Optra rain light sensor malfunction

I've got a 2022 Chevrolet Optra with a gasoline engine, and I'm running into a weird issue. My rain-light sensor seems to be acting up. I'm getting an error stored in the error memory, and the automatic wiping mode in the rain isn't working at all. Plus, the automatic headlight control is kaput, the speedometer dimming is out, and the lights switch on by themselves. I suspect bubbles might be forming under the gel pad of the windshield. Has anyone else encountered anything similar? Mileage is sitting at 225576 km. Any thoughts?

A 2022 Chevrolet Optra owner experienced issues with the rain-light sensor, leading to malfunctioning automatic wipers, headlights, and other related features. The problem was suspected to be caused by bubbles forming under the gel pad of the windshield. The solution involved replacing and recalibrating the sensor, which resolved the issues.

That sounds like a faulty rain-light sensor indeed. Does the error code point specifically to that sensor?

Yeah, the error code does point directly to the rain-light sensor. I'm just trying to figure out if it's a simple replacement job or if there's more to it. Is there any calibration needed afterwards?

Given the error code and symptoms, the sensor itself is likely the culprit. Calibration might be necessary after replacement. You could try replacing it yourself, but a workshop visit is advisable to ensure proper coding.

Thanks for the input! Turns out it was indeed bubbles under the gel pad as suspected. Got the sensor replaced and recalibrated at the shop. Cost me 62€, but everything is working fine again.
