Twingo Rain Light Sensor Issue

I'm pulling my hair out here! I've got a 2011 Renault Twingo diesel, with 86412 km on the clock, and the rain-light sensor is acting bonkers. I'm getting an error stored in the memory. Basically, the auto-wiping is dead, auto headlights are useless, even the speedometer dimming is off, and the lights just switch on whenever they feel like it. Anyone else seen this kind of madness?

Sounds familiar. I've got a Twingo too, and had similar gremlins. Check for bubbles forming under the gel pad where the sensor meets the windshield. It messes with the sensor readings.

Bubbles under the gel pad, you say? That's a new one on me. Is that a common thing? And does it really throw off all those systems?

Yep, bubbles are the likely culprit. They cause all sorts of mayhem with the sensor signals, affecting the wipers, lights, and even the dash dimming. Best bet is to get it checked at a workshop.

You were spot on! Took it to the shop, and you wouldn't believe it – bubbles galore under that gel pad. They replaced it, and everything's back to normal. Cost me 62€, but worth every penny. Thanks a bunch for the heads-up!
