External sensor and AC problem. Possibly TPMS as well?!

Unread post by jcknowles »

Hi

On our DS3 the external sensors was reading very low (-25 to -30). Also the AC wasnt working. Also TPMS was giving errors for all 4 tyres. Took it in to be regassed for the AC and the engineer said the compressor wasnt coming on.

After a bit of online reading I thought it might be due to a broken external air temperature sensor. Changed it and it seemed to be reading a better air temperature, although it was still wrong (reading 10C instead of 20C). Subsequently the temperature reading went back down to -25 to -30.

Does anybody have any ideas what might be the cause of this? Is there a central control unit that might be the source and where is it located?

Thanks!

Where did you get your replacement temperature sensor from?

Hi. Thanks for the quick reply. From ebay. Is it likely to be a cheap part? Should I have got a genuine one?

Thanks again
