Hello 😉.

Is it possible to adjust the sensitivity of the rain sensor via Lexia?

If not, what else could be done to make it less sensitive?

You would need to check if it can be made less sensitive at a dealer but I could not find anything in Citroen's service box procedures that suggests a diagnostic is used if the sensor is replaced. If there is any dirt on the sensor area of the windscreen or on the sensor then that might make it seem more sensitive.


On our 2007 C5 the sensor does not seem sensitive enough since it takes too long between intermittent windscreen wipes when on auto, maybe I could try putting dirt or some tape over it.
