Sorry, I searched for sometime this morning and only found comments related to using an optimiser but nothing definitive.
There was only a list of text codes from the dash display (owners manual) but nothing resembling your error message.
I'd keep an eye on your battery voltage and maybe check around your Earth connections?
Good luck - Frank
