Hi, After some trouble with my dash, I had it repaired, but before it went in for repair some of the gauges altered. Specifically, the temperature gauge has increased (hotter) but about 1/4 as has the fuel gauge. Usually the temp gauge is vertical, the fuel gauge now says there is 1/4 of a tank when it's empty. Is there an offset adjustment in ross-tech for this? If so, how the hell would I know where to set the fuel gauge other than running the damn car empty!!!
