What does this fault code mean?
The roof control module has registered that the position sensor in the front roof section shows a position that does not match the expected one. The voltage to the sensor is also outside the approved range. The roof can then be operated only in a limited way or not at all. The fault is caused by a damaged or incorrectly fitted sensor.
Possible causes
- Position sensor not working
- Position sensor incorrectly fitted
What you can do
- 1With the ignition on, test the roof in both directions. See whether it stops or moves unevenly.
- 2Check whether the position sensor is worn or damaged, and whether it moves freely in its position.
- 3Check that the position sensor is correctly fitted and secure.
- 4If the sensor is damaged or incorrectly fitted and cannot be corrected, have a workshop replace it.
- 5After the work, check that the roof can be operated in both directions.
Symptoms you may notice1
