I had the airbag light stay on tonight, it flashed once, paused and then 9 more times. It did this twice and then stayed on. Anyone know what problem this could be?

 

I have the same issue.
Dealer checked this, and it turned out the airbag sensor in the passenger seat is broken.
The system does not know if there is a person on the seat or not..
To replace it, it will cost me about 900€
