Must be difference in applications gremlin? i have only worked with the eeprom on vr6 applications not on allroad.
ME7.1.1 can and must be different.
For example. 4Z0907551 N/P/R/S boxes (2-nd generation) for 2.7T А6/Allroad have slightly different HW design compared to 1-st generation D/E/H/F/K/L/M boxes.
CPU content differs, use ST95P08 eeprom instead 95040, etc...
Me7.1.1 VR6/V6 ECU also differs from both generations turbo-ECUs
