How many ohms for airbag light?
I am getting ready to install recaro racing seats, and want to figure out how to install the ohm resistor to fool the airbag light.
So i have done a lot of reading and have seen mixed numbers. I have seen 4, 3.9 and 2.2. I have also seen some people say that they had problems...So which one is it? I know Randy Webb says 4 ohms....anyone else have anymore information?

4 ohm?
Hi , I changed my seats with Sparco Milano's I could not find 4 ohm Resistors anywhere. I have gone to every radioshack in my area with no luck I've also tryed what they had in stock which was a 3.2 and 4.7. No luck the light is still on. I tryed to e mail Randy but no response. The only good thing if you look on the bright side is at least the red light is dead center on the speedo. The seats are awesome. Its so nice to be hugged

Also....... I read in my Bentley shop manual (the publisher not the car silly) that when the light is on ALL of the airbags are disabled. It was not 100% clear on that point but it did say "SRS system is disabled".
Any technoid know any different because I wouldn't have a problem with the thorax (seat) airbag being disabled but I want to know that the others work.
BTW my Sparco Milano Prestige is en route.
ALSO
Does anyone know for sure if disconnecting the battery will reset the light (with the correct resistor of course) as I've seen conflicting answers. Some say that only a trip to the dealer will reset it. If the former then you could hook up a variable resistor (a "pot") and keep trying to find the correct setting.

i'm a tech at honda and have also worked on volvos. if the srs light is on then yes, the entire system is disabled. both car makes i have experience with used 2ohm resistance for the airbag igniter. all service manuals insist that you NEVER measure the resistance of the airbag igniter with a multimeter. i know that logically the few millivolts from the meter probably will not blow the airbag, but if you have ever been witness to an airbag explosion.... man, you do NOT want to mess with that. it is a bomb, plain and simple. our honda test tools are all two ohms and plug in place of the airbag igniter and will keep the light off. although i can't be certain on our minis, on hondas you can reset the light without a scantool by doing a battery reset (disconect battery, hold both terminals together, or use a jumper wire between the two, and turn the key to on for about 2 to 3 minutes). this will suck all the juice out of all the components and probably reset the srs light. worth a shot...

You have to have the dealer reset the SRS light. It cannot be done otherwise. It would set MINI up to possible legal issues if it were able to be manipulated by the owner.
As for the ohms...4
As to where to find a 4 ohm resitor...no clue. I looked for weeks. Stores, internet, everywhere. Randy Webb has a source....but he never replied to me. Good luck. Let us know if you find them.

Anyone try the battery jump thing that sonichris mentions? I've had that dang SRS light on (again) since I slid one of my seats forward. With a 30k servicing about 5 weeks away, I'm been holding-out so I don't have to make mulitple trips. I'll also address a couple recall notices at the time, and finally my expansion tank... Thanks.

if your srs light came on just by sliding the seat forward, you may actually have a problem, and a battery reset will not clear the light. the srs unit must go through its initialization and see no faults for the light to go out. again i haven't tried a battery reset on a mini so i can't say it will definately work, it depends on what kind of memory bmw used in the srs unit...

sonichris, MINI has known that the wire looms under our seats to be a problem for almost 2 years now. If fully slid forwards or backwards, at least on '02 and '03's, it pulls just enough on the connectors to trigger the SRS light. However, even after pushing the connector together again, to ensure they are secure, the light remains on... That is why I was curious to know if your Honda battery trick would work on our MINI's, again, assuming that the problem that triggered the light has been "fixed." The true fix is to get a jumper/extension that makes for more slack...

IF bmw used non-volatile memory (memory that is not affected by power loss) in the srs unit, a battery reset will not work. BUT, it is worth a shot. what do you have to lose? besides your radio presets, the time, the adaptive ECM programming, your trip odometer mileage.... i have done a battery reset on mine to clear the ECM memory so my car could relearn how i drive with all my new goodies, and if it didn't take about a 1000 miles to reach its full potential, i'd run downstairs, set an srs code and try it myself. but if it DOESN'T work, now i'm stuck 150 miles from a dealer with an annoying light on the tach....

Did you try the battery disconnect trick yet? I am installing my Sparco Milano this weekend and was going to insert the resistor before taking out the seat to see if it works. If the light stays in and the disconnect battery trick does not work then I can run down to my dealer to have it reset (the plug came loose - honest. I wasn't installing a resistor.).

Alan, it looks like Randy addressed your concern. As a matter of follow-up, no, I have not tried it yet, but I certainly will tonight as I could not drive my MINI today - dead battery . She wouldn't turn-over... just a clicking sound...
I have one of those small 13.5 pound SLA batteries, and between doing a couple gauge installs last weekend (one being a voltmeter), and not driving her since last Sat, I guess that was too much for her. When I take the battery out tonight to charge it, I'll try the "trick" for the heck of it. From some brief reading on the MINI's non-volatile mem, I don't think it will work, but what the heck...
I will report back.

drum roll please...
With the battery out, and the positive and negative terminals "connected" together, I turned on the ignition, for several minutes... a la the Honda trick referenced above. I re-installed the fully charged SLA battery, she fired right-up, but the SRS light remains...
Just following-up . I'll hit the dealership to clear it when I'm doing for my 30k servicing, in about a month...
