What you can do
- 1If fault code CRM-C032 is stored, deal with it first, as this code is not detected while it is present
- 2Read out and clear the fault code, then test the roof in both directions and see whether the fault returns
- 3Look for objects or damage in the roof's travel area that could stop the roof
- 4Check that the sensor is firmly fixed and that the connector is free from corrosion and loose contacts
- 5If you have a diagnostic tool, follow the sensor position in live data while the roof moves and check that the value changes
- 6If the fault remains after these checks, a workshop needs to replace or test the hall sensor
