CEL on newly installed jb4 on Lambo Urus

[Mata]

Its been probably 5 years since i’ve posted in this forum. Hopefully this is the correct place to ask this question

i just purchased and installed a jb4 on a Lamborghini urus, i double checked all my connections, everything is good, opted for the bluetooth connector and everything works fine, with the exception a CEL that i can not get rid of, my autel scanner reads ‘p2b7b’ and my jb4 app reads p83b4. (Only one code shown)
The check engine light turns on as soon as i turn the engine on. I try clearing it on the app and sometimes the light stays off only until i turn the engine on for a 2nd time after clearing the code.

I already sent an email to customer service, but hoping someone can relate to this issue and has some feedback
thanks for your advice

I am getting a hit on the fault being a EVAP code so potentially one of the front two connections are not in the right place. I have circled them below. For further help rather email me at [email protected]
