Normal Star Diagnosis vs Developer Mode

Look here: Where exactly the differences between the normal Star Diagnosis and the Developer Version lie?

Since these differences depend on the DVD version, you will get this nowhere reliable information. The Dev version contains features that are not always released for service and are therefore not available on the “normal” versions of SD. Without another license key there is nothing.
Also, some of the HW and software version of the built-in controller depends. Here are the web many halbgare information to read.

The difference is just the license key.
Other key: More rights and possibilities. For example, there are pure car licenses (Smart, MB …) but also full licenses, with which you can read and work on all Daimler products. In the service, the computers are online, that is, it is not possible to operate a computer easily with a different license

So really a developer tool is not it but that’s why … No one works with us, because we use something completely different. Not so pretty, but much more powerful and flexible than the MB Star C4. But also much error-prone, which one must avoid in the service by all means.

Also, Developermode is available in Xentry. There are a few more things you can do.

But from BR 204/212 etc Sense anyway with big what to do, because everything online. But also gives information on the Internet.

Offline SCN coding mW also with tricks normal but in practice gabs still no success, especially since no need is pending.

This Vediamo should but according to opinions of other specs probably be a good software …



“This Vediamo should but according to opinions of other specs probably be a good software … let’s see if something can be found.”

This is a pure development tool. The “normal” skilled worker or master in the branch can do almost nothing with it.
Without knowing which “commands” to execute in a particular order, garnix happens.
Did it “coincidentally” but managed to adjust ANYWHERE, ….. yes, and then ??? How do you get that back when things are not going as expected?
So without the expertise of the ECU supervisor, you have no chance.
And even the stupidest …. the necessary description files are there are not

many here in the forum are not even clear with the serial diagnosis, and that is in comparison to children’s stuff.

DTS-Monaco and Vediamo, which better

DTS-monaco and Vediamo are added to MB Star C4 software since 12-2017.

but what is DTS-monaco and what is Vediamo? And what\s the difference?

Look here:


What is DTS-monaco:

DTS Monaco is universal Engineering Tester for Diagnostic and Control Functions of Vehicle

ECUs. The name Monaco is derived from Modular Analyzer for Vehicle Communication.

DTS Monaco comprehensively covers all tasks in the areas of engineering, testing and

preparation of manufacturing tests:

*   diagnostics
*   analysis
*   OBD
*   flash programming
*   measuring
*   parameterizing
*   residual bus simulation
*   OTX

MB SD C4 DTS Monaco is based on standards such as ODX, OTX and UDS


What is Vediamo:

Vediamo Software is used by the plant engineers to develop diagnosis and engineering software, which is now used by Xentry and DAS, is based on the Mercedes Benz super engineering version developed and delivered to the general customer service dealers’ use.

The use of MB super engineering version has no limitation in diagnosis / modification / programming function are open which cannot be through the VEDOC (the original application code changes with flow) can be free to increase or decrease the SA code, modify the objective, for example: the increase of vehicles equipped with SA500 electric folding mirrors, commonly known as the Xentry and DAS development mode: open data project version in 2010 after the release, increase the number of functional limitations. So we will meet the vehicle version is too new to be into the control unit in use, or are unable to do any special modifications to the control unit.

For example: W204/2122012 instrument to modify the area family configuration, or open other resource advantage function. Diagnosis / Mercedes super engineering version of the code with code / modification / programming database using the Xentry database, so the Mercedes Benz super engineering version is determined with the Xentry version, as long as the database is new and can be used in new models.

What’s the difference of DTS-monaco and Vediamo:


Vediamo M Mode Variant Coding W212 7G

Some important tips of Mercedes Benz W212 7G M Mode Variant Coding using Vediamo.


W212 7G M Mode Variant Coding

You need:

Vediamo running with Sd connect C4

SCN coding database

Variant code:



I want to have M-mode in W212 E500 4matic 2010 model 212.090 SA801 – YOM 10/1, at the moment my variant code is Y2KX, does anyone help me to know the right code for M-mode ?


That’s interesting. I’ve got nearly the same car (W212 from 2009) and I’m also looking for the manual mode. My variant code is Y2KY.

Someone recommended to try three codings before and after the current one but I’m a bit hesitant with this.
The coding contains several properties of the car including 4Matic or RWD. In contrast to the RWD ones, the MB Star have a torque limitation to protect the gearbox etc. when starting with full throttle. Therefore, a genuine 4Matic variant code would be preferable.

I think in the 7G coding collection there was no W212 E500 with M-mode. The next “match” could be an S500 4Matic (221.086). From the thread mentioned its variant code is YE25. Not sure if this one has M-mode, though.


I want to confirm that in 212.090 with MY2010 SA801 M-mode work very well

with Y2KZ ?? Imidietly after coding there was error showed in KI display “presafe function is unavaiable” but after ignition off/on everything works!

For 212.090 MY2009 SA800 correct coding is Y2AR


SUCCESS! Now with working M-mode! Y2KZ also works for me. Same error as above after first start which went away with the 2nd start.

Test drive was successful. One drawback, however: The gear switching times in M are not better than in C or S. Some years ago, I read from an S211 (E500 M273 with 7g) which was given M-mode and the owner claimed significantly faster gear switching. He did it the official way: Changing VeDoc and MB Star C4 online SCN coding. Maybe there’s more to it than just the VGS variant coding.

Good luck

Why should you buy a Mercedes diagnostic tool with a laptop

Here list reasons why you should buy a Mercedes diagnostic tool ( MB SD Connect C4/C5, Mb Star C3) with a laptop together:

—With the Dell D630’s dedicated serial port, there was no issue for me…. it was plug and play… I just loaded the HDD from the Seller into my Dell and all I needed to do was activate WIS/EPC and XENTRY/DAS with “activation keys”… I only use the Dell for mb star sd c4 purposes…

—Bought an older Dell D630 laptop with a serial port and plan on buying MB SD Star C4 directly installed in a Dell D630 hard drive. No Virtual Machine issues.

—Mercedes Benz Star diagnosis C3 / C4 actually specifies the computer or tablet used in the SDS environment… The T30 is rather slow but will get the job done.

—If your ever in the market for a faster SDS laptop, the Dell 630 with at least 2Ghz and the speed improvement especially when using Xentry is like night and day.

—the HDD that is pre-loaded with the software for SDConnect 4 by the Seller, is inserted into the DELL D630… The DELL D630 is the fastest laptop with the RS232 feature.

—Need to connect directly into a RS232 port without using an interface – this is why I went for the complete system with laptop.

—The software Xentry/ DAS is a bit slow on an old IBM so that it is worth paying a bit extra and getting a Dell D630.

—There is a very specific set of COM ports you must use for it to work. For example you need DAS to be looking at COMx within the VM session, then VMware needs to redirect that to COMx which is a ‘physical’ serial port on your machine.

—It’s probably because it has a real com port. Most laptops these days have just a USB port and things don’t always work right if you’re using a USB to RS-232 converter. You wouldn’t want to brick a component during an update if you’re using USB. The other option would be to get a C4 system, but then they cost more. I think there are a couple other systems out there like IBM that also have real com ports.

—The PART D mux(C3) is a serial ported mux—that’s the reason for the Dell and IBM older laptops.

—The PART W mux(MB SD Connect C4) is and Ethernet/wifi connected system and that is the reason for use on other laptops—the issue is the operating system currently DAS Xentry only runs on XP.

—Plug and play!! It is more convenient for users because the software for C3/SD C4 diagnostic tool will be pre-installed before delivery.

Here are MB STAR diagnostic kits (tool+laptop) for sale:

Here are advantages of MB Star diagnostic multiplexer:

MB Star C3 Advantages:
MB Star C3 is called the best-quality Star diagnostic multiplexer.
—the most reputable/ well-received in the market;
—has a better performance and usually it will not happen to be poor connected or work stably during operation. Because of that, an increasing number of customers select MB Star C3 be their professional diagnostic equipment for Mercedes Benz cars.
—its technology and quality is developed after lots of experiments and improvement. The new version MB Star C4 need time to perfect its reliability and operation.

MB Star C4 Advantages:
The great performance of MB Star C3 is accepted by the market, while MB Star Compact-4, as a new-born and updated tool of C3, it also own its comparative advantages.
—is much different in the shape from Compact3;
—smaller in size, lighter in weight than Compact3;
—C4 2008 can do all the works what Compact3 does and it is the replacement of Compact3-Star.

SDconnect Compact 4 Advantages:
MB SD C4 overcomes the shortage of C3, C4.
—covers a wide range of vehicles including trucks and some cars that C3 and C4 do not support;
—supports wireless diagnose;
—not only support K line diagnose and CAN BUS, but also UDS diagnose protocol. Because old MB STAR C4 main board do not have UDS chip, so old MB STAR C4 can not support it;
—now use Lan cable to connect, can fit all computers (not only IBM T30);
—adopts Military quick swap technology, and supports 10,000 times pull plug, more stable;

Cloned BENZ SD C5 Connect Advantages:

—efficient diagnostic program and complete vehicle database;
—advanced upgraded VCI+ communication interface;
—support Wired/ wireless connection.
—Besides the software c3 and c4 own,it added three more software: SD Media, Xentry and Smart TAN Code.
SD Media: Video and PDF lessons;
Xentry: New software released Xentry software for diagnosing W 204,W207 and W212 which C3 and C4 does not support;
Smart TAN Code: Opened special function in DAS program with Smart cars 405/ 451/452/ 454.Besides, it also opened more special functions, such as engineer mode, remove limitations,etc, which MB Star Diagnosis Star C3 and Star C4 do not have.

W220 ESP Variant Codingwith SDconnect C4

About: Mercedes w220 ESPmodule Variant Coding, esp. for C1511-005 Coding ErrorVariant Coding is incorrect

Model:2002 Mercedes-Benz w220 s55

What is variant coding:

The variant coding in question is set by using factory data. That factory data is basically what chassis that engine control unit is bolted to. Things like weight of the car, yaw sensor and acceleration sensor parameters, moment arms, etc etc.

Once the engine control unit “learns” its variant coding, it is permanently and irrevocably locked down.

* Mercedes Variant Coding requirement:

Star diagnostic tool (better MB star Compact C4 or Mercedes BENZ C5), ebay or

A specialized laptop, second-hand ok

Working software, original/crack…both ok

(if you’re newbies, better use a diagnostic bundle, avoid lots of issues)

What is C1511-005 Coding Error:

The ESP module reads the variant coding from the ECU. Once read, its ” soft” locked.

Your trouble code suggests that the ESP module has a variant coding that differs from that of the ECU.

Is this a recent occurrence? Did you perhaps have an third party ECU tune performed? Was the ESP module replaced ? Is the trouble code stored or current ?

How to do W220 ESP Variant Coding correctly:

If you have a STAR diagnostic tool such as SD connect C4, and it sounds like you may, go to the ESP module under




Fault Codes

Select C1511-005 the right it should say CURRENT or STORED

hit F8

It should show you how many time the car has ben started after the code was detected. “0” means the fault is CURRENT, any number greater than 0 the fault should be STORED and past history. The ( obviously ) higher the number of start cycles the longer ago it was.

(If it was a long ago and a stored code, I would clear it and move on. If it is current, you can force a variant locking reset of the ESP module in STAR diagnostic and see if the code returns. If the trouble code returns, that would make it a current and ongoing error. If that turns out to be the case then perhaps the ESP module has gone “breasts skyward”.)

2.Double click C1511-005

Read the pre conditions
hit F3
read the sequence and follow it to (hopefully) force a variant coding re-read/write.

It would seem that the ESP reads the ECU on every start up. Having a bad TCU MAY be contributing to the ECU variant coding being off kilter. I would think there would be some P2000-P2564 series codes displayed for that though.

I have no training as a MB mech/tech and offer this as just a possible direction to proceed in. The ( very ) highly paid professionals at the Dollarship or the ( not so ) highly paid folks at a good independent shop should/would have the final say.
