Odd Airbag Fault - 2016 VRS

This morning had the airbag symbol come up on the dash and at the same time both lights for the passenger air bag above the hazard light switch were also on. Parked up and turned the passenger airbag off, restarted and the fault light had gone. Turned the passenger airbag back on and the fault did not reappear. Has anyone seen this before? Warranty has three weeks to run so will probably get it checked out anyway but just wondered.
