Thanks for the reply. I just removed the DME from the intake to send off to unlock. I have a chance to purchase a used JB4 locally. It is from a BMW F10 5-series cars, N55 motor with Electronic Wastegate (EWG), Harness Type B. My 2012 335i also have the n55 with harness type B. Does anybody know is this JB4 will fit my car? I've read that a f30 with n55 type B harness will fit but not sure about the f10 5 series with the n55. Thanks in advance! |
Will not fit, you need a PWG E series N55 JB4. Do not buy an F series one.
