Noticed the other day that the wording from under the driver's seat and come out, now I presume that this is for the heated seats, now judging by the other seat it looks like they're just soldered to the metal bar that holds the seat cloth down but I'm not quite sure, could anyone confirm this for me? Cheers

Re: Heated seat wiring
There's two heated pads, one in the backrest, one in the base.
Those wires look like they've pulled out from the multi plug - check the wiring underneath the seat

Re: Heated seat wiring
Also, it is nigh on guaranteed that the wires on the lower seat pad to the thermostat will be broken. I had mine out last week and attempted a repair, it lasted about two arse cheeks before coming out again. Will be attempting a cheapo eBay retrofit tomorrow as the 480 is doing another week of daily duty next getting hammered to work.
The pads are connected in series, so the break in the bottom cushion knocks the back rest heating out. You can check the resistance of the pads from the plugs under the seat, there should be a few Ohms resistance, not open circuit. This requires you to use your electrician brain when checking the resistance of the backrest if the bottom part has a break in the wires.

Re: Heated seat wiring
Definitely from the pads, ends are soldered and the other end still in the plugs!

Tbh I can't stand heated seats, but as it's there I thought it might as well be fixed instead of two wires hanging about
So test resistance and see if that's okay then try take the seat cover off and either solder back on or buy a new cheapo pads from eBay would be the best bet?

Re: Heated seat wiring
I'd certainly give repair a go. I was lucky with one car and my repair to the thermostat lasted but not on this one, the wire is just too thin and brittle I guess. The break will likely just be on the bottom part and the thermostat can be reached with just the cover opened up, rather than full cover removal, which is trickier than it looks.
The seat is is unweildy so I prefer to split to before removal. If you wind the backrest back, you will see two roll pins that are the hinge-- they are only held in with a Terry pin. Then you can take the backrest out, test that for resistance; then take the base out and work on it in a more manageable way.
