There was a air leaking noise by my brake?

What is your question?

It was -11 today so started my car to warm it up when I came back to the car there was a sound on the drivers side by my feet like a air releasing noise. When I put my foot on the break it went away. What was that? Thanks

What makes this problem better or worse?

Went away when I put my foot on the break

How long has your 2016 Volkswagen Jetta had this problem?
