When did you last check your levels?
I looked at mine yesterday, it was just above the minimum, I was going to top up with some I had here, but noticed the MK7 uses G13 and I have G12, apparently you are not supposed to mix them.

So I'm not the only one.....hmm this is a concern really as my coolant has began to drop again since Jan!
G12, G12+ and G12++ are replaced by G13 since a couple of years ago. I have mixed them in e.g. our A4 and my former GTI 6 without problems. They are mixable.

Lots of liquids are 'mixable' but are they all compatible?
Anyone doing this - please make sure engine is cold before opening the cap....
