Default A4 vacuum leak

I have a 2007 a4 2.0 quattro. Check engine light code says vacuum leak. I replaced the gas cap. What should I look for next?

T, welcome aboard! Can you get someone to scan the car with VCDS? It'll provide more specific info. "Vacuum leak" is very generic.

had same problem with my 2006
after a gas fill up , do you get a 5 second delay ? like it takes few seconds to start the engine. ( just after the fill up, in the gas station)

if yes, then its the purge valve. a cheap and fast fix
good luck

I have a 2007 A4 b7 with navigation. The screen is out, but everything works. I am assuming the nav works too.
I have heard that if the screen is out it needs a fuse.Where is this fuse located?
