Reversing sensors and temperature

I have had my 2008 D4D VX for about 18 months. I have noticed over the last 6 months or so that the parking sensor speaker is beeping when in reverse if the temperature is cool. Hotter days, the sensor speaker does not beep.

This is happening without any towball or treg hitch on the tow bar tongue and even without the towbar tounge in the towbar.

Anyone else have a similar problem? Have just searched the forum and will try the on/off switch near the speaker to stop the beeper temporarily but need to work out why it is happening. Don't want to turn the beeper off forever.

There are posts in here commenting on the sensors. I reckon they are next to useless especially compared to others I have used. The sensors don't like being wet or dirty or sometimes the day of the week or the colour of my undies. My advice is don't rely on them. My wife managed to reverse into a short post right on top of one sensor. Which went 'beeeeeep' as the car stopped. The sensor tested perfectly. $1500 later it looks ok again.

Have tried cleaning the sensors but doesn't do anything either. Have not noticed if colour of undies a cause but will keep an open mind on that. Maybe because I wear shorts in hot weather and jeans in cold weather..
