My 1.3 Charade seems to be using too much petrol. In litres and kms it is at about 8 litres per 100 kms and as I believe it should be at about 5.5 or 6 litres oer 100 kms. I cannot find a leak even though there is a slight smell of petrol when hopping out of the car. The little red warning light is usually on when driving and I have assumed that it is for the small back number plate that does not work, could this warning light indicate another problem within the fuel system? If so does that mean a visit to an expensive garage or is it something I can find? If anyone can suggest where to look for possible faults please let me know.
