Xentry Passthru Coding

[Ling Baus]

2Xentry Diagnostics definition

Xentry Diagnostics is the complete diagnosis system that is used to troubleshoot Mercedes-Benz car problems and is the official Mercedes-Benz dealer software.

1). Different functionsXentry Passthru has nearly the complete diagnostic scope:quick testbasic diagnosisflashing & coding control unitsreading/deleting fault memoryguided and functional diagnosis, DAS4 serviceswith the exception of technical restrictions due to the Pass Thru devices:Only single-channel quick test and functional diagnosis (therefore longer runtime)Basic diagnosis only in XENTRY DiagnosticsKey programming and DAS4 services only in XENTRY Diagnosis

Technically yes, but it is artificially restricted according to the StartKey you are assigned based off of your HWID number given to Daimler, which in the US is restricted to emissions-related control modules before MY 2018.

This is pass thru version is there a other version for diagnose for pass thru device???so 1 dvd diagnose other dvd for programming?only 1 dvd mate. Sdflash folder for programming is include in it.the using of xentry passthru version is like the xentry open shell version only it is using passthru devices.

If you own a Mercedes-Benz and are looking to do your own repairs you may have heard about Mercedes Star Diagnostic (SD) scanners C3 and C4. In this article, we discuss the advantages of Mercedes Star Diagnostic scanner including things that you need to keep in mind before you buy a MB Star Diagnostic scanner. A list of top alternative scanners to Star Diagnostic is included as well. Note that this article is not written to approve or sell any of the scanners mentioned here including Star Diagnostic Scanner. We share our experience and research of diagnostic scanners and hope to help you the Mercedes-Benz owner who are looking to perform your own MB repairs and diagnostics.

Mercedes-Benz Scanner MB-Star Diagnostic allows you to read and erase fault codes from any control unit in your Mercedes-Benz. With Star Diagnostic scanner you can read the actual configurations in each system, stream real time sensor data, activate sensors and perform SCN online, SCN offline coding and programming.

This scanner is used by the dealer and it allow you to access and troubleshoot any system or control system in your Mercedes-Benz. Activate any sensor in the car, perform initiation test, stream live sensor data and also read and clear fault codes. If you own a shop who focuses on Mercedes-Benz cars then this is a must for you. Get it via official channels so that you can perform online SCN coding. All MB SD control units are accessible, like engine ECU, ABS, Airbags, SRS, Aircon, Immobilizer, Keyless Entry and the rest of 40+ control units used in MB cars. You can Read / Delete Faults, Live Data, perform sensor actuation, read current configuration, initialaztion and a lot more.

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.

What does it mean MARRYING a VIRGIN ECU and EIS? The ME (ECU=Engine Control Unit) and EIS (Electronic Ignition System) control module are electronically permanently married to each other after 40 engine starts. There is no factory procedure to undo this. This means that a used engine EIS or DAS control unit cannot be used on another vehicle. A new control unit can be installed for testing provided the 40 engine starts are not exceeded. Note that the new control unit must be variant coded before it can be used. If the 40 engine start cycles are not completed successfully resetting the counter to 0 (removing the version coding) is possible if you disconnect the power from the ECU for at least 45 minutes.

What is Xentry? New software released by Benz Company after 04/2009 by diagnosis new cars.

What is Smart TAN Code? It openes special function in DAS program with Smart cars 450/451/452/454 Developer model: Mercedes-Benz engineer mode, remove limitations and open more functions.

As this car is based on the W204, there were provisions for everything related to the manual transmission. The firewall insulation had a precut section for the manual pedal box, there were 2 holes in the firewall for clutch hydraulics, there were extra holes drilled and tapped in the unibody for varying lengths of transmissions, literally everything was bolt in.

As of right now the car starts as long as I have the automatic shifter mechanism plugged in, and goes through all of the gears with no screeching from the computers. I'm currently waiting for the driveshaft to arrive as I forgot to purchase it from the donor C300, and I'm also waiting for my J2534 device to attempt to start coding the computers from automatic to manual.

I'm mainly starting this thread so people have a different google result other than "can't be done too many computers" or "can be done but will cost a bajillion dollars" when they want to swap their W/X204. Once I get it coded I will list out the modules and addresses that need changed and a final parts list.

Xentry passthru and a Chinese J2534 device. You can buy clones of Mercedes C3/C4 multiplexers on ebay to use with DAS and the full Xentry suite, but I was advised that for just coding modules passthru is all that is needed. My J2534 should be here today, so I'll have a better idea of how well this will work out later.

So far the hardest part of this has been sifting through the various forums looking for the right combination of programs to let me edit modules. I finally got access to the developer options in DAS for the ME97 and it allowed me to change my transmission type from NAG 2 to NSG here:

I can now start the car with all automatic transmission components unplugged. I still need to code out the central gateway module (or SAM) to get rid of the PRND in the cluster, but I think I need a better cable than the one I have now for that as it won't read the module version. After that it's just putting all of the trim back together in the interior and that's it.

I used DAS to change the implicit coding of the ME97(me97.cbf) from automatic to manual (in the post above), and vediamo to change the implicit coding for the central gateway (cgw212.cbf) to change "423_427_automatikgetriebe" from available to not available to get rid of the prnd in the cluster. Used vediamo to program the front SAM (samf_172.cbf) RG_EN from nein to ja in VCD_Parameter_Rueckwaertsgangerkennung for reverse lights.

Thank you! Yeah it really was surprisingly simple, even though it did take me a while to find what I actually needed to do to code the modules. When you have the right tools Mercedes actually makes it easy to tinker.

Swapped in a color instrument cluster from a 2014 GLK and the dang shift indicator is back. None of my auto > manual coding changed, so I think this is just part of the software in this cluster. I'll have to look in to how I might be able to change it.

To swap a used cluster you'll need to "virginize" it by having the mileage set to 0. I paid for this from a website called MBTools, there are ways to unlock the cluster with seedkey calculators but I never could get one to work.

iammclovin804 - this is really cool how how you made this happen and dispelled the "it can't be done" mindset. But since new cars are so computerized now, not shocked that a different year cluster behaves differently, but I am confident you will figure it out.

Would you say the swap is worth the effort? I'd imagine your MPG went down somewhat, but by how much?

You're a scholar and a gentleman for tagging the part numbers and tools needed to code this. Nice work since it looks like clean swap!
