Re: Speedometer lying at high speeds?

["Pantelis Giamarellos" <pantg@otenet.gr>]

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
Kph.
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.
