Well I Don't Know If This Helps - After my ENTIRE cluster on my old FWB was found dead a few times upon startup, I searched and learned it was some sort of known loose or corroding connection somewhere. I found the posted, "Hit the top real hard with your hand solution" worked every time. I never cared about the vinyl as I already had a nice cover to hide the 6 cracks everywhere. HTH
Also, as the famous 'fading odometer' is an entirely opposite symptom as yours, then it makes it sound even more like an all-encompassing issue affecting everything else except that gauge. Just curious, does search show you're the first that's ever had this happen?
