2008 a4 2.0 engine check lite is on, initial diagnostic chk. indicates evap. system , what should be chked ? Tried opening & closing gas cap

Hello and thank you for your question,

In most cases Evap system fault codes are due to a Evap sysyem leaks and in most cases the best way to find them is to do a smoke test on the Evap system . Unless you have access to a smoke machine then this is something your going to have to done by a repair facility. Once the smoke machine is connected the leak can be readily found and repaired.
