[Biturbos4] Gas gauge weirdness

           This happened on my car a few months back.  I was getting
confusing readings.  One moment it would say 300 miles to empty, and then
down to 150 miles.  Gas gauge was out of whack also.   The problem went away
on its own.

            I love the S4, just a fun car to drive.  What I do not like is
the computer.  All of the computations are way off.  Outside temperature
reading is always high.  Sensor must be sitting on the exhaust manifold.  I
had a much better computer in my 1987 GTI with a lot more functions.

             I hate the fast up/down on the windows.  Would love to have
manual control of the heater/air-conditioner.

             So strange because the S4 in a drivers car, why are all of the
controls so automatic.

             None of this is enough to make me want to get rid of this car,
just annoyances.
