My son has a 107 !ltr petrol. His airbags deployed some months ago.\nHe's replaced the airbags and seat belts but doesn't know how to reset the ecu/warning light. The airbags and seatbelts came from used parts dealers online. The car has been on a diagnostics machine and no fault code comes up. He's been told the airbags needed to be fitted with the ecu from the car the airbags came from. He's also been told he just needs to send off the ecu to have the crash data removed. Can someone please advise on what steps we should take to sort this.\n\nThanks for any help.
