MB Star C3 092015 Xentry cannot work on W204

MB Star C3 Star diagnostic system failed to work on Mercedes W204? Here is the customer solution. You are at your risk!


I have DELL D630 with Xentry 09/2015 and Mercedes Benz Star diagnosis C3 multiplexer. I have connected many cars (W202, W203, W210, W211, W245, etc) and there is no problem with connection – everything is working like a charm. Some days ago, I have bought W204 C280 from 2007. After I choose model, engine and transmission, and I go to diagnostic I see this:

“The diagnosis application is being started…”

and few seconds later this:

“Initialization of the multiplexer has failed”


My Mux is not compatible with W204? I searched few hours without success.

Customer solution:
W204 and X204 is the last Mercedes models which working without some special modifications.
You can try:

First try in toolkit.ini delete line skipcomports=all and set line usecomport=2 then you will see in SDconnect toolkit PartD on display after mux connection.

First save your original file for sure.

Try look into C:\Userdata\Config\Xentry\driver – slave.ini and set there com port which you have used for PartD.


There was no change because I didn’t restarted system. After restart work perfect.

Your solution work perfectly! Probem solved. Everything is working like a charm.

Youobd2.com solution:

If you need to deal with newer Mercedes models, better go for MB SD Connect C4 or MB SD C5 diagnostic system.

Will you do some maintenance work for your car? Or, are you willing to do some maintenance work for your car?

In early 2015, Nexiq Technologies discontinued the “tried and true” original Nexiq USB Link. This adapter had been around for around 7 years, and was wildly popular. One of the main reasons that the Nexuq USB Link became so popular was because of their distribution. Nexiq is 100% owned by Snap On, so between the large marketing spends, industry trade shows, and Snap On tool trucks, Nexiq has an unmatched distribution network. The other large source of their distribution comes from formal truck dealerships, as Nexiq is the recommended product for various truck manufacturers such as International, Freightliner, and many others.


The USB-Link 2, the next generation vehicle interface from NEXIQ Technologies, has arrived. Dependable and rugged, the new USB-Link 2 is five times faster than its predecessor. It has sixteen times more random access memory than the old USB-Link, and it supports heavier bus loads on simultaneous channels.

It also includes a new Bluetooth* module with an enhanced data rate to support wireless communication (500 b/s J1939). For even more reliability, we've upgraded the USB connector to a more robust, automotive grade connector with a latching mechanism. The USB-Link 2 is compatible with a wide range of OEM software applications.

·  Latching USB Cable (Part # 404032)

·  6 and 9 pin Deutsch Adapter (Part # 493148)

·  storage case



·  Class 1 Bluetooth provides up to 100 feet of wireless freedom.

·  Flexible configuration supports wired or wireless connectivity.

·  Compatible with applications that diagnose engines, transmissions, ABS, instrument panels and more.

·  Reduce reprogramming times with direct USB connection.

·  Mixed fleet capabilities with broad protocol support.

·  Quick access to vehicle data for maintenance or management reports.

·  Quickly attaches to vehicle's diagnostic connector.

·  No messy cables to untangle or get in the way with Bluetooth.

·  Easy portability increases flexibility.

·  May be used with desktop PC or laptop.
