Twingo overheating radiator fan issue
Summary of the thread
A 2011 Renault Twingo diesel is experiencing overheating with the radiator fan not functioning, despite normal coolant levels and no leaks. The issue may be linked to a faulty speed sensor, which can prevent the fan from engaging properly. It is recommended to have a professional read the error code to confirm the diagnosis. Replacing the speed sensor resolved the overheating problem.

Thanks! Where is the speed sensor located, and can I check it myself with basic tools, or should I leave it to a professional?

It's probably best to let a workshop take a look. Get the error code read out first. If it says speed sensor like mine did, there you go. I ended up with about 250€ on the bill. Better than cooking your engine.

Appreciate the advice. I took it to a local mechanic, and you were spot on it was indeed the speed sensor causing the radiator fan to malfunction. Replacing it resolved the overheating issue. Thanks again for pointing me in the right direction!

I had a similar issue with my Twingo. Engine overheating and the same warning light. It was the speed sensor. When it fails, it can cause the fan not to engage properly. I would suggest checking it.
