Coolant Life and Testing

I've done a bit of research but without finding anything conclusive. A 100,000 mile / 10 year "life" for the Pink coolant seems to be a common theme as does the (almost coincidental) changing of the water pump and hence the coolant at the time of the cambelt change.

There were some generalised references to checking the state of the coolant at each service which makes me wonder if Skoda dealer "inspections"  include this? I suspect not. Has anybody ever had a note on Skoda maintenance invoice noting that the coolant quality had been checked? (The coolant level should have been checked of course.) There is certainly nothing listed under Skoda's set price "Maintenance" table that would otherwise suggest that coolant needs changing on a regular basis, unlike engine and DSG oil, etc which do appear on the table.
