What does this fault code mean?
The audio control module (AUD) has registered that a button on the left headphone panel has been held pressed for too long. This suggests a function button has jammed in the depressed state, so the control is ignored. As a result the headphone buttons and the headphones may not work correctly.
Possible causes
- One or more function buttons stuck in the pressed position
- Faulty button
What you can do
- 1Check that the buttons on the left headphone panel spring back and are not jammed
- 2Make sure no object is pressing on the buttons
- 3Clear the code and check whether it returns; if it does, investigate the buttons
- 4Have a workshop replace the headphone panel if a button sticks again
Symptoms you may notice2
- The buttons for the headphone output do not work
- The headphones do not work
