What you can do

- 2Follow the signal wires between the module and the speaker in the left front door and look for damage
- 3Use a multimeter to check that the signal wires are not broken or short-circuited to each other or to ground
- 4If no wiring fault is found, have a workshop check the module and replace it if needed
- 5After the work, clear the fault code and check that it does not come back
