LandCruiser rain-light sensor fault

My 2010 Toyota LandCruiser with a diesel engine is showing a rain-light sensor fault. Symptoms are an error stored in memory, no automatic wiping in the rain, no automatic headlight control, no speedometer dimming, and the lights switch on. Mileage is 106206 km. Any ideas?

I've got a LandCruiser too, and that sounds familiar. Did you check for bubbles forming under the gel pad of the windshield around the sensor?

Bubbles under the gel pad? What does that mean?

Yeah, those bubbles can mess with the auto sensor. If you see them, it's likely the culprit. You may need a workshop to sort it properly.

Thanks for the suggestion, it was indeed the bubbles. Workshop replaced the gel pad. Repair cost was 62€. Issue resolved.
