Was bedeutet der Fehlercode?

Position sensor 2 and position sensor 17 indicate positions that do not match each other. The convertible roof module (CRM) therefore cannot reliably determine the roof position. The cause may be a damaged or displaced sensor, or a protruding metal part wrongly activating a sensor.

Mögliche Ursachen

Damaged position 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
2Make sure the position sensors are firmly fixed and that their connectors are clean and free from oxidation
3Look for damage to the roof that could make both sensors signal at the same time
4If you have a diagnostic tool, follow the status of both position sensors in live data while the roof moves forward and back
5If a sensor is damaged, a workshop should replace it and calibrate the roof afterwards

Symptome, die Sie bemerken können1

No or limited roof operation
