Was bedeutet der Fehlercode?

Hall sensors 18 and 19 report positions that do not agree with each other. The convertible roof module (CRM) therefore cannot rely on the roof being in the correct position. The cause may be a damaged sensor, a sensor that has moved, or a protruding metal part wrongly activating a sensor.

Mögliche Ursachen

Damaged hall sensor
A sensor has shifted from its position
A protruding metal part wrongly activates a sensor

Was Sie tun können

1Read out and clear the fault code, test the roof and see whether the fault returns
2Make sure hall sensors 18 and 19 are properly fixed, and that their connectors are clean
3Inspect the roof for damage that could cause both sensors to signal at the same time
4If you have a diagnostic tool, compare hall sensors 18 and 19 in live data while the roof is running
5If a sensor is damaged, a workshop should replace it

Symptome, die Sie bemerken können1

The roof cannot be operated, or only to a limited extent
