Has anyone notice that on a 2002 S60 AWD with 16" wheels, there appears to be a discrepency between the actual traveling speed and the speedomenter reading. We had it check out at the dealer and was told that when it reads 100 km/h the actual speed is 92 km/h. This according to the dealer is within Volvo's allowable tolerance. Doesn't this seem excessive and annoying? Any idea on how to minimize this discrepency? Does this affect the actual odomenter reading as well? Hope some techie from Volvo can help me.
