Hi all,
I got my 2023 Formentor e-hybrid in June and after few days i noticed battery error. But after stop/start cycle it went away for a while. Over last few weeks its coming up again. Its not changing anything, everything works ok. Anyone came across that error?
What is the cause?

Thanks

It's the first time I see this error message in 3 years of Formentor PHEV usage, but I would say the pictogram next to that error shows the 12V battery. It's worth a 12V battery test if your car is 3+ years.
 
Is this error coming up while driving, or while the car is stationary and some accessories are used (ventilation, audio etc.).
I'm asking because the 12V battery should charge while driving (either in hybrid mode or in pure EV), and while charging the HV battery. Are you regularly plugging the car to charge the HV?
