ABY vs AAN ecu

**~Delta** · 16 October 2006, 18:20

As far as I can tell, the ABY / AAN ECU's are interchangeable, Immo codes may be an issue though.

My S4 now has an ABY ecu thanks to a certain company in the Chester area beginning with Q!!

Works fine though! I remember Mihnea telling me that they were just about identical!

thanks for now. on some other forum i get infos that i have to look for ecus from s4/s6 without avtomatic gearbox and immo

so any ideas whitch letter should be at the end of ecus audi nummber? i guess AA or A is fine?
