V50 Water Sensor Fault

I have a V50, but with a petrol engine, and had a similar sensor issue recently. Check the cable and plug connections to the sensor first. A bad connection can cause those symptoms. Has a garage looked at it?

Thanks! Which sensor was the problem on your V50, and how did you find the bad connection?

It was the water sensor on my car too, triggering the malfunction light. I didn't figure it out myself; the workshop found the defective connection and fixed it.

You were right! It was the cable connection to the water sensor. The workshop confirmed it, replaced the corroded connector, and it's running perfectly now. Total cost: 95€. Thanks!
