Hi.
I want to tune my 99 euro A6 2.7T tiptronic, but i cant define the bin file. I read some where that it's possible to flash the A6 ECU with a S4 file and then use the Xdf files already made.
So my question is, what file should I flash on to my ecu?
Current A6 ECU is 4B0907551G and engine is AJK.
I will upload bin file if necessary.
Don't even think about it. Best you can hope for on that ecu is the 551C euro S4 512kb file
