Its normal dude, im a vw technician. Seeing as you added this years ago id imagine you already know that! Engines have a crankcase ventilation system to stop the build up of crankcase gases the ducting on top of the engine takes it into the air inlet and burns it off! If you take the cap off running its gonna make a mess! Pretty much all cars do that tbh. If it blows past the cap when its on that's an issue, blocked breather etc
u need "Wynns EGR Valve Cleaner" take the Air Hose off (at the EGR valve end) - start her up, (shock horror! yes, start the engine with the air hose disconnected) spray all of the can (short 2 - 5 second burst) into the inlet. I've done it, returns power to the engine, EGR re-circulates carbon rich exhaust gases back through the combustion chamber to allow it to be burnt a 2nd time, reducing black smoke out the back, hence the fumes out the oil filler cap, tis normal for this engine :)
