Help needed please. I am driving a clk 270cdi on a 03 plate, yesterday when I took the car out I noticed it was a little difficult to get in gear then when I came to my motorway junction I pressed the clutch pedal and there it stayed. Last November I had a new master cylinder fitted so my initial thoughts are that that is ok. About a month ago I did notice a pool of fluid that seemed to come from the mud flap on the drivers side, I checked all the fluids and everything was ok and it has driven fine since, I really don't know if that has any relevance. It is obviously an hydraulic problem but I can't understand if it is a split pipe or broken seal why my resevoir is at the correct level! Any thoughts or ideas would be greatly appreciated.
