The error code points directly to a malfunctioning rain-light sensor. Could a faulty sensor cascade into affecting seemingly unrelated functions like the speedometer dimming? Trying to ascertain the root cause before replacing anything.

Yeah, if the sensor is feeding bad data into the car's computer, it could definitely mess with other systems that rely on light/visibility info. I'd say get it checked properly before ripping out sensors and spending a fortune. Best to get a proper diagnostic.

Insights confirmed my suspicions. A technician found bubbles under the gel pad obstructing the sensor. A replacement sensor, costing 62€, resolved the issue. Thanks for confirming my diagnosis!

That sounds like a pain. Bubbles under the gel pad? Never heard of that specifically. But if it's messing with the rain sensor, it probably throws off the whole auto-lighting system since they're usually linked. Does the error code point specifically to the rain sensor or anything else?
