Drivers electric seat problem

[tobrid]

Superb Mk IV

After my wife had driven the car recently none of the drivers seat functions worked but the passenger seat electrics still worked fine.  I reasoned therefore that it could not be the fuse. As the drivers seat has a memory function I deduced that there must be a microchip in the circuit and that maybe this had got 'scrambled'.  As there is power available to the seats, even when the ignition is off, I pulled the fuse, waited 10 minutes and replaced it thinking that this might 'reboot' the chip.  EUREkA!
