I have a '03 MCS with about 45k miles with the Nav so the fuel gauge is a set of LED's under the nav screen. I have noticed for a while now (maybe a year) that my clock (on roof near rearview mirror) and fuel gauge will flicker on and off... Now it used to only happen quite rarely so I knew the dealer would say they couldn't replicate it. But now it has been doing it more and more often to the point where it will do it atleast once every 5 mins or so. My first thought is that it is a faulty ground. I also have IAN's mini circuit and a "add a circuit" but I have checked those connections and both are good. Plus those shouldn't be on the same circuit anyways. I haven't read of anyone else having this problem but please chime in if you have or if you know the fuse for the clock.
