The first thing to do before starting this repair is to disconnect the battery!
I do not disconnect the battery because I am familiar with the system and know how it operates. With that said let me begin. (ALSO APPLIES FOR A4'S)

nice write-up!!!! I just had the Airbag throw a code a couple of weeks ago. I haven't had the time to look into it yet, but this looks like something I can tackle! Part numbers for the wires and butt connectors would be cool, or just what gauge wires so I can rummage through the parts bins in the electronic assembly dept at work! LOL

Thanks again man!!!!

wire-000 979 009 (x1)

great write up!

just so i understand this correctly, basically you're just cutting the yellow clip out and then using something like 14-16 gauge wire with butt connectors in it's place? and this eliminates the sometimes faulty yellow connector?

This also happened to me in my 2005.5 b7 s4 but that connector has 3 wires in it. I did the same thing you guys did but with 3 wires and all my problems went away. (i had the same issue in my early 2006 GTI and fixed it the same way)

It shouldn't. If the airbag light is off then they are functioning properly.

Firstly, thank you for writing this up.

I got this code:
1218 side airbag igniter
passenger side (n200)
001 upper limit exceeded

Seems this situation can happen on either side and the problem can be fixed the same way. Here is the other side on a VW, but looks the same.

Question....are the part numbers for the wires and butt connectors Audi part numbers? Can you buy those at the dealer?

h_curtis
02-08-2011, 12:05 PM
Thanks for this information. It worked great on the passenger side. The only difference is it didn't say, "sporadic". It said something else, but I didn't write it down. None-the-less, it worked the same.

02-13-2011, 10:02 AM
Wow, those part numbers listed are the most hilariously overpriced items I've ever seen, lol. That's $8 for the wire and $3 per butt connector, making this repair cost $20 at the Audi parts counter. Talk about markup. I'd get some wire, solder it in, and be done. Solder would be a more reliable connection anyhow. And when I think airbags...I think reliable.

This is a VERY nice DIY. .

A lot of Audi wiring fixes - most noteably the wiring supplying the coilpacks require crimp/butt connectors due to changes in resistance that the solder introduces into the circuit. This resistance change [U]might affect future proper operation of the ckt.

I got you beat, I went to the local dealer here yesterday to pick up these parts.....

Wire - $25
Connectors - $10 EACH (SERIOUSLY!?!?!?)
Total $65

Looks like I'll be doing the Autozone/RadioShack version of this fix. Anybody know the gauge of that wire?

you can pick up the stuff to do this job at oReillys...not supposed to to solder...especially on the airbag circuit...

hmmm...I also wonder if this will fix my problem. I had my airbag light come on about a year ago. But I've been lazy and haven't gotten around to checking the code.

Guys, for the record this is 0.5mm diameter wire which is 20 gauge (AWG). It sells for $0.19 per foot at O'Reily Auto Parts. While you're there, you can pick up the butt connectors for $0.99 each. So assuming 2 feet of wire (allowing for margin of error) and 4 connectors, you're looking at $4.40 + Tax. I can't believe my dealership wanted to charge me $65, dear god.

Ok so I went to do this weekend and the bottom of the b6 is a little different, and its pictures are moved right now.. so before I cut it out I want to be sure. Is this the correct connection to cut out?

I cut out the connector but still have an airbag light...I'm guessing I'm going to have to VAGCOM it to clear the code???

I'm guessing if your car has never had any airbags deployed, then probably yes. If you have had a deployment and sent it to a body shop, take it back there and tell them to fix it. Most reputable shops offer lifetime warranty on their repairs. Even if it doesn't fix that problem, you should probably just go ahead and do it anyway...

Hey guys, need a little help here if possible. I have an B6 A4. I'm getting a diff code than what I've saw on here. I did the wire trick with the 2 wires and connector and deleted the code. The code comes back a second after I clear it. The code I am getting is. 01221- Crash Sensor Side Airbag; Driver Side (G179) 012-Electrical Fault in Circuit - MIL ON Any help is greatly appreciated.

P.S. Some of the DIY photos on this thread are missing with an error code.

wire-000 979 009 (x1)

Look at the comments above^^

It's a very easy fix. If you pay attention closely in the picture, there is a blue and black wire that were cut. After that you would cut on the other side of the connector to eliminate the connector. You're just adding an extension to each wire so they reach each other without the connector in place. So you take the wire you bought and the butt connectors and connect blue to blue and black to black with the extra length of wire. I was confused at first also with the most important pictures not being hosted anymore but after reading the comments it's a very simple procedure.

Do you know what airbag code your getting? I thought this was going to fix my problem. Turned out being a bad sensor I replaced used for 25$ to get the light off.

I was a bit lucky or at least for now. I was able to just use compress air to clean both connectors and cleared the code. I also found this video tutorial:

https://www.youtube.com/watch?v=LHPE-K-5Jiw

That video is showing the wrong connector being modified. Correct me if I'm wrong, but the connector we're supposed to be replacing here (according to the TSB) is the one attached to the underside of the seat, not the one connecting into the floor, although the actual plug does look the same on both.

If you did it according to the video, how would you remove your seat (if you needed to later) without having to cut up the wire again.


I received the 01218 code earlier this week and will be attempting this repair soon. I will return with results.

CrazyCal
06-04-2015, 11:57 PM
I completed the repair per the TSB. 20ga wire and butt connectors, but I'm still getting an error code. The difference with my code versus the other codes I see is that mine is "lower limit exceeded" instead of upper limit exceeded. Ideas anyone?

Gsf1200m
05-16-2016, 04:40 AM
Never mind, I checked my code again and I think it is the steering wheel airbag.

What connector are you guys replacing? As far as I can tell I have the yellow plug at the floor, then it is a solid connection up to the air bag. I don't have the yellow plug under the seat where all the other ones are like the picture shows.

Just an FYI to anyone who gets a 01217 - Side Airbag Igniter; Front Driver Side (N199): Upper Limit Exceeded error, and the airbag light stays on. For me, the fix was a new side airbag sensor, which lives behind the driver's door card. Part number 8P0-955-557. That's a zero after the P.

Just bought an a4 b6 USP 2004 and airbag light is on for this same issue. The connector is already deleted and still having the airbag light. Any ideas ? What airbag is it related ? Could I just change the seat ?

First of all, you need to clear the airbag fault with VCDS. The airbag light will go off. Then you need to see if it comes back on, and only if it does do you have a problem.
