Still got this problem, had a mobile auto electrician out, he did get rid of the light but it came back a few weeks later. Just waiting for him to come back out.
Need to find the short to ground ( cars don’t have an earth!!!). Careful methodical testing needed. Probsbly a loom fault
They commonly had airbag / seat belt loom connection problems under the drivers and passengers seats. They have a repair kit available for when it comes back.
