I can see me doing this to mine this week I’m on my 2nd sensor and it’s still doing it! It’s bloody annoying And if Peugeot are saying to unplug it that’s a story in itself on them sensors..The same thing happened to me and I was instructed by Peugeot Dealer to unplug it. Apparently, even if you replace it with a new one same issue will re-occur.
Now I have unplugged it no more worries. But please ensure to wrap a tape around the unplugged parts for water protection. See attached photo below
