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 SD connect 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 MB SD Connect 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 use Sdconnect C4 do Online SCN Coding

What you can find here:
1. SCN coding compatible hardware MB SD Connect C4
2. How to use SCN connect c4 to do SCN coding
3. 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.

Source 2:

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 dependancies 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 the 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 mis-configurations 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.

Mercedes Benz Star C3C4C5 Buying Guide


Mercedes benz star scanner is a very popular auto scanner in the market. However,Many customer are confused to choose when they want to buy one, because there is four version of mb star:Mercedes Benz star c3,benz star c4, Benz Star SD Connect Compact 4 C4 and super MB benz star C5.

So now,i will summarize their similarity and difference,hope it will helpful for customers to choose.


1.Benz star C3/C4 and MB star sd connect c4,Super MB Star c5 use same software.

V2019.3 MB SD Connect Compact C4 Software WIN7 500GB HDD DELL D630:


V2019.3 256GB SSD Software for MB SD C4/MB SD C5 MB Star DELL D630:


2.For the hardware, Benz star C3/C4/C5 is same function in diagnosing.


1.For the functions, MB star c3 and c4 are almost the same,C4 can do all the works what C3 does and it is the replacement of Compact C3.
Just benz star c4 size is small and weight is light,much convience and the anti‐interrupting ability is better.
One more thing, as customer feedback, the advantage of c3 is can do trucks best.

2.MB starC3, C4 just can support Mercedes Benz cars manufactured after year 2000. Super MB star c5,Benz SD Connect C4 can support all current and new coming MB vehicles.

3.Benz star c3,c4,SD connect C4 update by Harddisk.That means when customer want to update,they need to send back harddisk to supplier,after finish update,then send back to them again or just buy a new HDD.For the long international distance,it may need about 2 weeks can complete one time update,so it is very trouble and inconvience.

Under this suitation,Super mb benz star c5 is release, it is can update through super mb star official web directly, which will be much convience and time saving.

In addition,Super mb star C5 work with W204, W207, W212, 405, 451, 452 and 454. 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 by Benz Company after 04/2009 by diagnosis new cars. 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 Star C3 and Star C4 do not have.

4.Now we turn to MB star SD connect C4 again.MB Star SD connect C4 not only support KL diagnosis and three lines CAN BUS diagnosis, but also support UDS diagnose protocol, Because it have UDS chips. Star C3,C4,c5 don’t have this chip, so they can not support UDS.

The most advantage of SD connect c4 is: It can connect to PC by wireless or Lan cable.So it will be much more convience than Benz star C3/C4/c5.

Besides, Professional Diagnostic Tools mercedes star diagnostic SD connect C4 interface components used the military quickly inserted techniques that can support one million times plug, more stably;And all of the its core components adopt new original packaged chip, plus 24 hours fatigue test, to ensure its stable release.

So in all,each version have its advantage,just see which one is most suitable and interested you.

Exploring the MB STAR C3

This thread will be devoted to a thorough explanation of the Mb Star C3 system in depth, over time. Another good reference thread can be found here.

First off, some history and background about the system. The MB STAR C3 is a diagnostic system that is provided by the factory for dealerships and independent repair shops, and is used to interface with the cars’ computers to diagnose systems and pull/reset codes, and even to program certain elements of the systems on more modern cars. The system costs upwards of $20,000 from OBD2TOOL, and is applicable for MBs from model year 1989 and newer.

Of course, cars of model year 1989 only had 2-3 computers in the car; however all successive MBs have had an increasing number of computers, and this is where the MB STAR C3 system really comes into its own — with the newer cars. For the purposes of the cars that are the focus of this forum — the 124.036 E500E — and to a lesser extent the 400E/E420 and the later C126 coupes, the computer setups are rather crude and limited when compared to cars starting with the W210 models, which debuted in model year 1996 in the USA.

What I’m saying is that the MB STAR C3 systems are much more suited and capable, coming into its own, the newer the car that it is used with. However, the good thing is that it is able to fully exploit the built-in computer diagnostics as found in the E500E. It does this using a compatibility mode that emulates the Mercedes-Benz Hand-Held Tester (HHT), which was a diagnostic tool that was used for the 1989 and up cars, commonly until about 2001 when the MB STAR system debuted. The HHT is literally a hand-held unit (it is actually quite a handful) that allows the user to pull and reset codes, provides access to “live” engine data on the M119 and M104 engines (though a larger array of live data on the M119s), and generally pull compete diagnostics of the computer systems.

Mercedes Hand-Held Tester (HHT)

The MB STAR system, when it made its debut, was much more capable because it was PC-based (IBM T30 laptop), but it was also very versatile because it incorporated a HHT emulation mode (for backward compatibility) along with a “multiplexer” intermediate unit between the PC and the car, which allowed the connection of a variety of different diagnostic connection cables, depending on which diagnostic system the car in question happened to use. For the oldest cars (i.e. the C126, early R129 SL models, early W124s and W140s, etc.) a “four-pin” diagnostic cable was provided. For second-generation cars, such as the E500E, 400E/E420, middle and later R129s, middle and later W140s, the familiar “38-pin” plug is provided. There are also OBD-2 interface cables for model year 1996 and later cars, as well as a 14-pin cable for European diagnostic systems. All of these cables allow the combination of the MB STAR with the in-line multiplexer unit to fully interface with any particular car’s computers.

As I said, the MB STAR system debuted around 10-11 years ago, in 2001. Because of its expense, it has been very much “out of reach” of most MB owners and enthusiasts. To pull codes and get information about the car, owners were forced to buy limited testers from companies like Snap-On, Trisco, and others that perhaps allowed one to pull and reset codes, and a couple of solutions provided some limited “live data” where the car allowed it. These systems would typically run from $500 to well over $1,000. The other option was to somehow obtain a used HHT (they are occasionally available via eBay, and are quite expensive) or a used MB STAR system – still a huge expense of multiple thousands of dollars used.

In recent years, Chinese forgers, who excel at making fake copies of everything from Louis Vuitton purses to Guess Jeans to Rolex watches, have set their sights on the MB STAR market (and other automotive diagnostic systems for other marques). This has resulted in a cottage industry whereby one could purchase an MB STAR system for anywhere between $600 and $1,200. Over the past year or so, as Chinese copies of the MB Star C4 system have come onto the market, the prices of the MB STAR C3 system have come down to a typical range of $250-450, depending on the vendor and the items included in the package.

These “clone” systems are easily available on sites like eBay and also Alibaba.com from hundreds of vendors. As with any Chinese copy of anything, quality varies and quite often — but not always — one gets what they pay for. The recent reduction in price of the MB STAR C3 systems has made even relatively good quality systems very very affordable for the DIY mechanic and/or MB enthusiast — providing them with the same diagnostic power as the dealership mechanic (but not the same level of training and knowledge). Typical options that are available with MB STAR C3 systems available on the Internet include: an array of cables; a multiplexer; a hard drive containing the MB STAR software package; and instructions on how to set up the system. The software typically includes: MB Xentry, WIS, EPC, STAR Utilities; EWA net; Star Browser; Star Finder; and a recent MB parts price list (which goes out of date quickly). Quite a number of vendors also provide Internet support, including the ability to remotely control systems over the Internet (with the user’s permission, of course) to diagnose installation and software problems.

There has been precious little information on the Internet about the Chinese MB STAR C3 systems, how they operate, and in general how the system operates. This thread will be a thorough, methodical investigation of how the system works, what it looks like, and how it can be used with the E500E (and by extension, the 400E/E420). It is up to the individual owner as to whether they need or would want such a unit. It would be overkill for many if not most owners. However, there are a number of owners who do want to do their own maintenance and want the tools to help them do this properly. For these owners, purchasing an HHT or MB STAR system may be a good idea.

I will not go into the nuances and details of ordering the system. All that should be said is that one should do their research carefully, and pay attention to the ratings from other buyers as to the honesty of a particular vendor. Most of these vendors are based in Hong Kong or on Mainland China. Quite often they speak decent English and are quite responsive and communicative when inquiries and requests are made. It would be recommended that prospective buyers utilize an escrow service to complete the transaction, so as to maximize honesty and straightforwardness of the transaction from both sides.

Some vendors offer free air-mail shipping via DHL or other international shipper. These packages can arrive in as little as three or four days after a payment goes into escrow and the seller is notified by the escrow company that they have received the cleared payment. Once the package is received by the buyer, they inform the escrow company that the package has been received in good order, and the money is then released to the seller. Pretty seamless, and because of the escrow service — a fairly safe transaction. Certainly better than sending off a Western Union or Credit Card payment to an unknown party in a foreign land.

So, the photos below illustrate what is commonly received with an MB STAR C3 package. It is a 4.5kg (10-lb) box that is nicely packed, and includes all of the items described in the seller’s site. A typical package will include the cables, a USB hard drive (or internal hard drive for an IBM or Dell computer, if specified), a multiplexer box and a packet of adhesive stickers that are placed on the multiplexer and the computer-to-multiplexer cable. The box is unpacked and the contents are checked against the web site’s description to ensure that all contents were included. Some sellers also sell individual pieces of the sets, if they are ever needed.

Next, after the contents of the package are ascertained to be correct, the recipient should install the software on a computer. It is HIGHLY advisable that a standalone, separate laptop computer be used for this, seeing as it will be used in a garage (next to the car) environment. For versatility (and because most people don’t own the specific IBM and Dell laptop models that are needed for the internal drives) it is advisable that the buyer specify the external USB hard drive model of the MB STAR C3. This way the hard drive can be plugged into any qualified laptop and used.

Requirements for a laptop that can be used with the MB STAR C3 system are generally as follows:

Must have a SERIAL port
Must have a processor frequency rating of 1.8 GHz or higher
Must have at least 1 GB of RAM; more is highly desirable
Must have a USB 2.0-compatible port
Must be running Microsoft Windows XP

It is best to just purchase a used laptop via eBay or Craigslist that meets these specifications, and use this computer SOLELY as a DEDICATED computer for the MB STAR installation. It can be kept in the garage and used for these purposes. It really doesn’t even have to be connected to the Internet. One can also put the laptop on a dedicated cart, which allows the computer, cables and a printer (if desired) to be rolled around the workshop/garage next to specific cars. Although the cables are quite long, it’s nice to have the computer next to the engine when using it.

Top Alternatives to Mercedes Star Diagnostic Scanner C3 & C4 Tool


In our opinion, there are better alternatives for those who like to do their own troubleshooting. Whether you are a repair shop a Mercedes-Benz owner consider these scanners as well.  Note that we do not endorse any of the following OBD II / CAN scanner brands. Links to obd2tool.com listing are provided if you need to check current prices.

If you are looking to purchase a Star Diagnostic System with Xentry for Mercedes-Benz there are a few things you need to consider.

Learning Curve: In order to use the diagnostic scanner properly you need to learn how to use the Xentry software. While reading, clearing fault codes is not very difficult anything besides that requires that you have proper training. Yes, you can find a few guides online on how to perform certain programming using Xentry but if you don’t perform the programming accurately you may end up causing more problem than you solve.

Consider Genuine Scanner: The only problem is that they are quite expensive and require a yearly license. If you are considering to buy a clone of the scanner made in China keep the following concerns in mind.

SCN Online Coding: Unless you buy the scanner from the official Mercedes-Benz source, you will not be able to perform SCN coding of control units. That’s because Mercedes Star Diagnostic scanner will try to connect to Mercedes-Benz database for verification of SCN code in order to program certain control units. That is not possible unless you have purchased a valid license. With that said there may be some basic coding and programming of control units that can be done but this programing can also be performed with other advanced scanners.

Mercedes Star Diagnostic Problems with Software (Xentry) VM Ware Installation: All the setups that you see for sale that state that they use VMware environments are not legitimate hardware and software. Besides the fact that these scanners are not legal copies, they are also prone to crashing and run much slower than direct Windows installations. Yes, you are required to have a Windows XP with a serial port for the MB Star Diag C3 scanner. Many VMWare Mercedes Star Setups experience problems some of which you can see posted on this site: MB SD C4 C3 problems and solutions.

License: In order to get the full features offered by Mercedes Star diagnostic scanner you need to sigh up for a yearly subscription and pay a license fee. This is not financially feasible if you only work on one or two Mercedes-Benz models. If you end up buying a cloned version of the scanner the Xentry software key will expire in a few years and you will not be able to use your scanner at all.

eCom Compare with SD Connect C4

Here is some feature about eCom, MB Star C4 and Xentry Connect . Hope can help you choose right tool.

eCom – laboratory\development tool. Most cheap and light. Can’t be used with DAS\HHT vehicles. Does not support kline communication. Need to be specially setup on any diag sw installation.

SDConnect C4– 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. As for China clones, SDconnect has the best PCB design, the winner.

Stardiagnos Connect – workshop\robust tool. Very big and heavy. Most expensive. Similar to SDConnect because it is like PC+multiplexer in one housing .Has very specific setup as update blue ray disk has not installer but full HDD image with OS + user application. Complicated in installing additional software as you do not have direct assess to operating system.

MB SD Connect C4 requires to update VCI

We have a customer whose MB SD Connect C4 diagnostic system runs great but suddenly require an VCI upgrade.

He rename the VCI update file, but still failed to run Star diagnostic self test (Error screenshot attached)
