Default When to do coolant flush?

Looked at the service manual and I couldn't find anything on when to do a coolant flush on the mk6 TDI's. My car has 80,000kms on it now, so I have no clue when I should do it. This pink coolant does last a long time, I know, since my sisters 2006 BRM lasted on it's original coolant for 10 years and 300,000km and pH was fine, colour was still bright pink. But I don't wanna push it. Any advice?

If it looks good, I'd change it out at the timing belt interval.

How about never? You'll lose about half the coolant when you change the water pump, replace that and you'll be fine.

Timing belt change is also a good opportunity to replace the thermostat.
