RE: Checksum error old ecu Audi 1.8 AVV egine
For me it recognizes it as 7.1.1, I once had so probably in a8 d3 also badly recognized, if you are sure that you have chosen a good protocol and read it well I can in both of these files try to disable lambde if you want.

I remember that in this a8 d3 I also read as me 7.5 but I did as 7.1.1 and wrote as I saved as 7.5.
