a Network/IP Configuration issue.

Here is how to fix the link:

1. Check the DoIP Switch
The EQE communicates via Ethernet (DoIP), not the old CAN bus lines.

Open VX Manager.
Go to Device Configuration (or the Settings tab).
Look for a checkbox that says "DoIP" or "DoIP Switch".
Make sure it is CHECKED / ON.
If you change it, click "Save" and restart the device (unplug/replug).

2. Check the Windows Network Adapter
When you plug in the VCX SE, it creates a "Virtual Network Adapter" on your laptop. Xentry uses this to talk to the car.

On your laptop, go to Control Panel -> Network and Sharing Center -> Change Adapter Settings.
Plug in the VCX SE via USB.
You should see a new Local Area Connection appear (often labeled "Realtek USB GbE" or similar).
Right-click it -> Properties -> Internet Protocol Version 4 (TCP/IPv4).
Make sure it is set to "Obtain an IP address automatically" (DHCP).
If it is already automatic and failing, try setting it manually to:
IP:
Code:
```
172.29.127.120
```
Subnet:
Code:
```
255.255.0.0
```

3. Disable the Firewall
Windows Defender Firewall often blocks the DoIP connection because it looks like an "Unidentified Network."

Temporarily turn off ALL firewalls (Domain, Private, and Public).
Try to connect in Xentry again.

4. The "C6" Driver Check
If you are using Xentry OpenShell (XDOS), you must have the BENZ C6 driver installed in VX Manager.

If you installed the "Passthru" driver in VX Manager but you are running Xentry OpenShell, it will wake the car up but fail to read data.
Uninstall "Passthru" in VX Manager and install "BENZ C6".

Summary:
The car sees the tool, so the cable is fine. The issue is that Xentry is looking for data on a network port that is either blocked by a firewall or not configured correctly in Windows.

it says device detected and diagnostic center see operator Manuel

Gemini · 24.02.2026

aj310 said:
it says device detected and diagnostic center see operator Manuel

That message on your dashboard is actually good news.

It confirms that the car detects the VCX SE and has entered "Diagnostic Mode." The physical connection is working. The problem is that the data is stopping at the dongle and not reaching the Xentry software on your laptop.

This is almost always caused by a mismatch between your Xentry Version and the Driver you installed in VX Manager.

You need to match them exactly:

Step 1: Check your Xentry Icon
Look at the Xentry icon on your desktop.

Does it say Xentry Diagnosis (OpenShell) or XDOS?
Or does it say Xentry Passthru?

Step 2: Install the Correct Driver
Open VX Manager, go to the Diagnostic tab, and look at what is installed.

If you have Xentry OpenShell (XDOS):

You MUST install the driver named BENZ C6.
You MUST Uninstall the driver named "Passthru" (if it is installed).
The "Benz C6" driver allows the VCX SE to use the DoIP (Ethernet) protocol required for your EQE.

If you have Xentry Passthru:

You MUST install the driver named PASSTHRU.
You MUST Uninstall the "Benz C6" driver.

Step 3: The DoIP Switch
Since the EQE communicates via Ethernet (DoIP), you must ensure the VCX SE is broadcasting correctly.

Open VX Manager.
Go to Device Configuration (or Settings).
Make sure DoIP is checked/enabled.
If you change it, click Save and unplug/replug the device.

Summary:
The car is waiting for commands (that's why it shows the message). Xentry isn't sending them because it's looking for a "C6" unit but you might have the "Passthru" driver installed (or vice versa). Fix the driver in VX Manager, and Xentry should immediately see the voltage and connect.

I have open shell

Gemini · 24.02.2026

aj310 said:
I have open shell

Since you have Xentry OpenShell, you must configure the VCX SE to "pretend" to be a genuine Mercedes C6 Multiplexer.

Here is the exact fix:

1. The Driver Switch (Critical)
Open VX Manager.
Go to the Diagnostic tab.

UNINSTALL the driver named "PASSTHRU" (if it is installed).
INSTALL the driver named "BENZ C6" (sometimes just labeled "BENZ" or "XENTRY").

*Why?* OpenShell does not listen to "Passthru" drivers by default. It looks for a specific C6 connection. The "BENZ C6" driver creates that emulation.

2. Enable DoIP
Since your EQE requires Ethernet communication:

In VX Manager, go to Device Configuration.
Make sure DoIP is checked/enabled.
Click Save.

3. Do NOT use the Mercedes VCI Manager
Do not try to configure the device using the "ConfigAssist" or "VCI Manager" icons on your desktop. Those are for genuine tools. VX Manager handles everything in the background.

4. Restart and Connect
1. Unplug the VCX SE from the laptop.
2. Restart your laptop.
3. Plug the VCX SE back in.
4. Open Xentry OpenShell.

You should now see the voltage in the top right corner, and it should connect to the car.

Still nothing

If the car sees the device but Xentry does not, the "Bridge" (Driver) between the VCX and Windows is broken.

Here are the 3 most common reasons this happens with Xentry OpenShell + VCX SE:

1. The "VCI Manager" Test
We need to see if the driver is actually loaded.

Close Xentry and VX Manager.
Open the VCI Manager (The Mercedes-Benz icon on your desktop, NOT the VX Manager).
Look at the list on the left.
Do you see a VCI icon there?

Result:

If the list is EMPTY: The "Benz C6" driver from VX Manager did not install correctly. This is often blocked by Windows Security.
If you see the VCI but it has a Red X or says "Disconnect": It is a firewall/IP issue.

2. Secure Boot (BIOS) Blocking the Driver
The VCX SE drivers are not signed by Microsoft. If your laptop has "Secure Boot" enabled in the BIOS, Windows will silently block the driver from loading, even if VX Manager says "Installed."

Restart your laptop and enter BIOS (usually F2 or Del).
Find the "Secure Boot" setting.
Set it to DISABLED.
Save and Exit.

3. The IP Address (Critical for EQE/DoIP)
Since the EQE uses Ethernet, the network settings must be exact.

Plug in the VCX SE.
Go to Control Panel -> Network and Sharing Center -> Change Adapter Settings.
Find the new Network Adapter (it usually says "Realtek USB GbE" or just "Ethernet X").
Right-click -> Properties -> Internet Protocol Version 4 (TCP/IPv4).

Set it to Use the following IP address:

Code:

IP Address: 172.29.127.119
Subnet Mask: 255.255.0.0

Click OK and try Xentry again.

Summary:
If VCI Manager is empty, disable Secure Boot and reinstall the "Benz C6" driver in VX Manager.
If VCI Manager sees it, fix the IP address as shown above.

Yea it say no xentry Vci paired

Gemini · 24.02.2026

aj310 said:
Yea it say no xentry Vci paired

This is the most common confusion with the VCX SE.

You can IGNORE the "No VCI Paired" message in the Mercedes VCI Manager.

The VCX SE is an emulator. It does not "pair" like a genuine $2,000 Mercedes C6 Multiplexer. It will often show as disconnected or empty in the VCI Manager tool, but it will still work inside Xentry if the driver is loaded correctly.

Since Xentry is still not connecting, the issue is that the "Emulator Driver" is being blocked by Windows.

Here is the fix:

1. Disable Secure Boot (Crucial)
The VCX SE driver is not signed by Microsoft. If your laptop has "Secure Boot" enabled in the BIOS, Windows will silently block the driver, even if VX Manager says "Installed."

Restart your laptop and enter BIOS (F2, F10, or Del).
Find "Secure Boot" and set it to DISABLED.
Save and Exit.

2. Clean Reinstall of the Driver
Once Secure Boot is off, you must reload the driver files:

Open VX Manager -> Diagnostic Tab.
Uninstall the "BENZ C6" driver.
Restart the Laptop.
Open VX Manager -> Diagnostic Tab -> Install "BENZ C6" driver again.

3. Verify the "Virtual" Connection
Do not look at VCI Manager. Look at your Windows Taskbar (bottom right, near the clock).

Do you see a small icon that looks like a grey or white pyramid (VX Manager Agent)?
If not, open VX Manager and keep it open in the background.

4. The Final Test

Connect the VCX SE to the car (Ignition ON).
Connect the USB to the laptop.
Open Xentry OpenShell.

If the voltage (top right) still shows 0.0V or empty, close Xentry and try this specific IP setting for the EQE:

Manual IP Configuration (For DoIP/Ethernet):

Go to Control Panel -> Network Connections.
Find the "Realtek USB GbE" adapter (or the one created by the VCX).
Right-click -> Properties -> IPv4.

Set to Manual IP:

Code:

IP Address: 172.29.127.119
Subnet Mask: 255.255.0.0

Click OK and try Xentry again.

Finally got it work where exactly should I go to turn the charging back on can you check these pics tell me what I should do ac charger and dc charging inoperative

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 bypass 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 bypass the Xentry security checks.

Type of drive ?

Yes, you want to select the Drive category (sometimes labeled as Drive System or Antrieb).

In the EQE (W295), the High Voltage and Charging systems are grouped under Drive.

Here are the specific Control Units you need to check inside that menu:

N82/2 - Battery Management System (BMS)
- This is the most important one. It controls the main contactors (relays) inside the battery.
- If this module has a "Crash Detected" or "Insulation Fault" code, it disables all charging.
N24/3 - Charger (OBC)
- This is the On-Board Charger for AC charging.
- Check this if your AC charging is failing but the car still drives.
N127 - Electric Drivetrain (eATS)
- This is the main powertrain controller. It often stores the "Interlock" status (the safety loop).

What to do:
1. Go to Control Units -> Drive.
2. Enter N82/2 (BMS) first.
3. Go to the Fault Codes tab.
4. If you see a code like "The high-voltage on-board electrical system is deactivated due to a crash", go to the Special Procedures (or Adaptations) tab and look for "Unlock High Voltage System".

My car lost charging because of a small accident and airbags deployed everything is good as far as structure just car won’t charge anymore

Gemini · 24.02.2026

aj310 said:

Since the airbags deployed, this is almost certainly a hardware issue first, and a software issue second.

In the EQE (W295), when the airbag control unit triggers, it sends a signal to the Pyrofuse (Pyrotechnic Separator) to physically explode and cut the High Voltage (HV) line to prevent a fire.

You cannot fix this with software alone.

Here is the step-by-step repair procedure for a crash-locked EQE:

1. The Pyrofuse (Hardware Check)
If the airbags went off, the Pyrofuse is 99% likely blown.

This fuse is located in the F32 or F33 Pre-Fuse Box (usually near the 12V battery or under the cowl).
You must check it for continuity with a multimeter (with the HV system disabled/safe).
If it is open (blown), you must replace the entire fuse block.
Symptom: If you try to clear codes in Xentry, they will immediately return as "Open Circuit" or "Interlock Loop Open."

2. The Software Unlock (BMS Reset)
Once the physical fuse is replaced, the Battery Management System (BMS) will still be "Locked" because it remembers the crash.

You must perform the "Unlock High-Voltage System" routine.

In Xentry:

Go to Control Units -> Drive -> N82/2 (BMS).
Select Adaptations (or Special Procedures).
Look for Teach-in processes or Commissioning.
Select "Unlock high-voltage on-board electrical system after crash".

3. If Xentry Fails (ZenZefi Security)
The EQE (W295) is protected by the new Mercedes security architecture (ZenZefi).
If Xentry asks for a "Certificate" or "User Login" when you try to unlock the BMS, you cannot proceed with offline Xentry.

In that case, you must use DTS Monaco to force the reset:

Code:

ECU: BMS_GEN5 (or similar for EQE)
Service: RoutineControl
Routine: "Unlock_HV_System" or "Reset_Crash_Data"

Summary:
Do not waste time trying to code it yet. Check the Pyrofuse first. If that fuse is blown, the car will never charge, no matter what you do in the software.

I changed both purpose drove the car just car never charged back up

Gemini · 24.02.2026

aj310 said:
I changed both purpose drove the car just car never charged back up

That is a very specific situation. If the car drives but does not charge, it means the main High Voltage contactors are working (so the Pyrofuse is definitely good), but the Charging Logic is still locked in "Safety Mode."

The BMS (Battery Management System) allows discharging (driving) to get you to a shop, but it disables charging (AC and DC) to prevent a fire risk while the car is unattended.

You need to clear the Crash Signal specifically from the Charging Modules.

Here is exactly where to look in Xentry:

Step 1: Unlock the BMS (N82/2)
Even though you can drive, the BMS still holds a "Crash Detected" flag that blocks the charger.

Go to Control Units -> Drive -> N82/2 Battery Management System.
Select the Adaptations (or Special Procedures) tab.
Look for a line that says: "Enable charging" or "Reset crash signal".
Run that procedure.

Step 2: Unlock the On-Board Charger (N24/3)
The AC Charger module often locks itself independently during a crash.

Go back to Control Units -> Drive.
Select N24/3 (OBC / Charger).
Check Fault Codes first. If you see "Crash signal received," it is locked.
Go to Adaptations or Teach-in processes.
Look for "Resetting of crash data" or "Unlock component".

Step 3: The 12V Battery Check
This is critical for the EQE. If the car sat for a while after the accident, the 12V battery might be weak.

If the 12V battery is below a certain voltage, the BMS will refuse to close the charging contactors.
Check the voltage in the top right of Xentry. If it is below 12.5V, connect a strong external power supply (charger) to the 12V jump points under the hood while you try to unlock it.

If Xentry Asks for a Certificate (ZenZefi):
Since this is a W295 (EQE), Xentry might block these resets and ask for an online login. If that happens, you cannot do it with Xentry OpenShell. You will have to use DTS Monaco to send the "Hard Reset" command directly to the ECU.

Let me know if Xentry lets you run the "Enable Charging" routine or if it pops up a login window.

How would I do it in dts

Gemini · 24.02.2026

aj310 said:

Using DTS Monaco is the correct approach if Xentry is blocked by security certificates, but be very careful. DTS Monaco is an engineering tool—it has no safety checks and does not ask "Are you sure?".

Here is the procedure to unlock the High Voltage (HV) system on the EQE (W295) using DTS Monaco.

Prerequisites

You must have the correct SMR-D file for the EQE Battery Management System (usually named BMS_GEN5.smr-d or similar).
Your VCX SE must be connected and recognized in DTS Monaco.

Step 1: Connect to the ECU
1. Open DTS Monaco.
2. Create a new Workspace (or use "Temporary Workspace").
3. Add the SMR-D file for the BMS (Battery Management System).
* Look for: BMS_GEN5 (most common for EQE/EQS) or SG_BMS.
4. Start the workspace and ensure the ECU is "Reachable" (Green indicator).

Step 2: Unlock Security (Seed & Key)
You cannot reset crash data without unlocking the ECU's security level first.
1. Go to the Diagnostic Services tab.
2. Find the group Security Access.
3. You need to unlock a high security level. For HV systems, it is usually:
* Level 37 (Safety / Crash)
* OR Level 67
* OR Level 0B (Development)
4. Select the level and click Unlock (or Request Seed -> Send Key).
* Note: If you get a "Negative Response", your DTS installation might lack the specific Seed/Key DLLs for the W295 chassis.

Step 3: Run the Reset Routine
Once unlосkеd, you need to send the command to clear the crash lock.
1. Go to the Routine Control tab (sometimes inside Diagnostic Services).
2. Search for a routine with one of these names (exact names vary by SMR file version):

Code:

Routine_Unlock_HV_System
Routine_Reset_Crash_Data
Routine_Enable_Charging
Routine_Clear_Lock_Status

3. Select the routine and click Start (or Execute).
4. Look at the bottom log. You MUST see a Positive Response (usually green text).

Step 4: Hard Reset and Clear Codes
After the routine finishes:
1. Go to ECU Reset.
2. Select Hard Reset (11 01) and execute it.
3. Wait 10 seconds.
4. Go to Clear DTC and execute it to wipe the fault codes.

Final Check:
Disconnect the laptop, lock the car, wait 15 minutes (bus sleep), then unlock and try to charge. If the Pyrofuse is good and the routine passed, it will charge.
