My driver seat has now become uncomfortable due to the main chusion has become worn out ie flat after 28400 miles of use.

I wonder if I can use a FL seat or it has be early PF seat due the connections for the airbags?

Should fine as you just need to swap the airbag plugs around if they are different.  Also Audi a3 (8p) , golf mk5/6, seat leon mk2 front seats also fit if you are after an upgrade
