As above.

Using v11.11.3

Went ahead and fitted the Audi BT module 8P0 862 335 AA in preparation for my rnse retrofit. Works perfectly with the concert headunit, makes calls, receives perfectly etc.

I got the unit from Germany so the language it displays in the DIS is obviously in German. I want to change this to English so I went in to Module 77 - Telephone and opened up coding and changed the relevant number to English UK

But on changing the language to english and I press Do It an error comes up

Error 31 - Request out of range and the coding doesnt get saved.

Any ideas? I think the below coding is correct but obviously not the German and the final coding should be 0001222
