Diagnostics Port

I see a large connector at the Front top of my Engine, Im assuming this is for the Diagnostics.
1984 318i M10 1.8L engine
Is it a BMW only tool? I have a old Snap-on 2599 Scanner, the one where you put cards in ( I have the Asian and NA card) Is there also a European card set up for this?? just curious its a track only car and I will be doing some REwiring and will move this port if I can connect to it, if not It may get cut out entirely. Any help is appreciated. Thanks

There isn't much you can read from it, I've never seen anyone use it. The E30 wiring diagrams around the net have the pin out. About the only thing I saw useful was a 'starter bump' that you could use to move the motor while working on it, but other than that, nothing interesting.

Since your car is a 1984, there is almost no use for the diagnostic connector. The 318 did not even have Motronic, it has Jetronic. The later e30's had some info that you can read, but even then there was not much data available from the round port till around 1988.

hey everlast when you speak of "starter bump" do you mean shorting pin 11 and 14? I heard of it but never tried...scared of burning something.
