I have had several error messages on the Instrument Cluster screen and sometimes my car doesn't start. I didn't want to pay the hughly inflated fees to have a replacement fitted. This video demonstrates how I removed the Instrument cluster from my Ford Focus Zetec 56 plate. I cleaned the panel with a soft toothbrush and then sprayed it with WD40 and then brushed it again to make sure everything was covered. Remember not to drown it. I left it to dry for about 1/2 hour (you might need longer) and then reassembled the panel. The engine started and no faults - so far! You must disconnect the battery so that no further damage can be caused. It worked for me and I hope it solves the problem for you. Good Luck!
Update - 01.10.12 - I have had NO faults since I followed the above procedure and I am very happy. Hope this is the case for you !!!
