What is Xentry DAS Diagnostics?

Xentry DAS (Diagnostic Assistance System) is the complete diagnosis system used to troubleshoot Mercedes-Benz car problems and is the official Mercedes-Benz dealer software. It can configure, reprogram, initialize new components, program, perform guided tests, and read or erase fault codes in any system, including AirMatic, AirBag, SRS, EIS, Transmission, ETS, BAS,  and all of the control modules. DAS Xentry software requires the C3 Multiplexer Star or C4 SD Connect hardware. The c3 multiplexer is an earlier model that the C4 SD Connect replaced. To operate Xentry, you will need a laptop with a serial port RS232 to connect the Multiplexer and run the Xentry software. The online market is flooded with pirated versions of the Xentry Diagnostic scanner, so be careful and avoid those hacked versions. Online merchants who may not be authorized resellers distribute the software and show you how to install Xentry, as you can see on this guide.

Individuals or businesses in the United States can purchase systems by contacting Mercedes-Benz USA LLC. Contact MBUSA, the official source, by visiting the STAR TekInfo website.

Be wise when you purchase a Xentry DAX Multiplexer, as there seem to be a lot of cloned versions on the market. Unfortunately, there isn’t a good way to know what is original. Buying DAS Xentry program Diagnostic Software for Mercedes Benz on Amazon at least adds an extra layer of protection in case there is an issue. We would not recommend buying from retailers that ship from China on eBay. Yes, you can return those units if there is a problem but you will have to pay return shipping and will not know if you are getting an original unit. We do not endorse any of these sellers or know if these are authentic versions.

What is Developer Mode Extension for DAS?

It was meant for the development and testing purposes of the onboard electronic systems. It will allow the user to change the configuration of the car. For example, you can change the ECU, program to use a different engine model, change the speed limit or torque settings, and more. Using Developer Mode without knowing precisely what you are doing can be dangerous.
