Well, while still pondering how my mileage on full tank has reduced from 420miles to around 350miles, some series of problems have started with my vectra.

The bulb light on dashboard has been on constantly for the last two and half weeks. I have been checking all the bulbs on daily basis and they are all fine.

Yesternight, the car swerve a little bit about three times (my speed was not even up to 20mph then).

Now tonight while on the way to pick up someone and just after driving for about one mile, I slowed down completely at a junction and on connecting another road, the car lost it's rev and at the same time the ABS and traction light came on.

I have switched off engine for sometime and restarted the car but the lights are still on.

Car manual says to take it to dealer but can someone tell me what could be causing all these please?
