Jumpy auto lights wipers faulty sensor

My 2008 Citroen Jumpy with a diesel engine has auto lights and wipers that are playing up. The rain-light sensor seems fried. I'm getting an error, no auto wipers, no auto headlight control, and the speedometer dimming isn't working! Sometimes the lights just switch on for no reason. It's only done 51099 km, what gives?

I had similar issues with my Jumpy. Does the windshield have any bubbles under the gel pad where the sensor sits? It's a common problem and messes with the sensor's readings.

Bubbles, eh? I'll have a look. If there are bubbles, is that definitely the culprit? What did you do to fix it?

In my experience, yes, the bubbles are the likely cause, as they affect the sensor calibration. Unfortunately, I'm not qualified to fix such a problem, so I recommend taking it to a workshop.

Had a look, and you're spot on – bubbles galore! Took it to a shop, they confirmed it. 62€ later, and it's sorted. New gel pad, recalibrated, and everything's working sweet again!
