CBB ECU validation file needed - kenza750 - 17-09-2026
All,
I was looking for a solution to solve SWT test condition check failed error messages in my G31 LCI 530d.
Figured out I should try to revalidate the impacted ECU's using the CBB request file.
Someone here on the forum who has access to DCSNet CBB to generate the validation file?

I tried to fetch the request file from i5тд but it requires me to connect a power supply. Will do it this evening at home

Didn't think of it
Added the file to the first post.

Thnx a lot Blax123.
Couldn't wait so I just loaded the response file.
All certificates seems OK according to ё5у5 (screenshot).
I cleared all errors in i5тд and I will check tomorrow or the day after whether the SWT errors are definitely gone.
I will report back (and hopefully other users in the future can benefit)

What was the respective certificate status before loading the CBB response?

I did not check. According to some sources, reloading the validation file could initiate a full sync between the modules.
This morning I did a full vehicle test and the SWT errors did not appear. usually these appear almost directly after deleting the fault memory.
I will check again tomorrow but as of now, I seems like the problem is resolved by loading the response file.

unfortunately, the SWT errors came back after 1-2 days. Validation of the ECU's did not solve the issue.
