    I thought that year would use the older 16 pin connector....type A i think. You can find pinouts for both connectors. here is the twenty pin: http://pinouts.ru/data/car_diag_pinout.shtml

    it's not that simple. before 1996 and obd2, obd1 existed and was no standard. Rememer most of the tools available in the net are for obd2.

    Your E30 does not support a lot of features (mostly the ones we the amateurs care about, like dyno i think).

    Although using the appropriate wirings and circuitrly and programs you may communicate with your e30. the only way i know to speak with a bmw pre 96 with obd1 is carsoft... ( i hope i am wrong)


    carsoft circuitry
    carsoft bmw

    at least this is what i read so far in the net.... i am not an expert...

    ps. in the next few days i am gonna try some custom circuitry for a 316 M40 OBD1 engine + carsoft. I'll let you know the result.

    also the Diagnostic sockets in E30 are of two types early and late.
    If yours has the pacman in the center is the latter, the 20 pin.

    the early's pinout is unknown to me. the pacmans pinout and the early and late sockets are

    Excellent info, thanks for the help. I am probably gonna wire my own connector and will contact BMW about the proper wire ends in the diagnostic connector. Has anyone used another end that fits? The BMW part number is 61 13 1 376 191.

    Thanks

    BTW in the photo with the late socket and only in E30


    1. wire with no resistance (i don't the term for that in english, shortcircuit maybe?) the pins in red color with ignition key in OFF position.

    2. Turn the key to ON (without starting the engine) for 4 to 5 seconds max.

    Switch off the key and unwire the pins in diagnostic socket. This should erase the I_WANT_SERVICE indication/leds.

    E-46 Daignostic socket

    Could you enlighten me as to the location of the diagnostic socket for a BMW E46? (2001 325). I can's seem to find it under the hood.

    I don't know exactly where it is in your car, but most likely it is within sight while you are seated behind the steering wheel. Look around your center console, under the bottom side of your dash....its probably a plastic cap that slides out of the way. BTW....All...I got my cable to connect to the 20 pin socket and my laptop saw the connection immediately. I guess in my model car they just didn't connect to the ODDII port inside the cab.
    Who knew??
