At the price some charge for it…!!!I think the manual said it’s either Holy or Perrier..I forget which
Deionised is the standard option, distilled is more exotic but ok, BMW states that tap water below a certain hardness level …ie soft is ok….
Given most people cannot measure / assess the hardness of their tap water deionised is the default choice..
