Hi all, my brothers A1 (11 plate) seems to have an annoying intermittent problem in that the power just drops off at unpredictable times - Mostly when accelerating but occasionally whilst cruising along. The effect is that the engine is 'holding back' - like maybe the turbo is cutting out? Disconcerting when you pull out to overtake & suddenly lose power. It only seems to happen once the engine is fully warmed up, never when it's cold.
Mystifying. Anyone have an idea??
