Hi all,
Did a bit of Googling around and couldn't find much about my issue. Both my odometer and speedo are out by quite a lot. On what was according to Google a ~60Km trip, my odometer recorded ~79Km. At 111Km/h (speedo), the GPS reads a speed of 100Km/h. Is this purely a result of the Premium 3.0R running 17" rims in what I would assume is an ECU designed for 18's? If so, how difficult a fix is it? I do have a service due in a few weeks but I'm unsure as to a possible cost for the fix. I'm not terribly worried about the speed but rather the odometer reading overall being way out on what it actually is.
Cheers,
Chris
