3.SD Connect C4 dead, not power up (customer solution)
Share an easy way to repair SD connect c4 multiplexer
if your multiplexer is dead, not powering up via any adapter cable.
First open the MB SD C4 main unit. Slide PCB out a little bit, from the connector side, so you can see the units buttons wiring. Carefully pry the lock out & up, after that you can pull the wiring and PCB out.
Then Open 4 Main PCB screws, Carefully wiggle the PCB off from another, it might be pretty tight, so carefully, side from side!
Disconnect the LAN cable, carefully, pretty easy to break the small clip.
Then you can disconnect the Connector PCB, very carefully, might be really thight! Again slowly from both sides. You now have access to the small Fuses.
You can use multi-meter to see if they work, usually the LAN connector side 5A is burnt. So desolder the broken one, install new & enjoy your powering up mux again!

7.How to solve Xentry Internal Error (3.17)-3.175
Here is a customer solution to Mercedes MB Star diagnosis SD Connect C4 Xentry Internal Error (3.17)-3.175.
Internal Error (3.17)-3.175
Please contact the Star Diagnosis Call Center
Error Analysis from customer:
this error only appears when your lic_key_2.dat file is marked read only.. but if you have to have your laptop connected to the internet (like I require for work) then when not set read only, Xentry deletes the contents of this file requiring you to reenter your key every time you run Xentry.
make sure the C:\Documents and Settings\All Users\Application Data\LicDir\lic_key_2.dat file is NOT set to read only, and completely disconnect from the internet.
(for those of us that require internet connections for work)..
copy C:\Documents and Settings\All Users\Application Data\LicDir\lic_key_2.dat to the desktop.. rename it to lic_key_2.x4711.. copy it back into the directory. make the lic_key_2.dat file NOT read only.. make the lic_key_2.x4711 file READ ONLY... This seems to keep the nasty error from returning, but still gives the long time for Xentry to close error.
8.Xentry/DAS error Fault (30.3) No valid DAS license (solved)
Here are some tips for Mercedes MB Star diagnosis SD connect c4 or MB STAR C3 users when they run DAS but meet with
You can try to:
change your PC date backwards; then you will have to fix Xentry.
need a complete set of new keys--------ipput via star utilities, because you switched computers your MAC and LAN Address changed
Still not solved?
CareUCar engineers think that you should activate your Xentry/DAS software with the help of the dealer.
Send to the dealer:
Hardware ID XXXX-XXXX-XXXX-XXXX-XXXX-XXXX-XXXX-XXXX
HW-ID XXXXXXXXXXX APPID XXX
XENTRY activation manual:
Run “Get Hardware ID”
COPY HW-ID:XXXXXXXXXXXX & APP-ID:XXX in Startkey Center
Then Startkey will be sent back.
Paste the Startkey and activate Xentry.
DAS activation manual:
Run “Get Hardware ID”
copy the generated hardware ID to the dealer for the license.reg file
Run Mercedes software always in the same laptop; otherwise you need to re-activate software after laptop change
No valid DAS license; DAS will now be closed!
8.SD Connect C4 WiFi No Connect to 2016.5 Xentry (Solved)
When I run my MB Star diagnosis SD Connect C4 with cable in Xentry 05.2016 everything works well. I made configuration the WIFI of PC with the normal procedure with 26xa ec. but when i tried to connect my Wifi of pc with the MB SD C4 I got error that there is no connection. i tried different times but nothing happened. The sdconnect is on standby but my PC doesn’t see the Road24h. After a little bit of time in my network connection i can see the Road24h but when I try to connect it gives me error and than the Road24h is not anymore in my network connections.
Finally, I solved by following this step-by-step instruction:
It worked for me
To save an ad-hoc network and its network key on the guest computer (running Windows 7)
Note down the SSID, security type, encryption type and the key of the ad-hoc network.
Disconnect your connection to any wireless network and switch off/disable your wireless device. Turn on/enable your wireless device but don’t connect to any network. (Thanks GK.)
Click on the network icon in the taskbar.
Click Open Network and Sharing Center > Manage Wireless Networks > Add.
Click “Manually create a network profile”. (This may look silly but we really are going to create an infrastructure network now.)
Enter the network name (SSID), security type, encryption type (if any) and the key that you noted in step 1.
Uncheck both checkboxes (“Start this connection automatically” and “Connect even if the network is not broadcasting”.) [Note that you cannot have the connection start automatically. If you try to have it checked, step 10 will fail. A different way to start it automatically during system boot is described below.]
Click Next > Close. Your connection must appear in the list with the icon suggesting infrastructure (two big screens connected to a tube). Don’t worry about it.
Click Start, type in “cmd” in the search box, press Enter.
In the Command Prompt, type in “netsh wlan set profileparameter name=NetworkName ConnectionType=IBSS”, exactly as shown, without quotes, except you must substitute NetworkName with the SSID (network name) of your ad-hoc network.
If everything went well, you’ll see that the icon has now changed to an ad-hoc icon (three small screens connected to each other) in the Manage Wireless Networks window.
Turn on/enable your wireless device, and try connecting to the Ad-hoc network. You will notice that you no longer need to enter the network key.
To automatically connect to a saved ad-hoc network during Windows boot (can be applied to both guest and host computers running Windows 7)
Click Start > point to All Programs > right-click Startup > click Open. (You may choose Open All Users instead if you prefer).
Right-click an empty space and click New > Shortcut.
Type in “netsh wlan connect NetworkName”. Once again, NetworkName must be substituted with the SSID of your ad-hoc network.
Click Next and enter a fancy name such as “Connect to NetworkName” or something like that.
Click Finish and you’re done. This shortcut will run when Windows starts up, giving you a very brief flash of the black command window, followed by your computer connecting to the ad-hoc network if it is available. Tip: You can also pin the shortcut in your taskbar or copy it to the desktop to easily connect to the network any time you want.
Note: You will probably need Administrator access to complete some of the steps above (in both procedures).

11.How to Connect the Wires from MB SD Connect C4 MUX?
I've got a -95 W124 and would like to connect my Star diagnosis SD Connect4 to it. But I do not know how to connect the wires from the SDconnect c4 mux?
The Black plug is of course ground, which will go in pos 1 on the Data Link
The White plug is marked KL15 which I understand is going to pos 16..?
The red plug is marked 12V B+, don't know where this goes.
The blue plug is marked K-Line/LIN, don't know where this goes.
There is to groups of plugs with two plugs in each. One Green and one yellow. One group is marked CAN HS and one is marked CAN LS. The green plug in each group is marked CAN_L and the yellow is marked CAN_H.
Here is the solution I found on a forum. I have tried it successfully as follows:
Connect Red to +12v battery directly, White to pin 16, Black to pin 1, and Yellow to pin 8 (some motors like M111 series) to get HFM error and live data,
Pin 7 for HVAC, Pin 6 for airbag etc.Result:
After trial and error a gazillion times, this is what we ended up with, and the software actually responds!!So it seems the BLUE jack, marked K-Line, is the one you'll have to move from pin to pin according to the software's instructions. Mission accomplished
Hope it helps you out also.
12.How to change Xentry/DAS language to French
Here is the customer solution to Mercedes-Benz MB Star diagnosis Xentry/DAS language change (Russian to French)...
Actually, i can't change the language of das/xentry at the beginning:
Xentry is in Russian and DAS in English
(ewa.net Russian too)
i first checked if i have the complete language pack installed, because if not i wouldn’t have all the data for other languages.
Then i was told that:
“If you right click the DAS icon on your desktop and select "properties", at the Target line you can read "-lru" where "ru" refers to Russian language.
If you change this to "en" (I think gb works too), you will have DAS in English. If you want some other language, you can find the list of language codes from the forum.
A similar change would be needed for DAS SIM shortcut.”
Follow the tips, i made it.
Xentry was in Russian and now after change language in settings is in French
DAS was in English and now after change the "Iru" to "Ifr" it's in French too
It's nice too!
But in Das, i had all " é " replaced by a Russian letter i don't have in my keyboard it's look like an " N " inside out.
Checked Windows Regional settings... The keyboard was set to some Russian mode.
Now it's in French mode and it's ok
The French Xentry/DAS works like a charm!
