what is trouble code P-2008?

http://www.autocodes.com/p2008_volkswagen.html

The P2008 Diagnostic Trouble Code refers to the intake manifold runner flap control. Modern engines have flaps that change the effective length of the intake runners (how far the air travels between the throttle and the intake valve) to increase the efficiency and the performance of the engine. When the intake runner flap control fails (or is jammed or is disconnected), a code is set in the engine control module to alert you to the failure. You should have this system checked to see what is wrong.
