Any chance you forgot to disconnect the battery before install?

No sir battery was disconnected when I did install

UPDATE: i got the codes for a second time today, cleared them while driving and they have not came back, car runs great after clearing the codes. Same as the first time.

So, it keeps happening but you aren’t doing anything to solve it? Seems legit.

I have to agree with razorlab, your code keeps coming back even after clearing them. Perfect way to break your car ?

disconnect the Flex kit, clear the codes, and see if they come back.

I've had some crazy flexray errors when wiring stuff wrong.

^ See above for the best recommendation so far other than taking it to the dealer. You perform a wiring change to the BDC wiring and get codes that keep coming back...
