What does this fault code mean?

The ECM runs a learning routine for the swirl damper position, and the code is set when that routine is judged incorrect. It can also be set when the damper reaches its position too slowly and deviates from the calculated position. The learning is checked with the engine switched off, while the comparison with the calculated position is made with the engine running.

Possible causes

Linkage or swirl damper sticking
Damaged linkage between the swirl throttle motor and the swirl duct
Swirl throttle motor sticking
Defective swirl damper motor

What you can do

1Check whether the arm between the swirl motor and the swirl duct has come loose
2Check that the linkage and the swirl duct move freely and are not damaged
3Check that the swirl throttle motor is not sticking and is not damaged
4If you have a diagnostic tool: read the swirl damper position in live data with the engine running and check that it follows the calculated position
5Clear the code only once the mechanics have been checked, then see whether it returns
