instrument cluster swap?

My Daughters Fabia 1.4 mpi has developed a fault and need some advice please.

The car has developed a wiring fault and causes the instrument cluster power steering symbol, oil pressure, brake warming lights to come on and flash. The rev counter and speedo stop working etc  but engine still runs. If you turn ignition off and back on it clears itself. It happened twice today.

The fault code comes up as intermittent instrument cluster and looking on line there is a video clip of exactly the same problem but not what fixed it.

I think the instrument cluster needs changing?

question is if I purchase a cluster off line does it need coding to the car? or does the imobiliser part of the cluster come off the cluster so I can use my original and keep the keys matched.

has anyone taken one apart and could tell me what needs to be soldered as a few people have said it will be a dry joint on the board.

I also got fault codes 00532 and 01322 which I have managed to reset.

Any help much appreciated
