Check valve replacement issue

Recently i found 3 vacuum leaks.....vagcom dialed it out to be the check valve. Now the stock check valve has 4 hoses that join onto it. I ordered another replacement check valve and hose kit (because its all one unit) and it only came with 3 hoses attached to it. The dealer said thats its an updated part and i would need to block off one of the hoses, but wouldnt that make an engine light stay on???
Has anyone had to replace this? And if so, what hose gets a cap on it?
