Firmware update on my Audi A4 B8...

[dave chante pas]

Hi,

I am actually looking to update the FW of my A4 B8 (end of September 2009 so assume MY 2010 )
I own a MMi 3G (the one with Carto on DVD and 2 SD card ports...and so no HDD).

Actual version is:



I copied K0257 update files on an SD card, put it in SD1 port and try to launch the Fw update, I get this screen:

If I try to go ahead, I then get this error (or warning in fact) screen:



Translation:

WARNING: The software can became inconsistent


...using the scroll button, on the bottom I can proceed with update if I'd like:




So, is K0257 the compatible version for my car??
Can I go ahead without any problem??

Thanks in advance for your support,

BR
