I'm looking for some assistance to understand the complexities and the dataset/coding needs required to changing out the 32-pin KESSY module (3Q0959435C) from my 2017 MK7 Golf R to the MK7.5 Golf R KESSY module (3Q0959435L). I've attempted this retrofit with a local dealer and with a local tuner (skilled with ODIS) with both were unable to get past ODIS message stating that the module is not intended for chassis and was not able to be adapted. Neither had any success or knowledge of anyway to get around the message. My next step is to go back to the dealer with the 3Q0959435G module (as per a user on ross-tech suggested) and see if we can get that one to work. Otherwise, the master tech at my local dealer said that because of the way ODIS has been centralized at VWoA corporate, he can't get past the message from ODIS identifying the 435L module not associated with the build certificate. Any incite or suggestions would be appreciated. Thanks! I understand that this modification may no longer be possible due to ODIS hurdles.
