Thalia Washer Fluid Sensor Issue

Thanks! Where is that wiring harness located? I'm not familiar with car electronics. Is it easy to get to, or do I need to remove a bunch of stuff?

The wiring harness should be directly attached to the washer fluid reservoir. In my case, the issue persisted even after I checked the lines. Given the car’s mileage and the persistent error, a diagnostic scan at a workshop is recommended to rule out a faulty washer pump or a more complex electrical problem. You might spend a lot of time and energy without fixing this on your own.

You were right! The shop found a faulty sensor. They replaced it, and now it's working perfectly. Cost me 25€ all in. Thanks so much for the advice!

I had a similar issue with my Thalia. The error memory stored the same error. If the reservoir is truly full, the sensor might be faulty or disconnected. Have you checked the wiring harness connected to the washer fluid reservoir? Sometimes these become loose or corroded, causing false readings.
