none one the whole I downloaded xentry with a ssd would the programs be on that
Click to expand...

Yes, that is exactly where they are. If you installed Xentry on a separate SSD, all the database files are on that SSD, not on your C: drive.

Here is what to do:

Step 1: Find the SSD Drive Letter
1. Open File Explorer.
2. Look on the left side under "This PC".
3. You will see your drives listed. Your SSD will be a different letter like D: or E: or F:.
4. Note the letter.

Step 2: Search the SSD
1. Click on that SSD drive (for example D:).
2. In the search bar at the top right, type:
Code: 
*.smr-d
3. Let it search. This will take a few minutes.
4. If it finds hundreds of files, that is your database. Note the folder path.

Step 3: Manual Navigation on the SSD
If the search is slow, try navigating manually. Look for these paths on your SSD:

Code: 
D:\ProgramData\Mercedes-Benz\Xentry\Kontexte\ODXProjekte\PKW_COMMON\dbr

or

Code: 
D:\Mercedes-Benz\Xentry\Kontexte\ODXProjekte\PKW_COMMON\dbr

or

Code: 
D:\Xentry\Kontexte\ODXProjekte\

Replace D: with whatever letter your SSD is.

Step 4: Once You Find Them
1. Find OBC223.smr-d and BMS_GEN5.smr-d.
2. Copy both files to your Desktop on your main drive.
3. Now when you set up the project in DTS Monaco System Configuration, point the import to your Desktop where you copied them.

Important:
Some Xentry SSD installations are designed to boot from the SSD as a standalone system. If that is the case, the folder structure might look completely different. Look for any folder called ODXProjekte or dbr anywhere on that SSD. That is where the SMR-D files live.

Is that prolly why my crash data ain’t clear ?
Click to expand...

Yes, 100% that is why.

Without the SMR-D files, DTS Monaco has absolutely nothing to work with. It is like trying to make a phone call with no SIM card. The software opens but it cannot:

  • Talk to the ECUs
  • Know what routines are available
  • Know what security access levels exist
  • Know what fault codes mean
  • Send any commands to the car

So even if you were clicking buttons and it looked like something was happening, Monaco was running in simulation mode the whole time. It was not actually communicating with your car at all.

Here is your fix:

1. Plug in that Xentry SSD.
2. Find the SMR-D files on it.
3. Copy them to your main laptop.
4. Set up the project in Monaco properly using those real files.
5. Make sure your interface is set to VCX and NOT simulation.
6. Then follow the step-by-step guide I gave you earlier.

Once Monaco has the correct SMR-D files loaded and is actually talking to the car through the VCX, the crash reset routine will actually execute on the real ECU and clear the crash flag for real.

Everything you did before was basically Monaco talking to itself. Nothing was sent to the car.

So I could of probably cleared my codes from xentry
Click to expand...

Yes, you could have cleared the basic fault codes from Xentry, but there is a big difference:

What Xentry CAN do:
  • Read fault codes
  • Clear fault codes
  • Basic diagnostics
  • Guided tests

What Xentry CANNOT do:
  • Clear the crash flag itself
  • Run the Crash Reset Routine
  • Unlock Security Access Level 37

Here is the problem:

Even if you clear the codes in Xentry, the crash flag is still stored deep inside the ECU. The codes will come right back within seconds because the flag is still set. It is like wiping a warning light off your dashboard but the actual problem is still there telling the light to come back on.

Think of it like this:

  • Fault codes = the symptom (the warning light)
  • Crash flag = the actual cause (the lock inside the ECU)

Xentry can wipe the symptom but cannot remove the cause. Only DTS Monaco (or a dealer-level tool with engineering access) can run the specific routine that resets the crash flag inside the OBC and BMS.

So your game plan is:

1. Plug in your Xentry SSD.
2. Find the SMR-D files.
3. Copy them to your laptop.
4. Load them into DTS Monaco.
5. Connect to the car for real through the VCX.
6. Unlock security access.
7. Run the crash reset routine.
8. THEN clear the codes.

That is the only way the codes stay gone and the charger starts working again.

will xentry know I have my ssd plugged inn
Click to expand...

It depends on how your Xentry SSD was set up. There are two types:

Type 1: Bootable Xentry SSD
This is the most common type people download. It is designed to boot your whole computer from the SSD like a separate operating system.

How to use it:
1. Plug the SSD into your laptop.
2. Turn OFF your laptop completely.
3. Turn it back ON.
4. Immediately start pressing F12 or F2 or ESC (depends on your laptop brand) to open the Boot Menu.
5. Select the SSD from the boot list.
6. Your laptop will boot into a completely separate Windows installation with Xentry already set up and ready to go.
7. Xentry will open and everything is pre-configured.

If this is your type, you cannot just plug it in while your normal Windows is running and expect it to work. It is a whole separate system.

Type 2: Installed Xentry on a Regular SSD
This means someone installed Xentry like a normal program but put it on a second drive. In this case you can just plug it in and access the files normally through File Explorer.

How to Tell Which One You Have:
1. Plug the SSD into your laptop while Windows is running.
2. Open File Explorer.
3. Click on the SSD drive.
4. If you see normal folders like Program Files, ProgramData, Windows, Users = It is a bootable SSD. You need to boot from it.
5. If you see Mercedes-Benz or Xentry folders directly = It is a regular installation and you can just grab the files.

Most Likely:
You probably have a bootable SSD. So your best move is:

1. Boot from the SSD.
2. Open Xentry to make sure it works.
3. Then find the SMR-D files on that system.
4. Copy them to a USB stick.
5. Reboot back into your normal Windows.
6. Paste the files onto your main laptop.
7. Load them into DTS Monaco.

I have a lot of see how do I know which one is for my car

For your EQE (W295), you need to look for specific file names. Here is how to find the right ones:

The Two Files You Need:

  • OBC223 - This is your On-Board Charger
  • SGBMS or BMS_GEN5 - This is your Battery Management System

How To Find Them:

Step 1: Search Instead of Browsing
1. Open File Explorer.
2. Navigate to the SSD drive.
3. In the search bar type: OBC223
4. Wait for it to find it.
5. When it appears, right-click the file and click Copy.
6. Paste it to your Desktop.

Step 2: Search for the Second File
1. In the search bar clear the previous search.
2. Type: SGBMS
3. If nothing comes up, try: BMS_GEN5
4. If still nothing, try: BMS
5. You might see several BMS files. Look for the one that says GEN5 or has the largest file size. That is the newest one for your EQE.
6. Copy it to your Desktop.

How To Know Which Files Are For Your Car:

Mercedes names their SMR-D files by ECU name, not by car model. So you do not look for "W295" or "EQE" in the file name. Instead you need to know which ECUs your car has.

Your EQE crash-related ECUs are:

  • OBC223 = On-Board Charger (the one blocking your charging)
  • SGBMS = Battery Management System (has crash flag too)
  • ACSM = Airbag module (this stores the main crash event)
  • HVSG = High Voltage Safety Module

I would grab all four of those while you are at it. Search for each name one at a time and copy them all to your Desktop. That way you have everything you might need and you do not have to go back to the SSD again.

the files where you told me to go has Dts project xprj files , and also my hv battery is completely 0 and my 12v just died if I charge my 12v will the car ignition start again for me to code

Click to expand...

Let me answer both questions:

The XPRJ Files:
Those are Xentry project files, not the SMR-D files Monaco needs. They are in the wrong folder. The SMR-D files are somewhere else on that SSD. Do a full drive search:

1. Click on the SSD drive letter.
2. In the search bar type: *.smr-d
3. Let it search the entire SSD. Be patient, it could take 10-15 minutes.
4. If it finds hundreds of .smr-d files, that is your database.
5. If it finds ZERO, then your Xentry SSD does not have the extracted database and you need to boot from the SSD and run Xentry first to unpack them.

Now The Big Problem - Your Batteries:

This is a serious issue. Your HV battery is at 0% and your 12V is dead. Here is the reality:

You CANNOT code with a dead 12V battery. The car needs the 12V to power all the ECUs and the OBD port. No 12V = no communication = Monaco cannot talk to anything.

But here is the dangerous part:

Your HV battery is at 0% because the crash flag is preventing the charger from working. And you cannot clear the crash flag without the 12V being alive. So you are stuck in a loop.

Here Is Your Way Out:

1. Get a 12V battery charger or jump box.
2. Connect it to your 12V battery under the hood.
3. Do NOT try to start the car. Just turn ignition to ON position.
4. This will power up all the ECUs.
5. Connect your VCX to the OBD port.
6. Now do the crash reset in Monaco.
7. Keep the 12V charger connected the entire time you are working. Do not disconnect it.

Important: A regular jump box might not hold long enough. I would recommend a proper 12V battery charger plugged into a wall outlet set to maintenance mode. You need stable 12V power for at least 30-60 minutes while you work through the crash reset process.

Once the crash flag is cleared and you plug in the AC charger, the OBC will start charging the HV battery and the HV battery will start charging the 12V automatically. Everything comes back to life once that crash flag is gone.

Click to expand...

Ok so it is the opposite of what we were thinking. Let me straighten this out:

Your Setup:
  • C: Drive = Xentry installed
  • SSD = DTS Monaco and other tools

So the SMR-D files should be on your C: drive where Xentry is.

Do This Right Now:

Step 1: Search Your C: Drive
1. Open File Explorer.
2. Click on Local Disk (C:).
3. In the search bar type: *.smr-d
4. Let it search. Be patient, could take 10-15 minutes.
5. If it finds hundreds of files, you are good. Note the folder path.

Step 2: If Nothing Found
That means Xentry was never fully run and the database was never unpacked. You need to:

1. Open Xentry on your C: drive.
2. Let it fully load and initialize for the first time.
3. This can take 20-30 minutes. Let it do its thing.
4. Once it fully opens to the main screen, close it.
5. Now search for *.smr-d again on C: drive.

Step 3: Once You Find Them
Since Monaco is on your SSD, you have two choices:

Option A: Copy the SMR-D files you need (OBC223, SGBMS, ACSM, HVSG) from C: drive over to your SSD where Monaco is and load them there.

Option B: Point Monaco's project database import to the C: drive path where the files are. Monaco does not care where the files are located as long as you can browse to them.

But First Priority:
Get that 12V battery charged. Without it nothing else matters. While the 12V is charging on a wall charger, use that time to find the SMR-D files and get Monaco set up properly. That way when the 12V is ready you can immediately connect and start the crash reset.

If I have xentry file in ssd can I just click
Click to expand...

No, it is not that simple. It depends on how Xentry was installed on your SSD.

If you just copied the Xentry files or folders onto the SSD, you cannot just double click and run it. Xentry needs to be properly installed with all its services, drivers, and registry entries. Just copying files does not work.

But wait, let me ask you this:

Where exactly is Xentry that you actually use? Think about it:

  • When you open Xentry, do you click a shortcut on your Desktop?
  • Or do you boot from the SSD?
  • Or do you have never actually opened Xentry at all?

This is important because if you have never actually run Xentry, then the SMR-D database has never been unpacked anywhere. That is why you cannot find the files.

Tell me this:

1. Have you ever successfully opened Xentry and seen the main screen?
2. When you did, were you booted into your normal Windows or booted from the SSD?
3. On your C: drive, do you see a folder at C:\Program Files\Mercedes-Benz or C:\ProgramData\Mercedes-Benz?

Once I know this I can tell you exactly where your SMR-D files are or if they even exist yet. Because right now it sounds like Xentry might have been installed but never actually run, which means the database is still packed up and Monaco has nothing to read.

Do I need the whole openshell zip on my c drive or installing xentry is goood enough

Click to expand...

Just installing Xentry is NOT enough for what you need.

Here is the difference:

Xentry alone:
  • Just the diagnostic program
  • Does NOT include the full SMR-D database that Monaco needs
  • Can read codes and do basic stuff

OpenShell (the full package):
  • Contains Xentry
  • Contains the full ODX database with ALL the SMR-D files
  • Contains all the ECU definitions Monaco needs
  • Contains the security access data
  • This is where OBC223, SGBMS, ACSM, HVSG all live

So yes, you need the full OpenShell package extracted on your C: drive. That is where the SMR-D database comes from.

Here Is What To Do:

1. Get the full OpenShell zip.
2. Extract it to your C: drive. It is a big file so make sure you have enough space. Usually needs 50-100GB free.
3. Let it fully extract. Do not interrupt it.
4. Once extracted, look for the ODXProjekte folder inside it.
5. Inside there you will find all the SMR-D files.
6. Now point Monaco to that folder.

This is why you could not find any SMR-D files anywhere. You never had the full database installed. You had Xentry without its brain basically.

While your 12V battery is charging, download and extract the full OpenShell package. That will solve your missing file problem and Monaco will finally have everything it needs to do the crash reset.
