Please read the answer i give to this question
"how can I switch off my airbag light on peugeot 206 W reg?"
This should fix your problem as well and the money you save should pay for the device. At the very least it will show what is putting light on and allow you to decide if it is gonna cost the earth to fix.
it will also be of use if the light comes on again with another fault
