So far my new C4S launch Coupe is a blast. I'm only at 1,200mi and ran the tank into the "reserve" zone...was rushing to get to work last night...and when I went to gas up this a.m. afterhaving purchased 5 gallons, the fuel gauge remained unchanged to the degree of counting down the remaining miles to zero....(10 mi drive home). The car sat all day and this p.m. I filled it up...the total gallons jived with tank capacity. Initially the guage showed 3/4 full and within 5 minutes of driving, worked its way up to full. Any ideas or experience with this? It is an 8/08 build and I purchased it 2 weeks ago with 34 mi on the odo. I'd like to trust the gauge/s...all of them. This is my 4th fill up I believe. Thanks!
