Mine is not a mileage calibration problem. What is really happening is
fuel gauge and the estimated range indicator work well together, but
a part of the auto-check system is triggering at the wrong moment,
getting a wrong reading from the fuel float. However, it can't be a
float system as then the fuel gauge and range indicator would be grossly
inaccurate, but they aren't.
As for the fuel range thing, isn't this estimated on the last 30km
is that the average fuel consumption that is estimated on the last 30km
the fuel range worked out accordingly? My average consumption indicator,
estimated fuel indicator and fuel gauge (dial) work perfectly, but the
autocheck system triggers on the wrong level of signal from the tank
I spoke to a guy who used to work for VW/Audi here in South Africa, well
least for a service division and not the factory, and he tells me there
a sequence of buttons to press when you start the vehicle that will
computer and auto-check system. But I'm not clued up on that. Anyway, on
this topic of pushing buttons, if you hold down the button that will
through the auto-check displays and do so while the car is off (ignition
position 0) and then turn the key to the start position and "56" is
on the LCD. What is this?
It would be nice to simply push a few buttons to get the thing to reset
completely, but I think in my case it is more a problem with some
needing to be adjusted to trigger the "empty-tank" indicator.
