    Airbag light - SRS Codes 02 , 14

    Hi All,

    I have seen all the posts on the airbag light going off for the seat belt sensor but has anyone gotten the codes above? It says its the left side airbag sensor fault. Does that mean is a bad airbag or a bad sensor? Does anyone have any links to resources about this particular problem? I have looked through the archives but haven't seen anything about this specific problem, I am trying to figure out if I need to replace the air bag or the sensor.

    Thanks in advance!

    I haven't seen that one...

    It's usually a pretensioner fault (as you read) that just needs clean contacts under the seats. As cheap of a fix as it is, you might try cleaning them with deoxit just to see, and if it doesn't clear up, my next stop would be the dealer (shudder...).

    Re: Airbag light - SRS Codes 02 , 14

    Turns out that the Peake SRS reader doesn't go quite far enough down the fault tree to accurately define the fault. It's either in the steering wheel clock spring [if your wheel squeaks when turning this is a good bet] or it's in the airbag itself [unlikely]. Just going thru this myself. If you're lucky it's the clock spring which can be fixed by removing the wheel and then lubing the spring as shown in the ETK/TIS.

    Good Luck

    Thanks Bob.

    I DeOxited the drivers side airbag connector plus the connectors under the seat, no luck on either same code 14.

    Anyone have a link on how to pull the wheel and clean the clock spring?

    Also, the code says "Sensor, side airbag, left, data fault" could it be the sensor itself? Does anyone know where the side impact sensor is located? it doesn't look like it's located in the door. I have downloaded the wiring diagrams but it doesn't really help with location of the actual component.

    Thanks!

    I don't have side airbags, but...

    This sure sounds like resistance problem ;ie, dirty contacts. I would do the same thing to the side airbag that you do to the drivers airbag, deox and lube with contaCT LUBE.

    You need to get a copy of the ETK and TIS so you have all the repair procedures. Available on E-bay for low cost.

    Removing the wheel involves removing the large center nut. Once you have the wheel off, look at back of wheel to see the clock spring. Clean it with DeOx, n o need to remove the spring. Then look for the black round plate in back and lube it with lithium grease[just a little goes a long way] I'll bet your wheel squeaks. This will fix that also.

    Good Luck.

    Thanks, I will give it a shot, I just need to find out where the side impact sensor is. I actually have the ETK & TIS system and for the life of me I can't figure out how to use the damn thing.

    Per the new Bentley Manual...

    The sensor is located under the carpet, close to the door sill, on the brace that the front of the seat is mounted to. It looks to be an inch or so in from the front outside bolt (stud) that holds the seat to the floor. I can't tell if the sensor is mounted to the front side of the brace or the back side of the brace. The manual recommends removing the seat. I am looking on page 721-9 of the "new" Bentley Manual.

    Thanks VNC!!!

    How is that new Bentley manual when it comes to airbags and diagnostics? I spent 2 hours on the TIS system last night and I found only 3 articles for them, I either have no clue how to use it (most likely) or it really sucks, or the version I got is missing stuff, it says it's from 2001 and my Z3 is a 99.

    Re: Check your e-mail

    Just an FYI, pulled the seat and under the carpet lay my side impact sensor. I took it out and cleaned the contacts and ground but error codes still persisted. I bought a used one of ebay for $20 and replaced it and that fixed the problem.

    Thanks to everyone who helped me! I appreciate it!
