Hello, I have an 06 plate TDi Auto, this intermittently experiences a loss of power whilst driving. If you stop the vehicle, wait several seconds and restart the problem has gone. Seemed to happen when I first had the car, this time last year, then seemed to go away. Now it has done it several times recently. Possibly related to the colder weather? No engine lights come on to indicate a problem, the car is still under FordDirect warranty, they have 'checked' it twice but can find no fault, as it only manifests itself intermittently I can understand why this might be difficult. To the original poster, is your problem always there or intermittent? Regards, Richard
