Hi folkes on what seems to be my never ending search for my octavia's fault. When the car went in to skoda on the recall for coil packs they ran a diagnostics check and the 'afm' fault came up so I have replaced this today and stlill have the problem of juddering and flat spots do I need to get the computer to reset my car now I have replaced the part ? Any help as always greatly appreceated :-)

Did you replace it with a genuine Skoda/Bosch part or an aftermarket one? The throttle body may need cleaning too.
