I took an old plastic credit card (actually a rewards card), and using a single-blade razor (X-acto knife would be handier) I cut out the the shape of two prongs (connected at one end) with dimensions the same as the two broken stubs. Then glued it the front face of the two stubs. Next I enlarged a part of the hole in the main body of the connecter where you insert the teeth of the locking tab, in order to accomodate the new plastic piece. finally i inserted the fixed locking tab, and voila!, the new prongs operate to remove the short circuit when the connector is seated in the airbag socket.

I was then able to reset the SRS light.. Finally! I haven't had time to post the picture of the modified locking tab, but will do so soon.

Again, this is a solution that worked for me. If you're not sure about what you're doing, I suggest you get the door harness from the dealership.

photos of how I fixed the broken prongs/teeth

Here are some pics of how I fixed the broken prongs/teeth by cutting a piece of plastic from an old Vons rewards card.

I glued it to the front side of the broken stubs, i.e. the side facing the short circuit bar (found in the airbag connector socket).

it's amazing how such a simple, no-cost solution is so effective in properly controlling airbag deployment.

I took a slightly different approach but this worked for me as well. Outstanding investigative problem solving patdosa, I love no-parts workarounds!

Side Airbag Connector - DON'T BREAK IT!

A lot of us have broken this Connector. As others have illustrated, the design is a safety feature... but when you have an Airbag tied with a rope while you change a regulator, its hard to figure out the clasping mechanism.

Attached is a pdf from BMW that demonstrates the latching mechanism.

I still have not found a part number for the connector, pigtail, or wire harness.

Rear Airbag Connector - E46 2001 330i

I still have not found a part number for the connector, pigtail, or wire harness.[/QUOTE]

Hello:

Another lesson for me from BMW. I went to 2 different stores today. The first store continued my research and found the attached illustration of possible pigtails for Airbag connectivity.

However, the illustrations are so elementary that it is truly a pain to identify the correct one. I guessed that #8 was the right one by its general appearance. http://forum.e46fanatics.com/images/smilies/cursin.gif BUT (unbelievable) the guy wouldn't get it for me because it was not referenced against my VIN number!!!!

I went to a second BMW store, went through the same exercise, then the guy was so curious that he pulled the part and low and behold it's the right one. The part number is: 61 12 9 118 135

Still have the same Error Code 08

UPDATE:

I took the door apart one more time... with the express intent to change the connector on the airbag. After I disconnected the connector I decided to perform a good visual and electrical inspection. The connector is rock solid, all indents and locks are in place and all electrical connectors are clean. As a result, I chickened-out from splicing in the new pigtail, not trying to save the $38, but rather trying to save the splice.

Anybody have other ideas as to what can cause the Code 08 failure?

I just had a thought, when the error page displays in the P.A.Soft software, it always shows a Date of 8/1. Which I do believe is the date that I changed my window regulator and caused the error. The thought I am having is that the P.A. Soft device is not resetting the controller, only clearing the error bit. Thoughts?

Thanks

That's the PART!!

Thanks to peddlerp, I ordered this replacement wiring from ecstuning and they arrived exactly the same as the one broken on my car. Except that the color of the wiring is different. I was able to pull off the plastic connector head from the new set of wiring and put it on my old wiring, with the experience provided by guys above and some patience. No splice, no glue, everything just went together perfectly as new! Before this I got a "resistance too small" error message from the airbag system through INPA, which means that the short-circuit clip was not in place (it was blown away during the deployment, I think). Now everything is in place, but I haven't got time to actually put the airbag back online yet. Will test it tomorrow and report the final results.

Glad to hear...

I'm glad to hear you were successful in replacing the connector. I'm anxious to learn if the Airbag comes online properly!

Good luck!

Hello everyone, especially peddlerp, I successfully put the side airbag online today. After clearing the fault memory in the airbag module using INPA, the airbag light on the dash started to flash, then I re-read the faulty memory and it showed empty. Then I just started the engine and in a few seconds the flashing airbag light went away. Hooray!! That's it!
