Vacuum Check valve location?

So I'm going to replace my vacuum check valve as I think it might be part of the problem for my starting issues, I found some on eBay for about $10, but where is it located? It's a 98.5 A4 1.8TQ

By the airbox. Take off the top cover and it should be near the back of the airbox.

There are an additional 2 check valves near/under the intake manifold. And there's a slightly larger black check valve at the back of the intake manifold for the brake booster.
