I picked up my 1.8t yesterday and wanted to change my air filter over from my 2.0 gti.
So I undone the two screws that secure the lid shut and unhooked the top cover. Took out old filter and popped in the new one . But when it came to putting the lid back on it just didn't seem to sit flush on the side where the hinges are. There's not a huge gap but I was just wondering if it has to be a sealed unit or will it be ok to stay like this.
