I have an 07 galaxy 1.8tdci which in my opinion is not right! At low engine speeds performance is very sluggish and there sounds like diesel knock when acclerating. After this initial lapse, the car pulls fine with no problems. Took to main dealer who advised/road tested and said it was fine. the car has no warning lights on or faults in ECU memories!

Has anyone else experienced this or have any ideas?

Thanks in advance
