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-C3-C4-C5-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.

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.

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;

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.
