I swapped out my leather seats for Bora ones last month and the connection is under the seat. Module is probably there to but I didn't look too much. I know if you remove the seat ie disconnect the seat connection WITHOUT disconnecting the battery first you will get these code's. Has the seats been removed or this just all of a sudden popped up. Kids messing about where they shouldn't be?
I'd...
Disconnect the battery unplug and plug back in both seat connections, reconnnect the battery, reset code and test.
