before you replaced the sensor, would your AC light turn on or shut off after you pressed it? When I press mine it shuts off right now

[@MYCARSSTORIES]

Yes, I had the same symptoms, sometimes on, sometimes turned off. But be careful with link in description, one link is bad sensor, other link is ok sensor

[@MYCARSSTORIES]

As I said, yes, same symptoms, also caused 00256 error. Dealer stated that the problem in sensor

Check fault codes with vcds or OBDELEVEN. In this video I’ve showed 0256 error. But it also could be wire damage and so on

[@armandasvaitekonis1042]

I broke the new sensor inside. So upset right now. Any idea of how the whole housing is called so i can order a new one? Or do i need a whole new radiator 😂
