Generally the OEM plastic water pump only lasts as long as the timing belt interval. I wouldn't rule it out since the overflow water you might be seeing could just be water which is expanding or boiling as you increase the engine speed.

That is indeed a common failure item on the 2 liter turbo engine. One of my VWs went out @ 70k miles.
I had a coolant leak in august. They replaced my water pump under warranty. Brought my car in last week and guess what another freaking leak. They tried to charge me this time but are now fixing it under parts warranty.
Mine is a 2019 (abiet a GTI) and it's on its 3rd water pump
I have a 2013 GTI on the original water pump at 100k miles.
Someday, VAG will figure out how to make a water pump. *That day is not today.*
My waterpump just leaked.
I am now at about 55k and the water pump failed on it causing it to overheat. I learned that the 2015 gen 3 TDIs have a variable water pump that fails quite often causing overheating - just a matter of time.
I have a 2016 GTI. A little over 50,000 miles on it. No issues yet.
I'm rocking 110k miles on the original pump here on a 2015.
