Seat Ibiza Diesel Water Sensor Issue

I am writing to report an issue with my Seat Ibiza, model year 2007, equipped with a diesel engine and currently at 130722 km. The malfunction indicator lamp has illuminated, and the engine exhibits rough running characteristics. Based on preliminary investigation, it is suspected that the water sensor is malfunctioning, potentially due to a defective cable or plug connection. Has anyone experienced similar problems with this car sensor?

I have encountered similar symptoms with my Ibiza. Check the wiring harness and connector for the water sensor. An electrical fault in that area is a plausible cause.

Thank you for your suggestion. Could you please elaborate on the location of the water sensor and the specific wiring you inspected?

The water sensor is typically located near the fuel filter. In my case, the electrical fault was indeed within the connector itself. Replacement of the connector resolved the issue. Considering the symptoms you described, a professional workshop visit might be worthwhile.

I appreciate the insight. Following your advice, I performed car diagnostics and the error memory indicated a water sensor malfunction. Upon inspection, the cable connection exhibited signs of corrosion. After replacement, the issue seems resolved. The malfunction indicator is off, and the engine is running smoothly again. Total repair cost amounted to 95€.
