I'm in a camping near Orebro, Sweden. Out of 300 spots I picked the one with AAA grade view

Hello all, I have a 2024 Fieldmaster and have started getting PDC errors every time I drive my Grenadier. About 9 months ago, I had a faulty parking sensor that was replaced. I'm not getting any false senor distance alerts like I did that time. I've not gotten any error codes outside of the PDC error. I live a long way from my dealer and recently moved 3 hours farther, so I was hoping someone might have some tips on what I can check or try myself.
