The car is a 10 Avant and needed over a litre of oil top-up before it's last service and oil change which was in August, I think. Last week it asked for another litre top up (which I haven't yet as I have 502.00 oild and it now needs 504.00) but after nagging us for a couple of days the warning went off again.
Two questions: Is it nomal for it to be so thirsty? - it's isn't driven hard very much as my wife generally has the kids in the back. Or is there something likely to be wrong with the sensor?
