Peugeot 106 Water Sensor Fault

Sounds familiar. I had almost the same problem with my old Opel Astra - the malfunction indicator was driving me nuts. Is the sensor easily accessible in your 106, or is it buried somewhere deep?

The sensor looks pretty easy to get to, near the fuel filter. But I don't want to mess with it too much without some advice. Did you fix the Opel yourself, or did you take it to a shop?

I tried fiddling with it myself, but eventually, I gave up and took it to a workshop. Turned out to be a faulty connection, just like you suspect. Saved myself a headache in the end.

Good to know. I'll probably take my Peugeot to a mechanic I trust. Hopefully, it won't cost too much. I got a preliminary quote of around 95€, which seems okay. Thanks for sharing your experience; it really helped.
