2003 Renault Megane Airbag Warning Light On

Renaul vehicles are known for electrical/wiring/connector faults. It could well be a wiring connector etc.. Remove the battery leads 5 minutes before working on the vehicle to disable airbag system, the fault may be behind the dashboard and not in the steering column !. Also have the vehicle scanned for fault codes before disconnecting the battery. There may be codes stored in the BCM (body control module) which will pinpoint where the fault lies ! Also remeber to have the radio code handy before disconnecting the battery.
