These sensors are fitted across many PSA vehicles - including the C4 Picasso and the later Spacetourer models so should be the same.

I don't post anything out - it's all above ^ in the guide, as respectfully, this is a Forum and not a mail order service :-D

Just out of interest, I've taken the door card out as per the guide, was working my way through dismantling the mirror...when I found one of the temp sensor wires was cut inside the mirror.

So joined it back up and it's apparently working. So my question is, can anyone think of a reason someone might have done this?

Maybe somebody had accidentally cut it previously when trying to replace it and gave up leaving it as it was!

Yeah hopefully, just wondering if it's tied into any other parts of the ecu. Ah well will suck it and see. Fantastic guide though, absolutely invaluable!

Apart from the outside temperature display, the temp sensor is also used for the correct operation of the Air Conditioning / Climate control systems. So it will be used by the BSI and the Climate control ECUs
