Hello Guys,
I have here an ECU from a german Audi A6 C5 4B0907551S AZA Engine Tiptronic
The ECU will be installed in an A6 C5 with manual gearbox.
Which data fits here ? M-Box ? D-Box ? I can't find anything clear about the search.

Thank you for your help.

Greetings

any file marked 7.1.1 is cross flashable

Note that you should back up your immo just in case and be prepared to either rewrite/fix it or disable immo entirely.

Note that there are also some of these images that cause ecu bricks on read.

Hello, sorry for my late answer.
that means I can only flash files for ME7.1.1 on the 4b0907511S ?

The 4B0907551S is ME7.1, not ME7.1.1
