After my research I think I was searching in vain.
The APP and the ARZ are said to have never been available with an automatic transmission.
M-m-m.... There are at least two firmware variants.
ARZ engine with automatic transmission -> firmware 06A906032AT, Euro3, coding 05530
USDM version of 1.8T Engine AWD with AT -> firmware 06A906032CM, LEV, coding 06530 or 06430
Both with narrow O2S without VVT and use flash memory 29F400.
