What does this fault code mean?
The power consumption of hall sensor 6 deviates from the normal values both when it is on and when it is off. The fault is caused by a damaged hall sensor or by an internal fault in the convertible roof control module. The roof may then be operated only in a limited way or not at all.
Possible causes
- Damaged hall sensor 6
- Internal fault in the convertible roof control module
What you can do
- 1With the ignition on, check that hall sensor 6 is held firmly and is not loose in its mounting.
- 2Look at hall sensor 6 for wear and signs that it has stopped working properly.
- 3If you have a diagnostic tool: read hall sensor 6 in live data while the roof runs, and see whether the value switches between on and off.
- 4If hall sensor 6 is damaged, have a workshop replace it. If no fault is found on the sensor, have a workshop fault-trace the roof control module.
