Air bag light again

mr happy · 7th February 2016, 13:36

Hi EVERYONE

the airbag light stays on on dash, I have tried unplugging the plugs under driver and pass sets and reconnecting this temporary fixes it for a few days but then the light comes back staying on all the time. I have tried tying up the plugs with electrical zip ties but still have same outcome. Can I cut the plugs off and use normal electrical connector blocks in place of them? at least this would count out faulty plugs as the problem, I think I could do it without removing the seats or is it something else? regards Mark

Try an electrical contact cleaner then reconnect/disconnect several times. If that doesn't work bend the pins, just a fraction.

I know from experience that tracing the cause of an airbag light can get very frustrating, I would suggest a T4 session to find the problem but I have no idea where your nearest T4 might be. Maybe drop either w44nty or freddie a PM, they are both in Norwich and might know of a local T4.

mot in the morning for mine, ive just gave them a blast of spray and a re-plug which fixes it for a while..

Jules cut-off mine and replaced with aerospace connectors as a matching pair. never had a re-occurence! The issue is one of corrosion and it does not require dampness for it to occur, it is caused by a slight difference in electro-potential as the connector on the seat may be from a different supplier to the connects of the loom, hence a difference in metallurgy. This issue is not uncommon on many makes of cars.

Has the carpet ever been wet?

Does the car have Sunroof?

Side impact Sensor is a common problem if the carpet has been wet at any stage and allowed it to corrode.

Probably not this but its worth considering.

If working on the underseat connectors doesn't cure it I would always suggest a T4, avoids all the frustration and potential expense of trying to find the cause yourself. Mine turned out to be a defective driver's seat belt pretensioner, nothing to do with the wiring, I doubt I would ever have found that out myself!

I had to change the pre-tensioner, the part the belt clips into by the handbrake. That cured the light on. Done all the bits under the seat as well.
