Since C4 will be banned (or already is) in the latest versions of Xentry, and most new laptops no longer have LAN/Ethernet ports, I decided to switch from a LAN-connected C4 to a USB-connected VCI.

You can use a WLAN or USB-LAN converter, but it's still a C4. As for WLAN, I know that new devices and computers have fast WLAN, but in this case I'm very old-fashioned, I always use a wired connection. If you've ever seen a control unit that failed due to a WLAN flashing process, this will forever be etched in your memory.

Of course, you can modify Xentry, or more accurately the toolkit, in such a way that you can still use C4, but at least in the long term I don't see that as a choice.

Which model to choose? Alternatives to C4:

  1. New Mercedes VCI C6 (i.e. Bosch MTS6532 with special Mercedes firmware and modified housing with Mercedes branding)
  2. Used or refurbished Mercedes VCI C6
  3. Cloned Mercedes VCI C6
  4. VXDIAG VCI C6 or SE
  5. Any J2534 device like Openport, Scanmatik 2 PRO or MDI
  6. Super MB PRO M6

There are still a few multiplexers on the market, but some of them are C4 clones in other housings (eg C5) and are out of production again or replaced by VXDIAG devices or J2534 dongles.

My requirements for the multiplexer are as follows:

  • Can be used with XDOS
  • VCI should work without additional software or drivers
  • Administration must be performed in the Xentry system configurator, so in this case it should be done using the VCI Manager

So, with these requirements, I settled on a VCI C6 clone. The original VCI is too expensive (3000 euros and up) and at least here in my country, it is not easy to get. Some of the used or refurbished C6s are in an affordable price range (1600 euros and up), but still very expensive, and some without warranty or return options. The VCI C6 clone (around $450) is still a risk, since it is almost impossible to return the device to China, but the loss of money is much less.

Why did I abandon VXDIAG, Openport and other options?

I had the VXDIAG kit, and it wasn't cheaper than the other options, but it was more difficult to use. If you forgot to renew your license and you're somewhere without an Internet connection, but you need to do something with the car, it's a real pain in the ass. So I skipped all those options. VXDIAG never worked with Vediamo anyway, or at least I didn't have the brains to make it work. So that was another argument against any VXDIAG options.

Some ultra-low-cost systems come with Openport, but it's a J2534 device that only works with the PassThru version of Xentry. Maybe I'm old-fashioned too, but I decided to use the XDOS version, so J2534 devices weren't an option at all. I also avoided MDI or Scanmatik devices.

But I have a clone of the Opel MDI device, and it works fine with GDSII on a separate laptop. It is connected to the Internet, and I also installed MBTools on it. With this combination (Dell laptop, MDI device, MBTools) I can use MBTools on any Mercedes, at least for now.

I also have a Super MB PRO M6, it shows that it is something different than C4 but in the end it is just a clone of C4. The new versions seem to be modified but I haven't checked them anymore because of the brick I bought from them in the past.

My experience with VCI C6 clone so far.

The clone has been running for some time now (3 months) with Xentry OpenShell version 09.2023 and compared to the C4 it is significantly faster and more stable than a regular MUX. The original VCI C6 comes with a separate WLAN USB stick. In my case the clone came without a separate stick. It is administered in the VCI Manager in Xentry, no separate drivers or software are required. When my C6 arrived it did not work at first, but the seller provided a new firmware via TeamViewer and it has been working stable since then. The only cables that come in the box are a 3m USB cable and an OBD connection cable. There are no other cables for connecting to the old 38-pin connector or for Sprinters. There are no cars in my range that need these connections. I'm not sure if there is an adapter or other solution to connect to older cars with C6. As far as I understand, the original version supports older cars, so I expect the clone to support them too.

The price of the VCI C6 clone is almost the same as the C4 and I believe most users will eventually choose this device if they have the same requirements as me.
At the moment I can recommend the VCI C6 clone. For any questions, please contact me or write comments.

Thanks for reading! Just some updates.

It still works fast and stable with XDOS 09.2023, I will install XDOS 06.2024 and configure everything so that VCI C6 can be used with it.
In Vediamo the device is connected and configured as eCOM, the serial number is displayed correctly, in DTS Monaco the same.
Sometimes some operations end with the error "NRC 22". I have not yet been able to find out whether this is a security problem inside DTS Monaco concerning the control unit or whether it concerns the C6. All operations performed by XDOS are done well, so I don't have any errors yet, only DTS Monaco sometimes works unsatisfactorily.

I have a separate system with 09.2023 XDOS only for C4. All operations with DTS Monaco complete successfully.

I also have a problem with MBTools, sometimes I can connect to the car and sometimes I can't (same car). I will stick with this and report more results.

I have VXDIAG C6 Bosch MTS6532 with lifetime update for Xentry and it works without any problems.

Thanks for reading. I'm updating again.

I ordered the TabScan T6 Xentry. Mainly because I wanted to try the iOS app that was provided. But also because I was curious if there were any differences between the VCI C6 clone, SD C4, and T6 Xentry. Having tested and played with all 3 multiplexers, I can say that yes, there are very significant differences in speed and stability.

The slowest unit is the C4. It takes much longer to access the car with the Xentry 09.2023 (2017 S205).
Next up is the VCI C6 clone, which is much faster than the C4 with the same system and car.
But the T6 is much faster, and the short test starts quite quickly.

If anyone is interested, I will write more about T6 in another thread.
 
If you like coding and full diagnostics, you can not use any Passthru driver, whichever you use, the result is the same. Simple diagnostics, no full coding, Passthru is an OEM port that does not give access, another thing is the original matrix for C4 and a new real (not Chinese fake) C6.
 
What are the limitations? I had the original equipment too and didn't notice any difference.
With TabScan and C6 clone I coded some elements in some control units. Everything worked fine, the last mod enabled Last Mode on my S205 220D MY2017.
 
Well, the difference is in the ports in Xentry, for full diagnostics and full coding with XENTRY VCI now (or SDconnect before) it uses the original driver that is integrated into Xentry. Openport 2.0, like any Passthru, is a universal port for any J2536 driver, and they are not the same. If you want to do full coding, you will get limitations in other modules and actuators, do coding in the restyled W213, then you will understand what I mean. Passthru is a universal port for After-Sales Workshops for light diagnostics. XENTRY VCI uses the original port, not Passthru, and has full access. That's the difference!
 
I agree with you, Openport has a security level of 3, not 9 or 10 like C4 or C6.
C4 clone is considered genuine, same levels possible, C6 clone is considered genuine by Xentry, I can even upgrade it. So I think this is at least something we can work with. If I need more I'll buy a real C6, but for now it works for me and is worth the money I spent on this equipment.
 
I want to write that I noticed that VCI C6 OEM works as eCOM, it is not stable with new cars, especially with W223. Also it can not be used for coding with MBTools, because it does not recognize it! So for me it is just another piece of crap! I also use VXDIAG VCX, it is God in Xentry multiplexers!
 
I use Super MB PRO M6 and so far there have been no problems.
It works well with both new cars (Xentry 09.2023) and old cars (HHT) via SDconnect (not VCI).
There is a small cooler inside that can be a nuisance, but in a normal garage/workshop you won't hear it.
The current consumption is about 0.6A, so the battery does not discharge as quickly as in older versions.
WiFi works great/stable.
