Hiace rain light sensor issue

My 2007 Toyota Hiace diesel, with 101336 km, has a weird rain-light sensor issue. Error’s stored, wipers won’t auto-wipe, headlights won’t come on, and even the speedo dimming’s gone bonkers. Lights are constantly switching on. I suspect it's bubbles forming under the gel pad on the windshield. Anyone seen this before?

Sounds familiar. I had similar gremlins in my '14 Skoda Octavia. The rain sensor went haywire and messed with other functions. I think the sensor calibration might've been off. Did you check this?

Calibration? Interesting idea! How did you check the calibration on your Skoda? Was it a DIY job, or did you need special tools?

I wasn't brave enough to mess with the calibration myself back then. I went straight to the workshop; they plugged it in, recalibrated it, and the problem was solved for a while! It was a known issue in some Skodas, I think.

I was hoping for a quick fix. Still, thanks for the insight! The gel pad was indeed the culprit. 62€ later, complete sensor change and now it's good to go!
