Airbag warning light has come on in my Peugeot 206?

Your car is still covered by the 3 years manufacturers standard warranty which means when you take it to your dealer to fix they will do so free of charge.

The airbag system does NOT have sensors which check the system constantly.

The only sensors are the impact sensors which consist of a ball bearing in a tube of high viscosity jelly, under an impact of >80 g the ball is forced through the jelly to complete the circuit and set off the airbags.

The system is controlled by an ecu, and if the system detects any open or short circuits in the wiring it will memorise a fault and illuminate the light to let you know you need to take it to a dealer.

The most likely causes are the connections under the 2 front seats for the seatbelt pretensioner and for the side airbags if they are fitted, simply a case of cutting the connector out and joining the wires with a heatshrink solder type sleeve.

The other possibilites are a faulty comm 2000 unit, this would cause a 'drivers level 1 igniter open circuit or short circuit to earth' fault, though it is less common but not unheard of for these units to develop airbag problems.

The actual airbags never usually cause faults.

There could also be a faulty ecu, or a power supply problem to the ecu.

If your battery has recently been flat then it can cause 'temporary supply voltage' and 'passengers airbag deactivation not defined' faults too.

However, whatever is at fault you will need to take it to your dealer to clear the fault codes even if you fix it yourself, so why bother trying to fix it when they will fix it for you for free?

To anyone reading this.

NEVER attempt any work on your car's airbag system unless you know exactly what you are doing.

The airbag components (airbags, side airbags, seatbelt pretensioners, curtain airbags) are pyrotechnic devices which means they are set off by a small explosive charge.

If you inadvertently set off an airbag component when removing it, or when your head is near it you could kill yourself. A few people die each year in the UK alone working with airbag systems when they shouldn't be.

And don't use a multimeter to test the wires either unless you know what you are doing as checking resistance of an airbag WILL detonate it.

RE:

Airbag warning light has come on in my Peugeot 206?

Whilst driving last night the airbag warning light suddenly came on. I was driving normally on urban roads, I have not hit anything. This light has come on and I cannot get rid of it. The car is a 55 plate Peugeot 206 and has only done 7000miles without even a hint of a bump.

Im guessing it may...

You need to get it fixed quickly. The light is telling you there is a fault on the firing circuit. If you don't get it fixed you might find your head through the windscreen in an accident and then it will not seem as expensive. Alternative it might go off when it is not needed. That would certainly be interesting! You won't get it through an MOT at the end of the third year like that. The airbag is an explosive device and you can understand a garage that does not hold the dealership being unwilling to help. You really do need to get the agent to sort it out and quickly -- it's all part of the cost of running a car these days.

It will be nice to take it to a peugeot dealer in oredr to run a test for codes. Most of the time, it's caused by a problem with airbag ECU.

This is a common problem with the 206.

There are sensors in your car that check your airbag constantly. When the sensors don't work, the light shows, indicating that you airbag probably won't work should you need it to.

This is no way affects the performance of your car, except making it slightly more unsafe.

If your car is under warrenty, simply take it back to a Peugeot dealer and they will arrange to have it fixed.

If not, any Peugeot accredidited dealer will be able to fix the problem.

It means that your airbag may not inflate in an accident.

You can either ignore it and drive very carefully ( but there's no way you can control the other guy ), or get it fixed.

It will not affect the operation of the car, just the deployment of the bag.

Most likely it is a sensor gone bad. You'll need to take it to a dealership, or a mechanic who specializes in Peugots.
