I have owned my C4 now a couple of years and have had no issues with the StarWars dash, until just recently. This, combined with this thread has led me to do a bit more investigation into the common problems. Although this may be a bit late for this thread, I found a web site that has all the info on these things I will share with anyone that may be interested.... They have all the parts, and DIY info one might need. They do also offer a rebuild service also... very informative:
