Skoda Kodiaq diesel engine sensor issue

The symptoms you describe certainly point towards a sensor issue, specifically with the water sensor. Given the mileage and the age of your Kodiaq, a degraded connection is plausible. Have you inspected the sensor's connector for any signs of corrosion or damage? Sensor testing, even with a multimeter, can be tricky without the proper schematics for your specific engine. An electrical fault can manifest in many ways, so a systematic approach is crucial. Do you have access to a diagnostic tool that can read live data from the sensor? This could help pinpoint the exact nature of the malfunction.

Thank you for your response. I have visually inspected the connector, and while I didn't see any obvious corrosion, I don't have the tools for proper sensor testing. Could you elaborate on what kind of live data I should be looking for with a diagnostic tool and what would be considered normal values for a water sensor?

Considering your limited access to specialized tools and the potential for misdiagnosis, I would suggest taking your Kodiaq to a workshop equipped with the appropriate diagnostic equipment. The described behavior does suggest an electrical fault related to the sensor. A proper diagnosis will save you time and potentially money in the long run. The predicted repair cost of 95€ for the cable or plug connection seems reasonable.

I appreciate the insights and the suggestion to have it checked professionally. As it turns out, the cable connection to the sensor was indeed faulty. The repair cost 95€. Thank you for pointing me in the right direction!
