No just filled with tap water to test it

but the car is off the road at the monent getting ready for next mot. so still can be changed to g12 nad distilled water

may a act stupid and ask whats the big deal with g12 antifreeze and distilled water

 

The system is not designed for other types of coolants. Why risk it? G12 is like 20 bucks a gallon and lasts for years.

As for distilled water, you want distilled because tap water's chemicals can cause pitting and corrosion inside the radiator.

because it's not stated as an error code or is not listed.
