W204 - AMG Menu

admin — Fri, 12 Jun 2026 19:10:48 +0000

Preparation: Connect to IC_204 in Vediamo. Go to ECU Identification and write down your Software Block #0 (e.g., 2049021203). You need this number for the Seed/Key calculator. You can use SeedCalc or UnlockECU for this. I personally used the UnlockECU Web version.

STEP 1: Read Your Original Bytes (Do this BEFORE unlocking!) Do not skip this. If you unlock the ECU first, you will hit a 5-second timeout and get locked out while trying to read.

Open the manual command input (F12).
Send UDS command: 23 14 10 00 01 D0 08 (This reads the AMG menu line).
You will get a response like: 63 FF FF FF FF FF FF FF FF
Open Notepad. Copy those 8 bytes, change the first byte to FC, and build your write command. It should look like this:
3D 14 10 00 01 D0 08 FC FF FF FF FF FF FF FF

(Optional: If you have a diesel/CNG, read line 000260 right now too: 23 14 10 00 02 60 0A. Copy the 10 bytes, change the last two to 30 60 for diesel pre-heat fix, or 30 82
for CNG fix, and prep your second write command in Notepad).

STEP 2: The Security Unlock Speed Run Now you unlock the cluster. Have your Notepad open and your

Now you unlock the cluster.

Level 9: Send 27 09. You'll get an 8-byte seed. Put it in UnlockECU (Level 9) to get the key. Send 27 0A . If you get 67 0A, you are good.

Level 0D (Level 13): Send 27 0D. Get the new seed, put it in UnlockECU (Level 13) to get the key. Send 27 0E .

WRITE FAST: The second you get the 67 0E success response, the 5-second timer starts. Immediately paste your command from Notepad and hit send.

If the ECU responds with 7D 14 10 00 01 D0 08, the flash was successful!

Send the 11 01 command and it will reset your cluster. The cluster will click, go black, and reboot with the AMG logo and menus.
Check if the preheat diesel lamp is turned on when ignition is in 2nd position.

Updating Command Firmware

admin — Fri, 12 Jun 2026 19:01:20 +0000

I just wanted to make a guide for using SDFlash to update NTG head unit as I found it difficult when searching online how to perform this job.
To find out what disc you require and what the latest software is you need to get a copy of the SDFlash folders these can be found online if you look hard enough.
I am performing this on a NTG 4.7 head unit.
So the first thing you need to find is your hardware number I found mine using XENTRY as you can see below.

chris966 · 21.01.2024 at 19:05

Once you have this you need to check the in all the SDFlash version. CDI files for your hardware number in the PKW folder of the SDFlash as shown below.
These are in SDFlash version / Release / PKW:

chris966 · 21.01.2024 at 19:05

So we know now my hardware number is 2129017506.
So we need to search that number in the CDI files I use "Notepad+".

chris966 · 21.01.2024 at 19:05

As you can see my hardware number was found in the CDI File named 1668274700-0001.CDI
Which means my Telematics disc needed would be A1668274700.
If you then scroll to the left it will tell you which CFF is needed for Flash.

CFF Name = Blue
Version = Red

AMG Menu W211/W219

admin — Thu, 11 Jun 2026 22:27:14 +0000

We are interested in line 0210, it comes in 2 types: XX XX 19 00 or XX XX 11 00(FF), each is activated differently.
In the original AMG, line 0210 contains the code XX XX FF FF, but this does not work on normal dashboards; there are some glitches, and sometimes the tachometer does not work.
In order for everything to work correctly, you need to:
For instruments with line XX XX 19 00 you need to change

XX XX 39 00 AMG menu
XX XX 39 01 AMG menu + oil temperature
XX XX 39 03 AMG menu + oil temperature + battery voltage

For instruments with line XX XX 11 00(FF) you need to change

XX XX 31 FF AMG menu + oil temperature + battery voltage



For W211/W219:

1.On offset 0210: "XX XX 19 00" must change to
     A. "XX XX 39 00" for just AMG menu
     B. "XX XX 39 01" for AMG menu + Oil temperature
     C. "XX XX 39 03" for AMG menu + Oil temperature + Battery voltage
	 D. "XX XX F9 03" for AMG menu + Oil temperature + Battery voltage

2.On offset 0210: "XX XX 11 00" must change to
     A. "XX XX 31 FF" for AMG menu + Oil temperature + Battery voltage

3.The original AMG IC have code “XX XX FF FF” on offset 0210 (Full AMG options)

If the message persists, repeat the steps and ensure the coding was properly applied.

Important Notes

Disabling safety features may reduce vehicle safety – Always consult a professional before making coding changes.
Ensure that your DTS Monaco software is updated to avoid compatibility issues.
Some Mercedes-Benz models may have additional dependencies, so proper diagnostics should be performed before making changes.
