Passenger Seat Airbag warning light

[lotsofmarks]

Hello,

I took out my 2018 Sportwagen S cloth seats and put in a set from another mk 7.5, now I have this light on my dash:

Also have the airbag warning light below the central vents,

How can I clear this code? - I figure its relating to the airbags in the passenger seat. Its not something that JB4 reads or clears.

Thanks.
