I looked into it and heating elements were going ti cost an arm and a leg from vw like 200 a seat then I still ha to buy climate control unit the kufatec loom(which is apparently for lhd cars so need modified to work) then you need the loom from the elements to the seat base where it plugs into the kufatec loom it can be done but I reckon buying seats with elements in them would be easier and cheaper than trying to fit elements into your own seats. There is threads on here about it and I'm sure the people who fitted them will gladly help you out good luck
