My Turbo is now 1 week old, and has 1100Kms on the clock. Today it started 'surging' whilst driving home. I have stopped and started the car a few time and it is still having. It only seem to happen between 2000 and 2500rpm - irrsepective of gear. Its an Auto, and ive tried it in Auto (Adaptive), Auto (Performance) and manual modes. It happens under power and when cruising - it doesnt happen all the time but comes and goes. The tacho pulsates when the power surges. It happens whether I use the cruise control or not. I have rung 3 dealers and Ford and noone has heard of it or even has any ides what it may be. It is booked in with a dealer for their night shift tomorrow. I have only used Optimax petrol.
