The throttle body on an engine houses the throttle, which controls the amount of fuel that enters the engine. It controls the engine's ability to maintain an idle, prevents stalling, and aids in acceleration. If the throttle body is dirty, it can cause problems with the engine running properly. During a standard service, sludge and carbon buildup out of the throttle body and off the throttle blade. The vehicle's computer is then hooked up to a special machine for an idle relearn procedure.
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.
This is a dirty throttle body. Very common on our trucks.
