Legacy estate 2.5
Discussion
Teknopug
I've checked all seat connections all look OK - light is still on though - Do I need to reset the system? if so how do I do it? On the wifes VW Beetle which is prone to warning lights I have to plug in a 'thingy' to do this - Is the subaru the same?

AFAIK my car was not recalled for any seat airbag problem

You can reset the airbag light but if there is an actual fault, it will just come back on again.
I have a 2002 and 2005 Impreza and the wiring and connectors are all very reliable from my experience. So I would suggest that there is a loose connection/damaged wire somewhere. Under the seats is the usual suspect as they are the most vulnerable from things being kicked underneath and getting trapped on the runners.
Have you removed the wheel airbag to check the connection? Sometimes the clock ring can get damaged. If you can identify where the fault is, it should be easy to fix. Alternatively, you can just fit a resistor into the connection which fools the Airbag sensor that all is fine and turns the light off. They cost pennies. You need to find where the fault is first though.
Assuming that a 2005 Legacy uses the same system as a 2005 Impreza, you need these resistors: https://www.ebay.co.uk/itm/Carbon-Resistor-0-25w-1...
Bend the wires back and then insert them in the 2 holes from the disconnected airbag connection. If the airbag light goes off, that's where the fault is. It maybe easier to remove the seats.

thanks for reply - no I don't know about the 2 wires under the dash - please tell
It's been 8 years of trouble free motoring so far a great car

Open the flap under the dash to the right of the steering wheel, where the immobiliser panel is. Tucked up there are two (green from memory) wires with a male and female plug on each end. It is sometimes easier to find them by removing the end panel from the dash if they have never been used before they may be still taped up to the loom. Once you've found them;
• Connect the wires together.
• Then turn on the ignition so the dash lights up but not so far that the engine turns on.
• As the dials do their sweep press the trip reset butting on the instrument cluster.
• The trip mileage display will change to show any active codes.
• P codes are for powertrain (engine gearbox) and C codes are for the chassis.
You can’t reset them but in my experience with my Legacy if you cure the problem the lights gout by themselves.

Sorry for the long delay in replying - Finally got this sorted
After several weeks of frustration, all it turned out to be was a knackered alternator which also managed to knacker [one cell of] the 6 year old battery. I simply wouldn't believe that a knackerd alternator/battery combo would light up my ABS & airbag lights - but hey that's modern electronics for you

For anyone with similar symptoms - the key is to check the battery voltage after leaving it standing overnight - it needs to be at least 12.5 Volts + when under load [connect a old headlight [main beam] unit to it and leave it on for a few minutes] - If not swop the battery, for a new one - also check:-
The alternator output voltage needs to be 13.5 Volts+ with the engine at tickover, if not then you need a new alternator too [my shiny new alternator output voltage is 18Volts] - Easy to check both of these with a volt meter
Once again thanks to all who helped on this
