Unhappy OBD-II pin broken off inside my OBD-II port

AutoZone had a sale on the obd-ii scanners so i picked one up for ~$20. I hooked up the scanner to my obd-ii port under the dash and read the codes and the scanner worked fine. then when i removed the scanner, it looks like one of the pins in the scanner broke off and got stuck inside the under-dash port.

Is there any way to extract the broken pin or do I need to purchase a new obd-ii port?

Yes, I see why that thing is on sale. But I don't think the BMW ODB port is on sale at the dealer, though.

Hmmm...interesting problem...sorry you're having it.

First, make sure a pin really is broken off. Just because one is missing on the scanner, doesn't mean it was really there...unless you see a cracked piece of metal there...and it sounds like you're not positive you have one in your port...so be positive...of course!

Then, if it is broken, only things I can think of:

Disconnect battery first, whatever you try.

Try strong magnet, while protecting the rest of the pins just in case there's a weird magnetic problem you'll create. You might be able to pull it down just enough to get hemostats on it.

Stick a pin into the end of the pin if it is slightly protruding...might give enough grab to lever it out enough to get a grip on it.

Vacuum with tiny hose coupled to it.

GL

Hope something I've said helps!

Doug

Ya but It would be a pain to swap one. They arent attached or anything, their just solid wires from the harness into the plastic adapter thinggy.

Its possible that "port" isnt even used for a connection, so you dont have too much to worry about.

If you can describe which slot its in I can check some of my pictures and see if its used. Info might also be in my Bently manual, but lets try this.

Can you tell me which "slot" the pin is stuck in?



(this is the pinout reading on the back side of the OBDII connector, the side that you cant see because it faces up to the steering column area basically.)

EDIT: The part can be found:

Youll need #2


Thats for my 2004 330Ci. I dont know your car exactly so I cant look it up... exactly. But it might just be the same part. Its $4.50...
