If Fabia 1.4 16v engine code AUB then suspect piston ring fault. Check if car is using excessive oil. Combustion gasses will be blowing by the piston rings and into the crankcase. Oil vapour is then blown up into the air intake and into the throttle body, throttle body will be dirty. Can occur on very low mileage cars.
