another weird result is now the odometer is reading what its previous car had, not my car. apparently in older audis, the odo data is stored in the cluster memory. newer audis store the odo data in central memory and feeds that data to the cluster which makes a lot more sense to me. who would've thought that rolling back an odometer could be so easy?
