Speedometer in my E70 consistently shows higher readouts that the real speed. It shows 55 when I'm doing 51-52 according to a stationary police speed warning sign or my GPS. I tend to believe the GPS and the speed gun. The other day I was at the dealership for service and asked them about recalibration. I was told that there is no recalibration possible.

Is this true or does it sound more like the SA did not want to bother taking such work order?


Thank you!
