Mondeo with a mind of its own I bought my Ford Mondeo 1.8 TDCi new in September 2009. From the start I noticed sharp acceleration when I let the clutch up after changing from first to second. I put up with this, thinking it might be a characteristic of diesels, but the problem persists. The car literally jumps forward when the clutch is let up, but Ford dealers can't pinpoint any fault. I have to be very careful not to hit the car in front when changing from first to second and I constantly drive with the clutch pedal half down, which can't do it any good. Any ideas? This is an old engine based on the original 1983 Fiesta diesel and has now been dropped in favour of a newer 1.6 diesel. One example managed 1,000,000 fairly trouble-free miles in a Mk1 Mondeo, but it does have characteristics. It has a high idling speed (1,000rom) and the engine won't run below that speed. If 1,000rpm corresponds to more than the speed you want to go in second gear, there will be a "jumping" sensation as the speed of the car rises to match that of the engine.
