What exactly is a pcv, i got the black tubes on top, around the valve cover changed with the valve cover gasket change. Is that it? Thanks

The Passat has a complicated system of venting the interior pressure of the engine. Whereas other, older cars have a simple check valve, the Passat has multiple check valves, suction pumps, etc. Truly, modern German engineering at its finest!
Not only are there myriad parts comprising the positive crankcase ventilation system, they are not readily apparent or visible. The icing on the cake is that some of the hoses are fabric that doesn't live long in the heat of the engine compartment. The cherry on the cake is that they are installed with one-use clamps that are a PITA to remove. If you didn't pay about $400 in parts for all of the parts, then they haven't all been replaced (you can see the kits on ECS's website).

So what is there to do? Seems awfully kompliziert. Should i just have the seals and gasket replaced under warranty and hope that the new cap from ECS tuning is going to make the difference? Thanks

I can't answer your question. The car is ten years old. How long do you anticipate keeping it? How bad have the leaks become? What is the condition of the rest of the car?
I can't say if the newly designed cap is ultimately going to make any real difference - you might need to research this further online and see what you can come up with. I have no personal experience with it, but I plan to buy one for my Passat. I've got valve cover gasket and cam tensioner gasket leaks myself that I plan to address next Spring. I've had some of the pcv system replaced, but I'm not done yet.
Here's ECS's emissions webpage:
ECS Emissions Parts
Look at the bottom of the page - it shows what they have in a total kit (3 varieties, actually). This will give you an idea of what may have already been replaced when you had work done previously. If all of these parts were already replaced, then I'm at a loss as to what to tell you.

Thank you for your answer, the car has about 80000 miles, is in good shape overall, has been well maintained, the valve cover gasket has been changed 4 times, the cam adjuster seals 2 times, t was under warranty until august, vwofa tells me that the repairs done at the dealership are guaranteed 12 months 12000 miles, so i should get the leaks fixed under the nex warranty. I am going to look into the pcv system. Thanks

the dealership ended changing the breather and charged me only for the parts. about 140 $. Seems to have reduced the leaks. At least for now. But then the car developped some quirky problems, sometimes you turn it off and the lights stay on the dash board, you can only get them out by pressing the brake pedal, then the lights come again and you can't lock the doors with the remote unless you get back into the car and press the brake pedal again. Another thing that happens is when you switch off the ignition the engine sometimes keep running. Does it need to be reprogrammed? thanks
