Hi I have a mk3 2004 active sport punto and both air bag lights have come up an I got them reset and they stayed off for 7 hours then came up. What's wrong with them.

you need this video to explain how to reset the light and where to buy the equipment yourself to reset the lights at home



and you need this video to explain why the light comes back on and how its is fixed



having seen your other thread about the heater fan issues it suggest you have a dash loom earth fault which is most likely the original cause of the problem, so you'll need to fix this first
