Am I missing something here or wouldn't it be easier to use the inside bolster from a UK passenger seat to repair the outside bolster on the drivers seat?? Also there would be even less wear on that bolster than the outside bolster from a LHD passenger seat. (Ow my brain hurts 
)
Looking at the seats in my Ed30 this may not work, the outer bolster has weaker threads to allow the airbags to tear through the seat and open up. The non airbag bolster has stronger thread? So a RHD passenger cover swapped to the drivers seat will have the weaker airbag stitching now on the inside, not the outer side (make sense??)
SO a LHD market seat would be better as the passenger seat from that will have the correctly orientated stitching.
As Pudding has mentioned here (or might have been another thread) the prices for these as spares fromVW are outrageous. A good upholsterer matching the leather is maybe gonna be the easier route / most economical.
