Hello All,

(First post!)

I've just acquired a Vectra Life CDTi (150) Estate. I was hoping someone might be able to help with a few questions:

- what exactly does the front windscreen demist button do? I thought it automatically set the air upwards and set the temperature and fan to max but according to the manual, you're supposed to do all that as well as pressing the button.

- how much fuel is left in the tank when the warning light comes on, and when it starts to flash (can't seem to find that in the manual).

- I've read lots of posts about people getting some incredible mpg figures from the CDTi, but what's the worst I should expect? My daily commute is just 10 miles return through a number of small villages. I was previously getting around 21mpg (petrol). The diesel has increased that to 35mpg. Is that about right?

- Finally, when I went to start the car the other day, none of the instruments or warning lights were working (although the car started OK). The fuses were fine and the instruments started working again when they were re-inserted. It's been fine since but it's booked in for the dealer to have a look at it anyway. I'm guessing the control unit just needed rebooting but is this a common fault?

Thanks in advance.
