I have a galaxy 1.9 tdi 53 plate I recently have had to change the radiator and water pump due to a blockage in the radiator. As I drove the car to the garage to be repaired it cut out 3 times (20 mile journey) due to over heating. Since the repairs the car seems to have no power in 3rd gear onwards, it will run at 70 to 80 ok on the flat but as soon as you ask anything of the engine it starts to shudder especially if you go up hill. The timing has been checked and is fine, the maff meter has been checked and is fine, I have had a new fuel pump and sender unit, all filters and fuel tank cleaned. Nothing shows up on the diagnostics and fords themselves seem to be at a loss as to what it can be but will do more checks if I keep paying them
