citroen c3 outside temperature sensor Problem
Hello friends, I'm writing from Türkiye. I have a 2011 Citroën C3. I enjoy driving it. Today, my outside temperature sensor malfunctioned. It's showing various inaccurate values. I couldn't find the sensor directly in Türkiye. Could you tell me the correct part number? VIN code: VF7**************[VIN obfuscated, can be read by forum staff]

There may be more than one outside temperature sensor. Where is the one you are talking about fitted? 
I used to be indecisive, now I'm not so sure!

I'm surprised. I don't know exactly where it is. According to the information I got from the internet, it's in the right mirror.mickthemaverick wrote: 12 Oct 2025, 20:02 There may be more than one outside temperature sensor. Where is the one you are talking about fitted?![]()

Then I can look it up for you in the morning, as my system is not available at the moment. I'll need your engine type and gearbox type as well as your RPO number to be accurate as I only have access to a backup system. I assume it is the sensor in the underside of the passenger door mirror.

Thank you so much for your help. I'll order from Aliexpress. It will take up to 30 days to arrive in my country, including taxes and other factors. I'll post the results.
