I am glad you asked the question. Sorry you got the preachy replies versus what you asked for.
I am in the same boat, 1990 S4 with a failed Airbag module. The 1990 airbag design is more challenging than later years as the 1990 is one unit with cables integrated, which snake up under the dash...
Seems like it would be easier to overcome in the later models....
With that said, I think there is a certain level of communication between the module (5 in both pictures) and whatever central warning computer exists.
I've gone so far as to buy a replacement 1990 Airbag controller and all the wiring for when I remove the dash, although I'd just as soon disable it.
I hope someone has a better than average idea on how to overcome this but your customer may want to bite the bullet and just buy a replacement airbag control module.
Well, I think if you would please review my unedited first comment on the subject, it was exactly the opposite of what you posted. I said specifically not to get involved and send him somewhere else. But - I get your point about not liking my post advice. The 'ignore' function works on your computer, I know because I've borrowed your computer before, and ordered beer and pie from it. As always, if you think I've overstepped the bounds of etiquette you can work with the mods and see about having me banned. Not sure for what, but you can try.
Should I start calling you Sterling in relation to the drama here?
Personally, I think the decline in the thread was more from your post 3 nastygram in reply. Strangely, Greg agreed with me(Sorry Greg, it won't happen again) on the facts in evidence.
My advice was exactly that to the customer. Maybe I should have typed it slower in my initial post.
Can I apologize again? Mea culpa, mea maxima culpa. Been trying to get out of
this thread for days now, but y'all just - won't - let - it - goooooooooo.
I know it's hard, and you can't resist the temptation, but not clicking on it again is an option
jej3 I've encountered it more than this one occasion with the '90MY and that was exactly how it was fixed before. Replacing the entire set up and it's not an easy, short hour job. This car will most likely end up as a high HP turbo car since that's what the owner specializes in. You should see his 800hp 308GTB.

This post is NOT FOR SEAN.
A new airbag controller is something like $2800. There is a company in Allen, Texas (of all things) that will test and repair your airbag controller for $50. Google airbag controller repair and you will find it. They even pay shipping 1 way. I knew when I was having airbag controller issues that I was not going to buy a new airbag controller.

Who started the drayma here? My first comment was pretty cut and dried, and on point to what you wanted to do; "...am curious to know if anyone has actually done this. - The customer just wants the system gone". How are we supposed to interpret that last statement? What I got back was pure snarkism, and you know it.
Further, why would or should I not click on a thread where I've posted? Are your threads special, unicorn tear threads? Aren't they open to comment like all other threads? If you get advice you don't like, does that make it bad advice? You knew someone was going to take up an issue with you working on a piece of safety equipment by disabling, that's why you didn't want to hear 'just fix it'. Advice you disagree with doesn't mean it's bad, but like the progs you so disdain , you only want to hear people who think/advise the same as you.
Hows that workin' out for ya? You know I know how to do it, because I've bypassed my 90GT airbag faults before. I fixed them, and also jumped around the sensors. Am I gonna put on a public board? I fell off a vegetable truck once, but it wasn't yesterday.
Finally, as for being dense - anytime you wanna go head-to-head on IQs, I'll put you in touch with my Mensa chapter. I CAN answer the ****ing question, and I'm NOT trying to **** in your thread. I sincerely tried to help. Now, I am well and truly done. You may post as much vitriol as you like, I guarantee you the last word. Have a nice day.
Careful or Sean will put you on the ignore list......like he did me and a few others. I don't think he can tolerate well the opinion of others that think differently.

Actually I tend to treat the forums the same way I do in real life Imo. I measure the person and when I see loads of things I don't like about them, I prefer not to associate with them. Occasionally I'll click to see what you post, such as in this thread, to see if you actually have anything of value to add and I'm never disappointed. You typically add nothing of value.
Doc, on the other had is a pretty damn smart guy, sadly he couldn't find it in himself to actually add anything of value to this thread. I know if I've encountered an issue like this than many, many others have also and this could point them in the right direction. I won't put him on ignore, I reserve that to idiots such as yourself and a few others, that I'd not associate with in real life.
No harm done as I wouldn't want to associate with you in real life either but using the ignore option is for chickens that can't handle reality. They should rename it the "kindergarten feature" or"La, la, la, I can't hear you feature"
Interesting how quickly you've responded considering I'm on ignore. Which minion of yours told you to look?

You continue to show fantastic reading comprehension skills, glad to see that's improved a lot.
Semi-retired, as of Feb 1, 2023.
The days of free technical advice are over.
Free consultations will no longer be available.
Will still be in the shop, isolated and exclusively working on project cars, developmental work and products, engines and transmissions.
Have fun with your 928's people!
You continue to show fantastic reading comprehension skills, glad to see that's improved a lot.
Thanks, will check that out.
I understand the problem with the airbag warning light that comes on every time, I remove the battery lead for service on the car a day or two the light comes on. One has to go to the PORSCHE dealer to reset the warning light! That get's old so I removed pin no. 11 the wire is green and yellow in plug no. 3 that is in the instrument cluster. The airbag is still functional but the warning light does not come on! Note I have a 94 and made the change in 96. The drawings for the 89 does not show a line going to pin 11. But for the 90 it does show the pin 11 with green and yellow wire. Warning I did not check this out with the legal dept.
It is extremely unlikely that the propellant is ammonium nitrate and very likely that it is sodium azide.
If the system is intact and working, it is a violation of Federal law for a professional repair facility to disable it. There is no corresponding prohibition on disconnecting or disabling the airbag on a car you own. If, as has been described here, the system is broken, there is no statutory duty to repair it either by the owner or a repair facility. I leave speculating about the potential tort liability of bypassing the warning light to others, but wonder how often our cars are driven by anybody other than the owner.
As others have stated, first gen systems like these are usually bypassed by using resistors to simulate the presence of an intact inflator module when the system self checks.
Insofar as aging is concerned, it is safe to assume that the components were designed and tested with a 15 year service life in mind. IMHO the sodium azide inflators in first gen system are going be much more tightly sealed than the Takata modules.

The light is not what makes the system functional. It will still be disabled, you just won't know it. When the airbag light is triggered, the system turn itself off. Newer cars will disable part of the airbag system so yo still have some of them working but I'm pretty sure the 928 directives both if a problem is detected. So by disconnecting the light, you just put the airbag system on the ignore list.
