What does this fault code mean?
The audio control module (AUD) monitors the temperature at a transmitter diode in the MOST connector, which is part of the fibre-optic data bus. When the temperature gets too high it records an internal fault and often shuts itself down. The usual causes are high ambient temperature, high power draw or a damaged module.
Possible causes
- Excessive ambient temperature
- High power consumption in the module
- Damaged audio control module
What you can do
- 1Let the car cool down and see whether the sound returns
- 2Make sure air can circulate around the audio unit and nothing is blocking it
- 3If the fault only appears when hot it may be temporary overheating, but if it recurs the module needs replacing
- 4A permanent fault means the audio control module must be replaced by a workshop
