Hi all,

I'm very new to the JB4 system, I only heard about it a few weeks ago and here I am now with a new car (2013 N55 135i 6MT 51k miles RHD) and a jew Jb4 that I installed. Now I installed the Jb4 and it runs lovely car instantly feels better and I can tell it's working. I installed an ingen air intake yesterday and now driving the car today I have some fault codes pop up. JB4 clears some but there are still 3 with no description that won't clear and need a little help on y next steps, please.

Any help is appreciated thanks !!!!

edit: Looked up the codes and managed to find the top one relating to a misfire or intake sensor which seems to tie in with the air intake install but not sure whats triggered it, everything is installed correctly and in plugged in?
