I have got a new 08 Mk5 Astra SRri 1.9CDTi(150). This model has a monochrome multifunction display with a trip computer which displays range, average fuel consumption and instant fuel consumption. Trouble is, I find the instant fuel consumption figure distracting because it fluctuates wildly between 0 and 999! I end up glancing at it every few seconds! Is there any way of turning off the trip computer entirely? When the car is turned off the display (very) briefly reverts to a simple temperature and time display, a bit like the Mk4 Astra. This would be ideal for everyday use. Does anyone know if it is possible to adjust the display or will it always show the fuel consumption stats? The manual is no help at all.
