So the other day I installed VRSF catless dp's... At the most random times usually towards the end of a trip (it never fails lol) I get a catless dp code, which is to be expected.. But what I don't understand is the CDA7 error code that ALWAYS comes alongside the two catless errors.. The cda7 is some sort of reverse gear code.. Reverse works fine too so I have no idea what's going in... Any clue??

I was wondering if I should check the software.. I just bought it does this mean anything? Or would the software still be old i.e. Sitting on a shelf waiting to be sold with old software

So I took the laptop out to the car and read dme codes without any service lights and I got the cda7 code by itself.. What could this be?

Also is there anything I should be careful of when updating jb4 firmware or is it pretty straight forward
