Re: Speedometer lying at high speeds?

Alexander YES your friend is absolutely right.
Audi speedometer lie and are optimistic.

When traveling from Ancona port Italy to London in March 1998 with my wife,
I was able to compare my Garmin's GPS 3 reading with the RS2's speedometer.
The reading on the GPS was 265 while the speedometer one was close to 280
THe GPS readings are almost 100% reliable and accurate since they are a
result of real time comparison of position of the GPS unit. The actual
position of the GPS maybe offset by a margin but this does not reduce the
accuracy of the displayed momentary or average speed.

In addition the car itself provides you with a hint that it is not
accuretely counting the car's speed.
If you follow the climate control's diagnostic procedure and check on
channel 17 which displays the car speed, the A/C unit displayed speed is
always less to the one displayed on the speedometer.
