Good app for Wiring BMW schematics .
Go to app for bmw electrical diagrams
Very very handy app for bmw electrical drawings/schematics and even module/hardware types and locations. App developer very helpful and fantastic communication even through direct email. ++++++
Missing model years
Unlike what it says, App is missing wiring schematics for F33 before 2017. I contacted the developer and did not hear back. Waste of money.
Response from developer
I think you are looking in the wrong place I checked the app and found the engine you are looking for by following this path 4 Series >> F32/F33/F36 >> 428i And here you go And I apologize for the late response.
