I just took a 700 plus mile trip on Tuessday in my 2003 9-5 Aero equipped with 17" wheels. I had with me in the cara Pioneer Avic S-1 GPS navigation unit. I observed the difference in speed between the Saab speedometer and the GPS to be exactly 5% error meaning that at 80 MPH indicated speed from the Saab speedo I was actually traveling at 76 MPH. Can this error be dialed out by the service department in software.
The other interesting thing about this is that everything that is calculated from the speedometer/odometer in the trip computer is thrown off by the same amount which I was never aware of! My indicated average fuel consumption rate although still very good after deducting 5% is now running between 26.5 and 28.0 MPG if all driving is highway miles at 75 MPH (actual which is just under 80 indicated on the speedometer).
When I am ready to sell the car at approximately 40K miles it will really have 38K miles on the odometer which doesn't really change the value of the car but is annoying to think about!
