Speedometer reading at least 10% faster than actual speed. Brought car back to the dealer explaining the inaccuracy, was told verbally speedometers are gauges not meters and can only be designed to guess the actual speed, they cannot report actual speeds. Written explanation was a 5 mph difference is a normal variation of speedometers by all auto manufacturers and the car was performing as accurately as all other vehicles. Technician, who also drives a Jetta, test drove the car and noted speed readings were the same as his Jetta at similar rpms. His car is also apparently reporting speed 10% faster than his actual speed. At freeway speeds the 10% variance in speed accuracy is greater than the 5 mph difference to be expected in accordance with their explanation.

Speedometer reads incorrectly. When speedometer reads 70 mph, actual travel speed is 65. This is based on my gps in the car. Called VW (ref#70260633) and both the dealership and the customer care number said that a 5 mph differential was within sae specifications. Not knowing how fast a car is traveling is a accident precursor. Driving too slow on the interstate can lead to accidents from the rear, and trying to guess how fast you are going to compensate can lead to excessive speeds.
