excess road dirt on back of trunk deck
 

[align=left]hi.. new audi owner, a4, cabriolet, 2006. i notice that the back of the trunk lid and rear bumper is covered in road dirt/dust immediately after washing and driving on the highway. rear licence plate recess seems to collect the most dirt.[/align][align=left][/align][align=left]is there some known airflow/turbulance issue with the body design that causes this? anybody else seen this?[/align][align=left][/align][align=left][/align][align=left][/align][align=left][/align]

driving with the top down it becomes more drastic but the rag top creates the turbulance.

air flow directs it there, my car will be spotless, and the back will be covered in dirt[:@]
