Two things! First how does the dealer zero the computers counter since last oil change? Second, how do you change computer to read Fahrenheit from Celsius?

 

To change that interval :turn the key to the second position and hold the odo reset button, tst will appear. keep holding until rst appears. press the reset again and it will reset the your service indicator
Be cautious as reseting may prevent them from "free" service if you are still covered

temp change is in the manual ... I forget of the top of my head

 

For some reason it doesn't work for the 2002 mini. I did exactly what you said. I wonder if it's just different from year to year. Thanks anyway.

 

Works fine on my 05 . ... figured all were the same ...
Also try holding the odo down then turning the key on ....
