The trip computer has a bias adjustment on both the green and red digital
dash ur-quattros.  Basically, you can set the thing to say what you like.

On the ur-quattro, with the dash cover removed, there are two holes on
the left side of the display unit, sometimes more or sell covered in
tape.

One is marked 'V' (Verbrauch) and provides a divisor for a kind of
integrating analogue computer that drives the mpg display.  The other
is marked 'T' (Tank) and adjusts the fuel level display.

It has more than once occured to me that setting the consumption to
read low (high mpg) and leaving the computer set on that would sucker
an unwary test driver.
