Exclamation pb with jb4 - 06-14-2017, 02:42 AM

hi guys,

i am new here to tell you about the experience of a friend with the jb4

he has an 335i complety OEM

he bought a second hand jb4 but he meets a problem with it.

he plugged it very carefully and well. the car recognizes the jb4, it turns on but the car has an engine problem and the power is not there.

do you think log or settings have been saved on it before ? how can we put back the jb4 in the original mode or reset it ?

thanks for you help and sorry for my english
