What does this fault code mean?
The code is set when the sun roof control module registers an internal fault. The motor then runs and the sun roof moves even when the relay is not switched on. The electric sun roof does not behave as it should.
Possible causes
- The sun roof motor runs and the roof travels although the relay is off
What you can do
- 1Note whether the sun roof moves by itself when you are not operating it.
- 2Read off the code and clear it.
- 3Check that the sun roof can be operated with the switches.
- 4If the fault remains, have a workshop replace the sun roof motor and, if needed, the control module.
Symptoms you may notice1
- The electric sun roof does not work
