Anyone done any tests of how accurate the A4 speedo is (UK 2003 in this
case)? I normally cruise around at ~80mph in 70 limits and have never been
troubled before but I've now had some (ahem) unwanted attention and wonder
if my earlier cars read 5~10% high and my Audi doesn't.
I've read that the actual speed can be displayed by pressing a combination
of buttons on the aircon control, as follows:
"A/- To access the actual speed display, start your car and then on your
climate control panel press and hold-in both the Econ and Auto buttons or
the Recirculation and Temperature Up buttons. This will change your outside
temperature reading to Fahrenheit.
Then press the recirculation button and at the same time press the upward
pointing arrow button above the recirculation button.
Your climate control screen will change to a different mode displaying 1c.
Use your temperature control + button to display code 17c. This is the
actual speed display feature.
Press the recirculation button again to activate the code and to display it'
s reading in mph."
However on my 2003 A4 while I can get the temp in degrees F as above, I
cannot get the "1c" to appear - as I don't have an up arrow above my recirc
button. Anyone got this to work?
If not it's timing those mile markers, which is a bit hit and miss.
