How to use Xentry DAS on AVDI passthru?

What is the AVDI recognized by Xentry?

Xentry Passthru is different from from regular Xentry openshell. Xentry passthru does not use SDconnect toolkit. When you launch the program it will give you a dropdown where you can choose which J2534 device

How to use Xentry Passthru?

If you got the Xentry Passthru installed, there is a tool which will do the dirty work for you.

Normally it is not linked or doesnt have desktop shortcut but resides (at least in my installation)

C:\Program Files (x86)\Mercedes-Benz\xentry\bin\SelectPTDevice

IF you have installed your passthru (would that be AVDI or anything else) with correct drivers, registry entries etc it will just present you with list of options and you select your VCI from dropdown list.

Heard good things about AVDI J2534 compatibility (real thing, don’t know about clones) so it shouldn’t be a big deal. Recently i have tried to use BOSCH KTS560 as passthru and it works perfectly okay.

For curiosity, i did also test the 20-euro MiniVCI that gets normally bundled with Toyota techstream packages. to my surprise it also works albeit slow and sometimes freezes the application. This one can be actually made to work even with old DAS like 2009, 2012….it’s just matter of proper settings in cal.ini and slave.ini

For DAS/Xentry users:

Old thread – but do not run the SetPassThruDAS.exe, as it was written for DAS/Xentry for Windows XP, and not Openshell or Xentry Passthru. All you need to do is install a fresh OS (Windows 7 Enterprise x86 or x64 SP1) ideally on a physical laptop, connect the AVDI device to the USB port and run the SetupInterface_yourserialnumber_PASSTHRU_xxxxxxx.exe and Next through the setup process. If you have a current version of the Passthru software, you will see a grayed out option for installing drivers for DAS that you cannot select, but do not be concerned about that. It will detect the AVDI, and install the appropriate J2534 dll files in the Windows\System32 directory. Then continue installing your Passthru software provided on the Blu-ray from Daimler. It will take a while to install, and once it verifies your hardware ID and installs your StartKey, launch Xentry Passthru from the icon it creates, and it will prompt you first thing as to what interface you want to use. You will see Abritus72 AVDI PT (your serial number here) in the drop down box. Select that device, and that is all their is to it. Xentry should automatically communicate with the vehicle.

How to use Sdconnect C4 do Online SCN Coding?

What you can find here:

1. SCN coding compatible hardware SCN connect c4

2. How to use SCN connect c4 to do SCN coding

3. 2. SCN coding importance

1. Question: can clone MB SD C4 support Mercedes online SCN coding?
The answer is yes. Newest MB SD C4 2019.03V / 2018.12 can perform online SCN coding perfectly as long as you have online software account or buy one-time SCN coding service.

1. ) After ordering this service, prepare MB sd c4, car, laptop and TeamViewer.
2.) Send Teamviewer ID and Password to customer service
3. ) The engineer will access to your laptop to authorize SCN coding function.
4. ) After finish, the system will display “The SCN coding sequence has been completed successfully”.


2. SCN coding importance

The move to SCN coding was *very* important. There are too many configuration items in every ECU now to have someone set options by hand whenever an ECU is changed, or to understand how changes on one device have to be done on other devices. These cars are really very very complex, and unlike your laptop, if something goes wrong can result in fatalities.

There are software dependencies between different ECUs, and actually loading software into ECUs is now needed regularly – and thus so is up-to-date diagnosis equipment and up-to-date firmware disks too. A simple example is an Audio system. If you update the firmware in the COMAND unit the firmware in every other MOST device needs also to be compatible (if you want it to work reliably) and thus they all need firmware updates. If you change one component then all components need to be updated to be properly compatible.

The latest equipment even now uses ethernet to load firmware into some ECUs (so it takes 20 minutes not 20 hours).

Without SCN coding it would take considerably longer to change any control unit, would result in mistaken configurations, and thus the cost of repair (or re-repair) would go up and up as systems got more complicated. SCN coding basically allows the correct configuration to be loaded into the car.

Imagine what could/would happen if you had to “hand code” the airbag controller after replacing it? Would you trust all of your airbags to work after the local mechanic had to set all the options correctly? I certainly would not.

Your comment that “The capital cost of the latest version, plus the monthly subscription, means it is beyond the reach of many smaller independent garages” is just wrong.

If your garage has the skills to deal with the technology (and i’d argue that if they don’t they shouldn’t be doing complex things with the newest vehicles), then it is completely affordable.

If you want to work on older cars, then most independents seem to use a clone machine and use it for limited things.

The EU competition commissioner has previously taken a good look at this market and enforced rules that mean diagnosis equipment (for newer vehicles) is available at sensible prices. This is not true in the rest of the world. Mercedes diagnosis systems in USA are more expensive, and in the far east (and I think Australia) are not available at all to independents.

Sorry to be so contradictory, and in summary, but without SCN coding there would be misconfigurations and un-reliability – possibly dangerous to life – occurring quite regularly. And if you are going to need to work on newer cars, there are very affordable Xentry diagnostics systems – you just need to talk to Mercedes.

SDconnect C4 DAS Fault (1.2)-2.503.9901 (customer solution)

Phingoc in trouble:

The laptop is a Dell D630 with a china SD Connect 4.
Xentry 03/2012
DAS 03/2012

It was all working fine last i used the machine.

So.. I connect the MUX to the car (smart 451), and then the lanwire to the mux and computer. Then i turn on the ignition.

In xentry i choose Smart -> 451 -> Diagnostic -> Das opens
in das: Identify car by control unit. After a few seconds some update thing appears and disappears followed by an error.(see att.) Fault (1.2)-2.503.9901. Cannot connect to car.

Doesnt work with wire or wireless.

Please help me.

Delete the 3 “update” folders in C:\program files\SDconnect toolkit (or rename them).. then perform a repair of your SDNetControl by pressing Start\Programs\Service\Setup SDNetControl .. it will start up and ask what you want to do, select repair.. let it do its thing and then go back and delete/rename the update folders in C:\program files\SDconnect toolkit then REBOOT when its done… that should get you up and running.. it is VERY important to REBOOT after deleting the update folders!!!

Phingoc feedback:

Thank you verry much! Big Grin that fixed the whole problem.

start laptop
Rename update folders
Run setup SdNetControl
The “repair” option wasnt displayed, but it went straight into instalation. No options, but it went automaticaly to instalation :S
Reboot after instalation

Re-delete or Rename update folders after running SDNC setup

Delete setings from the MUX
Reconfigure SDconnect
Start Xentry/das and it worked straight away. Big Grin

Benz eCOM DoIP vs. MB SD Connect C4 Diagnostic Scanner

Look here: What’s the difference between Benz eCOM DoIP diagnostic tool and MB Star diagnostic Mb Star C4 multiplexer?

In summary,

New car: eCom DoIP
eCom – laboratory\development tool. Most cheap and light. Can’t be used with DAS\HHT vehicles. Need luck with kline communication. Need to be specially setup on any diag sw installation.

Normal: Clone SDConnect C4
SDConnect – workshop\robust tool. Most universal in use. The only limitation is kline communication in Vediamo from ver5* Easy to setup. In most cases work as is.

Good to know:

Actia eCOM DoIP Box Multiplexer Kit supports DoIP for the latest E and S series, and it’s perfect for Mercedes COMAND NTG5, NTG5s1, NTG5s2, NTG5.5

ECOM is the diagnostic and swipe communication interface used by daimler-benz’s production and r&d department. It supports the after sales diagnostic software Xentry, Vediamo, and the Monaco DTS, the exclusive development software, with higher access rights than SDconnect (C4).

ECom supports the CAN/DoIP network, which CAN be used for the diagnosis and brushing of new car audio and video entertainment systems. Vediamo for Mercedes engineers is an engineering software used by Mercedes engineers to develop diagnostic software, that is, Xentry and DAS now in use is developed based on Vediamo and delivered to general after-sales dealers. For this reason, using the Mercedes super engineering version is open to all diagnosis /coding/retrofit/flashing programming features. It is possible to add or reduce SA codes freely without going through VEDOC(the process of the original factory applying for modifying the equipment code), so as to achieve the purpose of modifying the vehicle equipment, such as adding SA500 electric rearview mirror.

Xentry and DAS Developer mode, commonly known as: exploit data engineering version after 2010, has added many restrictions on functions. Therefore, people may encounter that the vehicle version is too new to enter the control unit, or they cannot make any special modifications after entering the control unit. For example, the w204/212 2012 meter may need to be configured in the regional language, or turn on other convenience functions.

The database of diagnosis /coding/retrofit/flashing for the Mercedes engineer version USES the Xentry database, so the Mercedes engineer version is dependent on the Xentry version. As long as the database is new, the Mercedes engineer version can use the V4.00 version on the new model, and compact3 & SDconnect does not support the ODX document. The latest V5.00 supports ODX files with eCom. It is recommended to use eCom with DoIP function, which is faster and more stable.

How to make Xentry PassThru work for New Models (Euro5/6, W205, W213, W222)

Something good to help you to make Xentry PassThru on Windows 10 x64 support new Mercedes models (Euro5/6, W205, W213, W222). Done with VAS5054A PassThru Driver
Xentry PassThru needs to be installed on Windows x64 to support new models, such as Euro5/6, W205, W213, W222 … However, VAS5054A didn’t work on 64bits as passthru. There is 64bits device driver for VAS5054A but there is no PassThru driver working on 64bits. You may try Actia driver instead but this is a patched 32bits PassThru API files with 64bit device drivers working on Windows 10 x64. Xentry recognizes it and works with W205 (confirmed), etc.
WARNING: Use it on your own risk, only for test purpose.
What you need:
(1) VAS5054A Bluetooth hardware. (genuine and good clone… both ok)
(2) (option) VAS5054A EDIC_PDU_API 1.20.4x driver installation file. You can find it somewhere on this forum.
(3) (option) New firmware. The firmware included here is version 1.20.41 for better compatibility, not 1.20.42.
(4) Softing_VAS5054A_PassThru_Driver_x64_v3.zip (attached here)
(5) 64bit Windows 10
(6) (option) DC 12V power adapter, 2 jumper wires for temporary power.
Pre Installation:
(1) Install Xentry PassThru and do all patches.
(2) (option) Install EDIC_PDU_API 1_20_42 driver (or EDIC_PDU_API 1_20_41). It’s for installing .NET framework or VC++ redistribution files.
If you are going to do clean install on fresh Windows 10, you might want to install the EDIC_PDU driver first. It installs .NET framework, VC++ files, some EDIC DLLs on /Windows/System32 or SysWow64. Other files will be overwritten by the below manual installation.
(1) Copy “Program Files (x86)\Softing\*” to your HDD “C:\Program Files (x86)\Softing\*”
(2) Copy “Program Data\D-PDU API” to your HDD “C:\Program Data\D-PDU API”.
(3) Double click on “Softing_VAS5054A_PassThru_1_20_042.reg” and install it.
(4) Make a shortcut of “SftngCM.exe” on Desktop.
(5) Right click on “C:\Program Files (x86)\Softing\EdicDriver\win7\softingedic7_ntamd64.inf” and install.
(6) Connect the VAS5054A hardware using an USB cable. Connect it to a temporary power(12V DC adapter) or OBD-2 port.
(7) Check “Control Panel/Devices Manager/Softing…”. If not installed correctly, update the device driver manually.
(8) Make a shortcut of “EDICConfig.exe” on Desktop.
(9) (option) If you have newer version than EDIC_PDU_API 1_20_42 driver and genuine VAS 5054A hardware, you may install the API driver now.
Post Installation:
(1) Connect the VAS 5054a to a temporary power(12V DC adapter) or ODB-2 port.
(2) Run “SftngCM.exe” on desktop as administrator. Make a “C:\Temp” directory if not exists. This is for saving log files. If not exists, SftingCM.exe will cause error when doing test.
(3) Choose “VAS5054A” and type the serial number (maybe 0821xxxxx).
(4) Select “Test” and click on “Start Test”.
– RED dot : PC <-> VAS5054A does not communicate. Something wrong on your driver.
– YELLOW dot : PC <-> VAS5054A communicates.
– GREEN dot : PC <-> VAS5054A <-> Vehicle communicates.
(1) “.NET Framework 2.0/3.0/3.5” needs to be installed if not installed automatically. You can install it by selecting on “Control Panel/Programs and Features/Turn Windows features on or off/.NET Framework 3.5(includes .NET 2.0 and 3.0)”. You also need to install VC++ redistributions if not done yet. (MSVCR100.dll, mfc100.dll, … errors)

(2) Temporary power to VAS5054A for test purpose : Ground to either pin 4 or 5. 12V DC to pin 16.

(3) You can upgrade the EDICDriver in “Program Files (x86)\Softing\EDICDriver” if you have newer version. Update the device driver on control panel.

(4) If you installed newer version EDIC_PDU_API driver than 1.20.42, edit the *.reg and change the number 1_20_42 to your number (for example, “EDIC_D_PDU_API_1_20_042” to “EDIC_D_PDU_API_1_20_0XX”). After editing, double click on it and install it again.

(5) If your device has different serial number but SftngCM.exe doesn’t allow the change, edit the *.reg file with text editor, double click on it and install it again.

How to



(Solved) SD connect C4 NOT Connected via LAN or WIFI

Here are optional solutions for those with a Sd connect C4 but cannot be connected via LAN (or wifi).
Operation system: Window 7
Static IP: 172.29.127.xxx
Battery: the 6 batteries are installed, fully charged

Error message:
when I connect it to the MUX (the 6 batteries are installed) it tries to connect but it gives up after a minute or two and I have a yellow triangle over the network icon in the taskbar.
The display on the MUX shows that its number is 00, it also displays a cable icon and a countdown timer and the message “Device not in use”
SD connect C4 NOT Connected via LAN or WIFI

The display doesn’t show the wifi option, only the cable icon.
When I start SDConnect Administration Toolkit it says the MUX is not cable accessible.

Possible solutions from users:

Option 1: LAN adapter
Open it and check the LAN adapter soldering if it gone loose

SDConnect relies on broadcasts/multicasts (like the DHCP protocol) to discover SDConnect devices.  They can be con completely different subnets and be “detected” but you cannot interrogate or configure them until you get their IP addresses configured for basic management setup.

Option 2: Toolkit
For Connection you´ll need the Toolkit.
WLAN is not seen until configured, if you reseted the SDConnect you´ll need to reconfigure it with the Toolkit.

Option 3: Battery
You may try forcing your NIC in your laptop to 100Mb/Full Duplex, as many will default and negotiate to 1Gb/s, which I don’t believe some of the SDConnects talk over too well.

Also, FWIW, I have been getting an error 750 when trying to communicate to the SDConnect recently.  The connection seems very unstable. I have only used a direct Ethernet connection.  I have not investigated it very much, but I have resorted to the C3 for right now, which has never failed with 1.2012.
I reset it back to factory settings as well.  I have not had an opportunity to investigate it to any extent, so I am unsure what the problem may be, but SD NetContol is stating a Network Error to the SD Connect. It is all connected via CAT6 and no WiFi.
It is best practice to remove the batteries form the SDConnect when not changing firmware or leave them in there?  I have quality rechargeable batteries I use and typically leave them in when changing firmware, but I have left them in for a longer period.  When I removed the first set, the batteries clearly leaked but didn’t appear to damage the SDConnect and I throughly cleaned it and it has worked since them.

How to Slove MB SD C4 Cannot Access OBD2 Port

​When using china clone mb sd connect compact 4 Multiplexer, it could not link to the car computer, MB SD Connect C4 offered a message, saying like “check cable connection / turn ignition on”. Then tried again, clone SDconnect compact 4 multiplexer cannot access OBD2 port

According to customer’s feedback that he failed to access to the diagnostic OBD port when tried to use sd connect c4 read errors code from Benz SRS system. The system prompted an error message “check cable connection/turn ignition on”.
Possible Reason:

The error lies on the SD Connect C4’s battery.
​Solution from CnAutotool.com:

1) Check and record your MB SD Connect C4 multiplexer battery
2) Hook up a digital multimeter to set it to the direct current
3) Get two t-pins and plug them into the OBD socket at PIN 5 and PIN17 position
4) Put your positive lead to PIN16 and negative lead to PIN5.
5) Write down the voltage on the digital multimeter
6) Check if the voltage you from PIN16 and PIN 5 is same in step 1.
7) Find the light green wire with a blue tracer band of PIN10 of the OBDII connector.
8) If the voltage differs in step 1 and step 6, the problem is probably with your battery.
9) If the battery is damaged or broken, please replace your battery.

Clone Xentry Connect C5- Good & Bad Things

I bought “Original Clone Xentry Connect C5” from China’s retail store in 2017/12.

Good thing:

1. Unlike bad products of mercedes diagnostic tool C5 type C4 motherboard, texture is good
2. DoIP specification

Bad thing:

1. Because it is VM system + 32bit, the reaction is slow (SSD though …)
2. Vediamo can be used, but feeling like driving with DELL D 630 (unsuitable)
3. The DTS Monaco software is installed but the connection with the vehicle is NG (currently retail stores and manufacturer engineers are thinking about how to fix it)
4. Passwords are applied to each drive, making it hard to customize
5. Retail shops and manufacturer engineers lack knowledge (take time to support)

My thoughts

I think purchasing this product is still early.

There are too many trouble elements.

I’ll report it when the situation changes.

What I currently use (stable and comfortable)

New car: eCom (64 bit)
Normal: Clone SDConnect C4 (64 bit)
Old car: Star C3

Best regards
