Hi Adam. First of all welcome to the club. It could well be the connections under the seat, especially if the seat has been moved about recently. Always disconnect the battery first though when it comes to these and yes, it may well be worth re-seating the connections. It could also be the occupancy mat in the base of the seat. These have a tendency to go and may need replacing. I have no idea how to do this though but am sure you could find out how on the net. Alternatively you could look out for a bi-pass device on eBay that tricks the system into thinking that someone is sitting in the seat even when the actual sensor isn't working. Good luck
