How to empty the fuel filter on a diesel engine from Mercedes 350sdl (turbo)?

I think I have a problem with water in my fuel diesel. I drain the fuel filter because it is the use of water there. When under the hood? I have this strange problem when my car stalls at times completely out of messaging instant, while a red light (stopped). The radio stays on, but the engine died. My Idle speed is fine and I'm pretty sure your problem fuel supply, and someone suggested it could be water tanks in the fuel. I have this thing called ISO-HEET you put in your tank before filling, it is assumed that breaking the water and allowed to leave the tank. Anyone using this material? Some people told me not to use additives in a Mercedes, but I do not see anywhere where in the manual, and it seems that if it does what it says, would help. I also had the Diesel Kleen + cetane boost things - anyone use this? But back to the main question, how do I empty the diesel fuel filter? thanks

the son of a short circuit leaving the juice injection pump without solenoid injection pump or the idle should increase. The other thing you should look restricctions is to air in the air intake manifold. No Use more cleaner and more in a diesel engine .... period or from fluids. or additives.
