If its just the speedo failing and the rev counter works ok, its likely to be the speed sensor which is on the gearbox. This will have to be removed as soon as possible to avoid engine damage! Expect to pay about £30-40 not £128 like some have paid from a Ford dealer.

The speed sensor as well as talking to the speedo to say how fast youre doing also talks to the fuel pump and adjusts the amount of fuel to send to the engine according to the speed your doing. So, if it thinks youre doing 0mph, it will supply a minimum amount of fuel and is likely to stall when slowing down. You might notice a lack of power whilst the speedo is failing as its starving the engine of fuel, causing it to run a lean mixture, which also burns hotter and could overheat and damage the engine.

yes there is a know problem with the fuel system. fuel pump breaks down, empty your fuel filter into a bowl and check for metalic, if you have this in the filter your pump is F..... along with all the other common rail stuff. expensive job... error codes though, i find that hard to believe, fuel pressure faults will occur, i think you garage does not know what to do. or does not want to tell you the cost of the job and he will be in doubt himself of wether he is right..... was you engine coil light flashing at any point.!!!
