I think the stock bosch valve is around $60. It is a simple DIY job so labor should not be more than a couple tenths if you go that route. It could very well be functioning normally but I know that before I installed my Forge BPV, I could barely hear any kind of noise coming from the valve.
The valve is located at the front of the engine and is connected to the black tube running from the intercooler to the throttle body. It is a black part with two tubes coming from it, one attaching directly to the black tube I just described and the second pointing side to side in the engine bay and connecting to the silver pipe that runs back to the intake pipe which is gray and goes up and down between the turbo and the intake. Check the direct connections to the valve...these should be clamped down securely. Also check your intake and air box to make sure everything is connected properly. Make sure your air filter is sitting in the proper place with the plastic prongs sitting inside both sides of the filter.
