right so both sets of seats were ph3? Both have a orange, red and yellow plug?

If its the airbag light (not side airbag) flashing, its a pretensioner issue. try reconnecting the orange plugs firmly.

I did. Lots if times. I then plugged it all back into the old worn seats and was fine so 100% a problem with the seats. They are deffinatly .ph3 seats. But later ones than mine. All the plugs are correct. Connections seem okay as the plugs clip together nicely but I guess the wires can be loose in the plug.
How do you check the pretensioners? Can they be swapped from my old seats if they are gone? Ultimately though, I just want the light to stop flashing so if I cant work out the problem I'd happily do the resistor thing. I just can't find a picture or faq on how to do it to a 6. It seems to mostly be on rallies which only had the pretensioner with the resistor. Is this gaping to be different in a 6 with 3 cables per seat?

if the airbags had gone, you would have both lights on on the dash and you would know about it! generally it destroys the sides of the seat.

Its definately a pre tensioner issue. You can check if the pre tensioners have fired. Look down the belt stalk and if the plastic around the steel cable is wrinkled, they have fired. If i was you, take the ones off your old seats (just take the plastic cover off, 1x 17mm bolt and unclip the cable) and swap them over.

Saying that, if you want to be 100% sure its not the cables, cut the plugs off and solder them. Pug released a recall in 2001 due to the plugs being a crap design. All they did was cut them off, solder and heat shrink.

Just to put a result up.

Both pretensioners had fired so I swaped the both over (cheers stilly) and all is well.
