How to Save Coding to HU6

[Meru]

Do these instructions also apply to the 2021 NTG6 W447 model?

If you have the correct SMR-D file, this will work.

It works perfectly on W447.

Saving can be done on the right side under loading the coding file. Click save.

Unlocking EZS167 with the seed key is one of the options. Most projects have EZS Authentication and after coding a hard ECU reset is carried out automatically.

I can't seem to open HU6 to code the faders. From the EZS167 I can open the firewall with security access levels 1, 39 and 3B without any problems. I see another security level - 61, which I can't unlock with the "Transmit" button, the status says that the attempt failed (wrong key). In HU6, when I click the "Transmit" button in "Extended Start", it says security access denied.

Security access level 37 in BCMFA2 gives an error message (communication error) after pressing the "Transmit" button.
Same with security access level B in CONNECT907, failure (communication error).
Do you have any advice?

EZS167 file, I used one from the Xentry database. My Xentry release is from 2024.
If so, where can I get the new EZS167 file?

I also think the file is incorrect. I usually had issues unlocking when I used the wrong file. I tried a different set of files and after that everything worked. Try using a different HU6 file as well.

Thanks for your message. Can you point me to where I can get another set of files? Is the "DTS Monaco Projects Database" available here useful for me?
Sprinter W907 is the van I'm trying to code.

Here on AutoGMT admin R00TR0w posted a database for the Monaco project, try it. The official one from Xentry worked 50/50 for me.

I now have the Xentry 09.2024 files and they seem to work, no connectivity issues. BCMFA2 and EZS167 firewalls are disabled without issue, but HU6 still shows "Security access denied" after clicking "Transmit" in "Extended Start". EZS167 has a security access level of 61, which I can't disable.

From Connect907 I can't disable security level B due to failure (communication error).

So this is the new 2025 Sprinter, and the Xentry displays MBUX as DISPS2. There is no Connect907 or HU6 in the quick scan list. I went through the entire car and copied every file for every module that was on Xentry's quick scan list. If DISP2 is set to DTS, the option code list for this module is empty.
