this is exactly the same problem i have with my skoda fabia comfort 16v and it seems like a never ending problem for me,i took mines to the dealer ,they did the diagnostics nd told me it was the EGR valve nd i got it replaced for a mammoth £300 nd still the car has the same actions aswell as the engine management light cumin on at times nd then goin off.Just last week i called the AA down to do a diagnostics nd it sed code P0322 which was sumit to do with the ignition distributor so i changed the crank sensor aswell as the coil pack nd guess what it still does the same old things! it realli is annoyin me ,but if i can get it sorted i will defo let u kno
