Are we sure that it is impossible for the airbag to deploy? 100%?
There maybe a time in the future when  this becomes useful but I wouldn't want to take any chances.

Then they came for the Jews, and I did not speak out—because I was not a Jew.
Then they came for me—and there was no one left to speak for me.

If the airbag light is on then none of your airbags will work!!! I also think the pretensioners will be deactivated.

I was going to suggest the same thing but with one important addition..put a fused resistor in there to allow the rest of the system to function if you need it!

100% - it's unplugged so can't be triggered.

the wiring diagram suggested I was looking for just a two wire connection to the passenger airbag, one yellow, one yellow-black (see below).. that's exactly what I found so yeah, I'm 100% happy it's not going to go off

I dont agree with you there, but I confess I dont know for sure.  IMO it just wouldn't make sense (and hopefully wouldnt be allowed) to have a safety critical system like that completely fall over just because one of the components it's attached to goes down..    You can see from the diagram that all the tensioners and airbags have their own dedicated channels to the controller, I'd be very very surprised if there were any series connections between them.

As you say, I also don't know for sure, but as far as I am aware, if the airbag light is on, the system is disabled.

For the sake of a £3 resistor from eBay, why take the chance?

Buy yourself one of these, disconnect battery, plug into the car loom (not the airbag side!) leave battery disconnected for a while and the light should go out and stay out. You are safe in the knowledge your airbag and pretensioners will work and the passenger airbag will be off.

You could of course wire in a switch with the resistor on one side and the air bag on the other. That's what I would do if I needed to turn if off sometimes.

Can we not just get a fellow pre-FL owner to have a peek for us, and install a rocker switch or something where the key switch is on pre-FLs?

An irony here is that it is not an offence for the airbag not to be connected but it is an offence (MOT fail so the car is un-roadworthy) for the airbag light to stay illuminated. To pass it must come on when the ignition is turned on and go out when the engine starts.

Switch has to be the best legal solution because you require a rear facing or whatever baby seat to be fitted.

(Fault code on my Z3 indicated a faulty passenger seat pre-tensioner which in reality was a corroded connection under the seat so the light wouldn't go out and I couldn't reset it so it failed).

Hi everyone, reading this thread with interest but I still have the same original question.. If I can't disconnect the passenger airbag is it safe for my 2 1/2 year old to sit in the passenger seat in his car seat? I read somewhere about risk to the child if the bag goes off..then its ok as long as he is in a proper child seat...I am a simple soul who craves a straight answer! lol

I reckon if my 4 year old is in her car seat and the seat is all the way back,  it's probably best to have it on. That's assuming the force will be less by the time it reaches her with the seat all the way back,  and also assuming the seat belt locks sooner rather than later
