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
The only way to reprogram to the latest update on the software is to take it to the dealer. The software from what I know is not available outside of the dealership. The Metronics computer from a 2008 may not work properly with a 2014 you would have to cross reference this at the dealer to see if it is compatible.
