    What is it?
    Where is it located?
    Is there anyway of testing it?
    Are they expensive?

    Its located at the rear of engine bay in the plenum where fresh air goes into car. It is meant to detect hydo carbons in the air.
    I have my doubts they ever make the flaps close. Meant for looong Euro tunnels.
    You can ignore it.

    I had the same fault with my 8P1. yes it is locatated on the front edge of the splash panel for the ventilation air intake. Which is the under plastic cover at base of windscreen. part no. on mine is 4B0 907 659A.
    I took mine out and sprayed the sensor with brake cleaner. Now fault code is cleared. Guess mine was just dirty
