Hi everyone sorry if i have posted this in the wrong place. I have an Audi A4 1.8t 1998. I have been reading up on the BOV/DV and was recently given a forge BOV/Recirc valve that is advertised for this car. I went to try and fit it and got myself all confused. Can someone please tell me how to fit this. It is a forge valve with an intake port and an output port (im guessing) with a nipple for a vacuum hose on the top. on the top there is also a dial that turns to open up 4 small holes. When I took the original valve off I couldnt see a vacuum hose that would connect to the top of the Forge. Can someone advise me of where I am going wrong or how to fit it. I have checked the rest of the forum and couldnt see any part that covers my problem. (or maybe I am just a bit of an idiot lol). Thanks in advance
