When my FPC died in Australia (original 2004 design) I pulled apart the circuitry through curiousity(encapsulated in silicone rubber) and I strongly suspect the capacitor had failed as it fell apart. It's probably the hottest running component which is why it has the heatsink and fins.
There were a few small power handling IC chips on the small circuit board but it was definitely not for home repair unless you were good with electronics, had the required test equipment etc etc. Easier to just replace it with the 'upgraded' item (which has apparently been upgraded again - black painted item).
I took the advice on this forum and cut off the blue connector which links the (now dead) FPC to the fuel pump, then made up a 'flying lead' to plug into the accessory socket. If my FPC goes again I will use the home-made lead to run the fuel pump and get me home/to a dealer. If that doesn't work I'll use Carole Nash helpline to get recovered.
If you are that worried about failure, ask your local dealer if they have any failed FPC (or ask to have on put aside next time they get one) then you can cut off the wiring connector and make your own 'get you home' lead up.
