Remove the air filter. The air intake from the inner wing into the airbox is usually loose and vibrates, particularly in cold weather. A couple of strips of duck tape to hold the intake rigid will cure it for a year or so.

The noise you are getting when changing from 1st to 2nd is the turbo waste gate. This is nothing to worry about and is very normal on Avensis from late 2006 onwards. Mine has 515,000 km and is very reliable.

Think it is to do with a pipe at the air box; a rubber mount wore down, and just replaced it with insulation tape; not a sound now.
