I need some help to diagnose the root cause of the bizarre things that are
happening with operation
of the cabin electrics my 2003 Quattro Roadster. The story goes like this.
First the average fuel consumption started providing bizarre readings, jumping
from 12 to 45
litres/hundred kms and then just rolling out wide ranging readings while the car
was stationary with
the engine running. All other dashboard information is perfect, except distance
to empty, which
varies with the reported average fuel consumption.
Next, the Bose audio decided it had lost power and went into safe mode. Since
it was re-activated
with the security code, about a week ago, it has worked perfectly.
Most recently the auto feature of the passengers door window stopped working,
both up and down. The
movement of the window was fine if the switch was held. This morning the auto
feature was working
All this time the average fuel consumption readings have continued to come from
another planet. The
car runs perfectly and all other dashboard information, date and time, audio
average speed, spot fuel consumption, etc., including the test function appear
to be operating
I am concerned that a visit to the Audi Centre could result in a very expensive
without actually identifying the real fault. All ideas gratefully received.
