Hi I've got a 2007 s3 whilst fiddling under the bonnet the other day I noticed a random split wire and traced it to the n75 valve so I unplugged it and the other wire also came out so there is no wires going to the n75 valve. I'm not sure what the n75 does or if it can cause any problems with it not been attached. I'm going to buy a new connecter and wire when I can bought just want to know if driving it like this will cause me any problems as I drive it very spirited. Any help would be appreciated thanks
