ZTAudi  Audi A6 C7 3,0BiTDi TCU pre-dieselgate software.
Hello!

My car is A6 2014 3,0BiTdi 230kw CGQB with ZF 8HP-55AF

Can I use new(dieselgate) TCU software with old(pre-dieselgate) ECU software,or there some trick from factory?

I have today ECU software 4G0907589E 0003 and if I will upgrade TCU to 4G0 997 749 C 1001 ,is this software will work together with old ECU software?

You will get software incompatibility error if it doesn`t work. So just flash it and see how it goes
