Found jb4 in ECU panel
Heyy everyone, i own a 335i e93 2008 near about two years and never knew previous owner had put jb4 in it. The turbos whistle loud but i never checked the panel until today , i was cleaning the car and in panel i found this mess.
Their is no control switch inside the car and i feels like this one is wireless or maybe phone app controlled .
Can anyone tell which model is this or how can i control it??
