Here is a tutorial of how to do it: use MB SD Connect C4 mux to enable tank info & L/100KM into KM/L mercedes W211 (W203) (w221) and more

In DAS Developer mode :
Kombiinstrument -> Diagnose nach Werkangabe -> Steuergerate-Anpassungen ->
Steuergerate-Anpassungen (Variantencoderierung) -> Variantkodierung Werkeinstellungen ->

In the menu that shows , you scroll down untill you read the line : Tankinfo im Reichweitebild
enable this option
now you have tankinfo in the screen that otherwise only showed range

If you allso wanna adjust the way fuel consumtion is showed
you scroll a little more down untill you read the line : Verbrauchanzeige km
you can change it from L/100km into km/l

Scroll down and confirm Coding by pressingF3

if you watch your Instrument Cluster , you notice that scrolling through the menu , nothing changed .

For this , the “Kombiinstrument” needs a reboot.
to do this in Developer mode we go back by hitting F1 -> 3 times

How to Choose good SD C4 Star Diagnosis SDConnect MB Star C4

MHHAuto Mb Star Connect C4 Mercedes Benz Star Diagnosis SD Connect C4 Experience Sharing

There are so many kinds Auto key Programmer MB Star C4 SD Connect Multiplexer in the market, how to choose a good Star Diagnosis SD Connect Multiplexer? Below eobdtool.com share a Star Diagnostic SD Connect MB Star C4 Mux identify guide as following. This is sharing from MHHAuto forum, great Mercedes Star diagnostic SDconnect SD C4 tools experience sharing.

MHHAuto Thread: SD Connect C4 — avoiding garbage

I’m in the market for an SD connect C4 on www.cnautotool.com mercedes benz Star Diagnostic Tool and have been trying to spend my time doing some homework to avoid getting a garbage unit. I certainly can understand what a lot of people have been saying about the widely varying quality that’s out there. I am a EE and PCB designer, so I’m trying to make use of that knowledge to select the best unit that I can.

To that end, I’m going to share what info I’ve collected so far, and when I finally end up buying whatever unit I do, I’m going to do a full teardown on it and post the results here.

As another matter, I’ll openly post details on who I buy the unit from and impressions after receiving it.

Near as I can tell right now, there appear to be about 4 “factories” that make different units.

One thing I’ve been asking all of the sellers for (and I would encourage others to do the same) is photos of the actual MB Star C4 SD Connect unit (including PCBs) with a unique identifier in the photo to prove that the unit they say they are going to send me is the actual one they send me. Of course, some sellers immediately bail at this, but then you know who to avoid ahead of time.

In general, a lot of the components used in a Star diagnostic tool SD C4 Multiplexer are getting quite long in the tooth. Many of the parts are approaching 20 years of age. Thus, you stand a fair risk of getting pulls (used parts) and/or remarked parts on these.

In following posts, I’ll provide photos of what I can discern as differences between the MB Star Diagnostic SD Connect C4 units along with some commentary about whatever info I can provide at this point.

to, I’ve outlined some things I feel are important to note. They have a set of 4 analog switches on the PCB. In this photo, they are ADG426 from Analog Devices. I’ve seen some clones that use DG526CY from Harris/Intersil. The DG526CY, besides being completely obsolete, has an typical RDSON of 270 ohms vs 80 for the Analog Devices part. It also has a -55dB isolation vs -75dB for the AD part. In short, the AD part is just a much better mux. So with that said, I would insist on any unit I’m interested in using those.

A second thing you’ll notice is the use of can crystals where 4 pin variants were intended. This is just sloppy and cheap. There may also be issue with loading (and ultimately clock stability) depending on whether they matched the loading caps to the substituted crystal or not.

I haven’t had a set of photos high res enough to look at the rest of the actives in detail yet, as most sellers don’t seem to post them.

There’s also an issue pointed out on the bottom of the board where one of the (what appears to be) MOSFETs in (what appears to be a) D2 PAK looks like it was hand soldered. Again, no good.

This next photo is of the relay Star Diagnosis SD Connect PCB— I think one of the MHH members posted this from an original SDC4.

Why MB Star C3 Xentry cannot work on W205 recent Mercedes

August 24, 2017 by wp-admin

User puzzles:

I have installed Xentry 9.2014 in Benz MB STAR C3 multiplexer. It works well so far. Now, I need to make diagnosis on mercedes w205 year 12/2014 but It can not communicate with the car. C3 don’t work in all recent cars in xentry but in DAS is ok.

Experienced users’ suggestion:

C3 has many limitation regarding latest vehicles in Xentry.
It can’t diagnose it e.g w205, w212, w222, w906, smart 453 etc.

its glory is already passed unless you deal only with vehicles in DAS.
you have to change to MB SD Compact C4
C4’s support also officially has been stop since 12-2015.

It is no different even you change folder.
it is different protocol with recent vehicles.

For your w205 (nice car) you can use one of this :
1.sd connect c4
2.Mercedes Benz C5

Both good at all new Mercedes Benz models,W222, W221, W212, W203, 211,W 204,W207, W212, GL166, B 246, CLS 218, SLK172 and Smart405, 451, 452, 454

Besides the MB Star diagnosis software c3 and c4 own, sdconnect c4/c5 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.

I have successfully communicated wit my w205 AMG using a MB SD C4 connect all controllers accessed
