(Solved) SD connect C4 NOT Connected via LAN or WIFI

Here are optional solutions for those with a Sd connect C4 but cannot be connected via LAN (or wifi).
Operation system: Window 7
Static IP:
Battery: the 6 batteries are installed, fully charged

Error message:
when I connect it to the MUX (the 6 batteries are installed) it tries to connect but it gives up after a minute or two and I have a yellow triangle over the network icon in the taskbar.
The display on the MUX shows that its number is 00, it also displays a cable icon and a countdown timer and the message “Device not in use”
SD connect C4 NOT Connected via LAN or WIFI

The display doesn’t show the wifi option, only the cable icon.
When I start SDConnect Administration Toolkit it says the MUX is not cable accessible.

Possible solutions from users:

Option 1: LAN adapter
Open it and check the LAN adapter soldering if it gone loose

SDConnect relies on broadcasts/multicasts (like the DHCP protocol) to discover SDConnect devices.  They can be con completely different subnets and be “detected” but you cannot interrogate or configure them until you get their IP addresses configured for basic management setup.

Option 2: Toolkit
For Connection you´ll need the Toolkit.
WLAN is not seen until configured, if you reseted the SDConnect you´ll need to reconfigure it with the Toolkit.

Option 3: Battery
You may try forcing your NIC in your laptop to 100Mb/Full Duplex, as many will default and negotiate to 1Gb/s, which I don’t believe some of the SDConnects talk over too well.

Also, FWIW, I have been getting an error 750 when trying to communicate to the SDConnect recently.  The connection seems very unstable. I have only used a direct Ethernet connection.  I have not investigated it very much, but I have resorted to the C3 for right now, which has never failed with 1.2012.
I reset it back to factory settings as well.  I have not had an opportunity to investigate it to any extent, so I am unsure what the problem may be, but SD NetContol is stating a Network Error to the SD Connect. It is all connected via CAT6 and no WiFi.
It is best practice to remove the batteries form the SDConnect when not changing firmware or leave them in there?  I have quality rechargeable batteries I use and typically leave them in when changing firmware, but I have left them in for a longer period.  When I removed the first set, the batteries clearly leaked but didn’t appear to damage the SDConnect and I throughly cleaned it and it has worked since them.

How to Slove MB SD C4 Cannot Access OBD2 Port

​When using china clone mb sd connect compact 4 Multiplexer, it could not link to the car computer, MB SD Connect C4 offered a message, saying like “check cable connection / turn ignition on”. Then tried again, clone SDconnect compact 4 multiplexer cannot access OBD2 port

According to customer’s feedback that he failed to access to the diagnostic OBD port when tried to use sd connect c4 read errors code from Benz SRS system. The system prompted an error message “check cable connection/turn ignition on”.
Possible Reason:

The error lies on the SD Connect C4’s battery.
​Solution from

1) Check and record your MB SD Connect C4 multiplexer battery
2) Hook up a digital multimeter to set it to the direct current
3) Get two t-pins and plug them into the OBD socket at PIN 5 and PIN17 position
4) Put your positive lead to PIN16 and negative lead to PIN5.
5) Write down the voltage on the digital multimeter
6) Check if the voltage you from PIN16 and PIN 5 is same in step 1.
7) Find the light green wire with a blue tracer band of PIN10 of the OBDII connector.

Clone Xentry Connect C5- Good & Bad Things

I bought “Original Clone Xentry Connect C5” from China’s retail store in 2017/12.

Good thing:

1. Unlike bad products of mercedes diagnostic tool C5 type C4 motherboard, texture is good
2. DoIP specification

Bad thing:

1. Because it is VM system + 32bit, the reaction is slow (SSD though …)
2. Vediamo can be used, but feeling like driving with DELL D 630 (unsuitable)
3. The DTS Monaco software is installed but the connection with the vehicle is NG (currently retail stores and manufacturer engineers are thinking about how to fix it)
4. Passwords are applied to each drive, making it hard to customize
5. Retail shops and manufacturer engineers lack knowledge (take time to support)

My thoughts

I think purchasing this product is still early.

There are too many trouble elements.

I’ll report it when the situation changes.

What I currently use (stable and comfortable)

New car: eCom (64 bit)
Normal: Clone SDConnect C4 (64 bit)
Old car: Star C3

Best regards

My findings MB Variant coding tweaks & throttle delay


[[I am copying this post from the one I made on CnAutotool as well, I figure both forums should see it, especially considering MrScott belongs to this one!]] This post assumes you have some knowledge of the software used. I’m not entirely comfortable making a full walk-through for beginners, as this is potentially risky.

After spending quite some time tinkering with and learning about Mercedes Benz Diagnostic Tool, I believe I’ve almost completely solved my issues with throttle lag on my car. Since owning the car I’ve noticed that depending on how the car is driven, like through heavy traffic or on country roads, the throttle response to the gas pedal does not seem to stay consistent. For example, if I start off driving the car in stop and go traffic, the pedal seems to become “lazy”; next time I mash on the gas, there’s a very noticeable delay in throttle input and sometimes the car doesn’t shift down when it should, either in C or S mode. It was quite annoying, and on a few occasions, kind of risky. Aside from that there’d be a very noticeable difference in the way the car performed on a day to day basis, sometimes it felt sluggish, and other times it felt pretty quick. I really didn’t like how it was unpredictable.

This is discussed in a threads like this, and it appears that ECU adaptations are the cause for this. I’m sure the adaptations would be effective in some cases, but where I live and how I drive, the adaptation process seems to have a difficult time calibrating the throttle response, and the result has been pretty undesirable to me. It seems others have the same issue, and have tried solving it doing the simple TCU reset. This reset does work, very temporarily. Every time I tried it, it’d help for a few drives but then it’d revert to sluggishness. I went over 10,000km after pulling the car battery and doing the TCU reset to see if the car needed a long time to “learn”, and it did improve, but the inconsistency/unpredictability of the throttle input, and delay, still remained an issue.

I’m very glad to have spent the money getting a diagnostic multiplexer, as it’s allowed me to learn quite a lot about how these cars operate. On top of that, I’ve done a bunch of tweaking to get things to how I’d like. If you have access to one, or know someone who does, the following tweaks have solved these problems for me. This could likely be accomplished in Xentry rather than Vediamo, but I was unable to get access to the necessary settings through Xentry myself. I Please note, I have no idea the effect this will have on warranty, as my car is completely out of any warranty..

MrScott52, a very helpful member of Benzworld posted a youtube guide on how to enable a few parameters to increase responsiveness of a diesel variant in an earlier version of DAS; these tweaks seem to make a difference with my 2.5L V6 M272 w204 as well. (I’ll link the video in a following reply.)

Attached below are the necessary parameter changes for the ME 9.7 ECU in Vediamo, which solved my issues with throttle delay (many listed in MrScott52’s video), and here are the descriptions of each:

#1 (Lastschlagdaempfung) This is the most important one. This parameter seems to be the main culprit for the inconsistent feeling throttle response and sluggishness, and I believe it causes the wonky throttle bodyadaptations which I find so awful. Disabling it has removed most, if not all delay in throttle input. It is referred to as “load-reversal damping” in Vediamo (german), but it is the “Throttle Change Damping” parameter in Xentry. I changed this parameter about a month after the others, and it definitely had the most significant impact on throttle response, and now the throttle is very consistent in performance. I believe this parameter is more directly related to the actual throttle body than the gas pedal, unlike the next parameter.

#2 (Pedalkennlinie) This is the pedal curve parameter. My car had KLD4 as default. You can play with this, and possibly leave it at KLD4. However, I changed it to KLD2. From what I understand, KLD2 is meant for cars with a manual transmission, and as such, I’d expect the pedal curve to be the most “natural” feeling to the driver. In contrast, I believe KLD4 is more responsive, but “jumpier” (more erratic in terms of throttle input). Combining KLD4 with disabling the throttle change damping parameter may be undesirable in terms of comfort/consistency.

#3 (Momentenbegrenzung) This is the torque limit parameter. The main effect I’ve observed from disabling this is that the car doesn’t reduce throttle/torque as much while cornering anymore, and the car seems to accelerate slightly faster from a standstill than before. May not be necessary to fix throttle delay, but I find it favourable.

#4 (Momentenerhoehung Getriebe) This parameter is supplementary to #3 . Like MrScott describes in his video, it allows the engine ECU to monitor torque output and send it to the transmission, but keeps it within safe/comfortable limits. I find this parameter to improve gear shifts very slightly; torque input and acceleration remains very steady throughout gear shifts. I believe it very slightly improves acceleration, even compared to only having the torque limiter disabled. Do not change this to the GSG setting. Doing so resulted in some very uncomfortable shifting. I’m not sure if there’d be a long term effect on the gearbox here, so just don’t as a precaution. The Benz diagnostic tool highlighted in black is the default setting – the ECU is not allowed to increase torque to the gearbox depending on measurement.

With all these parameters changed, I have my car performing the way I’d like it to. It’s performance remains far more consistent, there’s significantly less throttle lag, and it does actually accelerate faster (I’ve measured), but only very slightly. Starting off in C mode on an incline also no longer feels like as much of a strain. Now, all of this being said, if you have the tools and such to do this yourself, or know someone who can, you do so at your own risk. I’ve driven over 10,000km already without any negative effects of this, but I just don’t want to be responsible if anything goes wrong. I can’t imagine anything would, though. If you are willing to do this yourself, please be aware that there are many ecu parameters that are difficult to understand, and modifying them at all could potentially cause irreversible damage. I do not recommend making adjustments to any other unknown parameters without thoroughly researching their function and/or purpose.

p.s the screenshots were taken in simulation mode, I didn’t think to screenshot anything while I was actually connected to my car. The highlighted values are still of course relevant.
