Well after lots of time & effort, I now have this:
(yellow end parts are the untrimmed foam passat panels)
Also fitted my sill protectors, helps remind me what I'm driving!!)
Heated / electric Recaro's from an Audi S6 8)
Fronts were 3/10 in difficulty to fit (seats are a straight swop but wiring is a bit more difficult)
Rears are about a 9/10 requiring an inch to be cut out of the rear back panels as they're too wide to fit in the passat (doesn't help when the seat foam is bonded to the steel frame and the cover is stitched through the foam)
Also needed modifications to the locking mech to fit and then eventually went in OK!!!!
Base needed all the old mounts cutting off and new ones fitting (I completly destroyed a passat seat base in order to get the required metalwork)
All that's left now is to get the door centres recovered to match and strip the leather from the Audi rear side panels and re-trim the passat ones with it!!!
Also fitted my genuine RS4 pedal set:
