Was bedeutet der Fehlercode?

Hall sensors 18 and 1 report positions that do not agree. The convertible roof module (CRM) therefore cannot reliably determine the roof position. The fault can be caused by a damaged or displaced sensor, or by a protruding metal part wrongly activating a sensor.

Mögliche Ursachen

Damaged hall sensor
A sensor has moved out of position
A protruding metal part wrongly activates a sensor

Was Sie tun können

1Read out and clear the fault code, then test the roof to see whether the fault returns
2Check that hall sensors 1 and 18 are fixed in place and that their connectors are free from oxidation and play
3Look for damage to the roof that could make both sensors activate together
4If you have a diagnostic tool, follow the position value of hall sensors 1 and 18 in live data while the roof runs
5If the sensor is damaged, a workshop may need to replace it

Symptome, die Sie bemerken können1

The roof cannot be fully operated
