Thanks guy, but what is that G12 number? Halfords search engine gave me G30 but on the bottle there's nothing like that data. With my previous cars it only said the colour of the coolant in the manual if I recall that right. CheersAs Sarge says G13 latest Audi coolant but it originally was filled with G12 as stated on the expansion tank. So G12, G12+ G12++ and G13 are all suitable. NOTHING ELSE.

Best to stick with the genuine G13 VW/Audi coolant which is not available pre diluted.
Wouldn't risk non genuine stuff.................a few pence extra for piece of mind every day.......Euro car parts have G12 and G13

Cheaper than amazon and to the same spec.
It may be made to the same spec but through experience of after market products and a life time in the motor trade there are just some things that I prefer to use to have security and piece of mind........................oil is a prime example, formulations can meet a spec for a period of time but when stressed and exposed to combustion byproducts it degrades very quickly. (I could invite a good friend in the US who works for Chevron in oil development and who also holds patents for products to give us a run down on this but I'm sure we don't want to spend weeks trying to understand ......LOL) the same can be found in antifreeze and for the sake of a few pence is it worth finding out when your cyl head has corroded away or the side effects of chemicals used caused internal silting of the block......Made to the same spec, so why wouldn't you use it. That is like saying you will only run a car on the exact same make and model of tyres that it left the factory with. Still your choice.
I seem to have opened a little can of worms!Best to stick with the genuine G13 VW/Audi coolant which is not available pre diluted.
Lowest acceptable dilution rate is 40% G13 with 60% de-mineralised (distilled or de-ionised are other names and all suitable for cooling systems)
50% is the best compromise and anything above 60% G13 with 40% water actually reduces the cooling system performance
