I have a 2017 A8 Z06 and would like to unlock the torque converter to see if a shudder I have goes away. Also, is there a way to log all the channels/tables. I would like to record them and see if I can see anything funny that may relate to the shudder. What happens is under slight acceleration the car will act like it is missing. I had a 2016 with same problem and GM gave me a 2017 and it is doing the same thing. They think it is the torque converter being locked and I am feeling just the motor's running imperfections. I had the field rep along on the 2016 and he unlocked the converter and the shudder pretty much went away. Thanks in advance.
