159 parking sensors/ambient temperatures

Good evening all.
I know there are many posts on 159 parking sensors but has anyone had experience of them playing up due to temperature change?
Mine have played up for about three years in cold weather, but as soon as the ambient temperature hits around 25C, they start working again, with no error message flashing up.
As soon as it cools down, the fail again.
This summer however, they have been more 'friendly' and working at a lower temperature.
Has anyone had the same experience, or can offer a suggestion?

Cheers.
Norro.

had one on my brera thatd only work when the car had been running for a while. it was directly above the exhaust, so i came to the conclusion that the heat from the exhaust was making it work, so its the same sort of situation as yours.

replaced it in the end
