Hi,
I have an odd issue with the PDC. I have front and rear parking sensors.
From time to time, and more often during wet days, my parking system stop working. Always, when I start the car, PDC is working, and as PDC activates on slow speed, I can tell it works for 2-3 minutes (I notice this when driving in town) and then I got continuous sound from front buzzer and the light in the switch stays on(no flashing), so I have to turn off PDC by pressing the switch. If I stop the car and start it immediately error is there, but if car stays off for about 30 minutes, PDC is working again, and it might work for a day or week and then develop the same scenario above. Sometimes in wet and cold days, I got error every day.
IID doesn't read any errors related to the PDC.
I remove the front bumper and loom seem OK.
All sensor are pulsing when do the pulse test. I checked the front sensors with multimeter and they have similar resistance.
What should I check next? Thanks,
Tiho

you need to read the live data of the 4 front sensors. Save them as favourites so you can find them when you are in a hurry.
A sensor not detecting anything will read 2.5m
A lower value is detecting something (or false detecting in your case)
When you get the problem, look at the live data, and I expect you will see one sensor reading a low distance value. Replace that sensor
