Air bag light, fitting a time delay circuit

[OlberJ]

I'm having a brain melt here so looking for some clarification from you all.

Bmw 328, fitted bucket seats and air bags removed. Failed mot as air bag light comes on but does not extinguish.

I'm not trying to fool the sensors, rather just wire up a time delay on the bulb.

If I find which bulb it is and then connect a capacitor to the live feed on the bulb, it should light for a few seconds then extinguish, yes?

Air bag light on is fail, not illuminating is a pass and advise.....take the bulb out.

[OlberJ]

Is that still the case with the latest rules?

[OlberJ]

I see from your other posts you're an mot guy.

I'll whip the bulb out.

Muchos gracias.

If it's an led you can put some blue tac over it, then it's reversible, in case they change the regs in the future,have a car in at the moment that someone has damaged the ABS led to extinguish it......that's a fail, so dash away for repair 200 quid, faulty speed sensor was bringing light on ,sensor cost 50 quid.....

Ah no, it's a 99 bmw 328 so bulbs it is.

Cheers.

You'll find a little surprise in there too, there's an LED as well as the bulb!

[OlberJ]

One a failsafe then? Just whip both out?

Or just jam some paper in the bulb hole.

just wire one of these in

You could always just wire in a 2.2 ohm resistor across the pre-tensioner/airbag terminals & then get the light reset & it will come on & off as it should.
