Similarity:

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

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

Difference:

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.

All Benz diagnostic and programming Benz Ecom VS SD C4

New Arrival: Benz Ecom diagnostic and programming tool for newest Benz models. It comes with Dongle and software in the hard disk, activation via remote assistance. Works with newest Benz models instead of old models like MB SD C4.

1.Ecom
Support diagnostic software Xentry, engineering software Vediamo and super DTS Monaco,  it has a than higher access right than SDC4.

Ecom supports the CAN/DoIP protocol, which can be used to diagnose and programming (brushing & writing) for the new car audio and video entertainment systems.

The Mercedes-Benz engineering database of diagnosis / coding / retrofit /flashings is using the Xentry database, so the Mercedes-Benz engineering version depends on the version of Xentry, as long as the database is new, the V4.00 version can be used on new models. compact3 can be used.
SDC4 does not support ODX documents. The latest V5.00 uses eCom to support ODX files. It is recommended to use Ecom, with DoIP function, the speed is faster and more stable.

2.SD C4
Support the diagnostic software Xentry, DAS software diagnostics, engineering Vediamo,  super DTS Monaco, Xentry and DAS Developer mode etc.

Common Name: Developing Data Engineering Edition After 2010
Version, added a lot of functional restrictions. So everyone will encounter the problem that the vehicle version is too new to enter
the control unit, or entering the control unit and cannot make any special modifications. For example: W204 /212 2012
The instrument is needed to modify the regional language configuration or open other convenient functions. With the increasing number of new car with DoIP protocol, the mb star SDC4 has slowly failed to meet market demand.

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.
