Patrick,
Can you go into your OBC and get the oil level? My cluster gives me a failure notice when I go into it to get the oil level, which indicates that my cluster is more than likely from a TT with the dry sump system which reads the oil level differently than a C2. Not sure if the C4 uses the same oil system as a C2 or a Boxster. I also don't know if the fuel gauge is reading correctly yet, but it does read "Full" with my full tank of gas. The C4 and the TT use a saddle type tank which has a different type of sending unit. The miles to empty reading appears to be accurate based upon my average mileage per tank of gas, but I won't know until I go out and burn some of that expensive fuel.
Otherwise, my cluster works great. I don't know if I'm ready to invest in another cluster just yet. (I'm on my second cluster....the first was fried) But I probably will since little things like this drive me nuts.
