Anyone know if it is possible to recalibrate the speedometer either mechanically or electronically on a current generation Volvo? I ask because the speedo on my MY 2012 XC70 reads c. 2 mph too high across the entire speed band. For example, when the ACC is set for 65 mph, the tach reads 2K, which is correct for 65 mph, but the speedo read 67 mph. None of my other four current vintage Volvos had this issue. I fully expect my dealer and VCNA will tell me that is normal and within spec, just like five quarts of oil consumed between service intervals is "normal". Many thanks for any input.
