I drive a 2008 audi rs4, and my mph and odometer readings are 10-12% higher than actuals. i have verified this several ways. using police radar vehicles, using gps, and using other cars to pace, as well as using the speed check systems. all of them show i am driving slower than the actual displayed value by a significant amount. this causes a few issues. first i am racking up miles on the car that are not actual, affecting the value. second i am being put out of vehicle warranty 10-12% earlier than i would have otherwise, a boon for audi. third i am not traveling speeds i say i am, which could cause safety issues. i am not the only rs4 owner who has noticed this issue, it has been reported by several owners now and audi has yet to do anything. also i am concerned i will be forced out of warranty on my vehicle earlier than i paid for, because of this. 12% of the 48k miles is nearly 6 months of driving. the 2007 and 2008 audi rs4 appear to be the affected vehicle from audi. *tr
