We replaced the mechatronics in a 2014 vw passat cc sport with those from an 08 vw jetta Wolfsburg edition. Replacing part number 02E927770AL with 02E927770AD. I'm looking for guidance on updating maybe the software I don't know what I need to do......
The error code im getting is 65535 and the vehicle runs and drives until you get to 2nd and then seems to go into limp mode

The answer is I don’t know. You asked your question in a forum dedicated to Volkswagen ID.3 and ID.4 — electric cars not Dino juice burners.

Now, if I have to guess, you need to code your car to use that part. Check out Ross-Tech: Home for things that can help you code your Passat.
