High fuel consumption 
Solved
Volkswagen Vento 1997 180000 miles
Buddies, please help me. My vehicle has got an extremely high fuel consumption, around 4 km per liter. It was scanned but no error was indicated. The failure appeared after I replaced the cylinder head gasket. What might have happened? I've already changed spark plugs, wires and even the rotor, but nothing got better.

Hi, joyce, by your diagnosis, it might be a low quality fuel problem. If it is so, use up what you've got and fuel the car with vi power diesel or premium diesel. Another possibility is that there is an electronic problem and you need to make an electric check: flowmeter or EGR valve. Hope it helps.

Typically, it would be due to a damage of the head gasket. For Diesel models, it could happen due to a seal failure in the oil cooler.
