Some guy from the D2 found an ISO image for the A3 model, so I decided to go further and collect CDs for all Audi cars equipped with MIB2 High. Manuals were rereleased every 6 months in Europe but were never available in the US. ETKA doesn’t have part numbers too. I clearly see a pattern in the numbers but didn’t find half of them (yet). At the moment, I was able to download images for eight models and reuploaded them to MEGA folder.

The menu item should be activated in MIB2 coding (it was active and empty by default, but I disabled it previously):

Byte 19 Bit 0 — Owners manual

UltraISO is not necessary. Just extract the contents to the root of a flash drive or SD card. MIB2 recognizes drives formatted in FAT32 and NTFS.
