What does this fault code mean?
The power consumption of hall sensor 15 deviates from the normal values both when it is on and when it is off. This may be caused by a damaged hall sensor or by an internal fault in the roof control module. The roof may then be operated only in a limited way or not at all.
Possible causes
- Damaged hall sensor
- Internal fault in the convertible roof control module
What you can do
- 1With the ignition on, look for wear and signs of damage on hall sensor 15.
- 2Check that hall sensor 15 is held firmly and that its connector has not come loose.
- 3If there are signs of damage, have a workshop replace hall sensor 15.
- 4If the fault remains after this, have a workshop fault-trace the roof control module, as the fault is then probably internal.
Symptoms you may notice2
- No or limited roof operation
