Help. We have replaced the mechatronics in a 2014 Volkswagen Passat CC Sport with those from an 08 Volkswagen Jetta Wolfsburg Edition essentially we changed part number 02E927770AL with 02E927770AD. I'm receiving an error code 65535 and I'm really unsure where to go from here I believe I need to update the software version but I need some guidance on how to do that please help the car runs and drives but it goes into limp mode when I get to second gear
