MODELS 163, 168, 171, 203, 209, 211, 215, 220, 230 with CODE (345) Rain sensor
Due to the physical principles governing its function, in a few situations the rain sensor may trigger a wiping cycle when this is not actually necessary (this does not pertain to the initial wiping cycle).
This behavior may occur under the following conditions:
- Strong transitions between light and shadows (due to the position of the sun and the season of the year)
- Insects on the windshield in the area monitored by the sensor
- Fogging of the glass when entering a tunnel or garage
In such cases, an exchange of the rain/light sensor is not justified and will not remedy such problems. | |||
1 | Determine whether errors occur. | ||
2 | Inform customers about the technical boundary conditions affecting operation of the sensor | Inform customers of the option of leaving the steering column switch in "0" position during longer dry periods in the summer (no operation of the rain sensor). |
