Water pump GMB or OEM Volkswagen

Turned out to be the water pump

I've used GMB some 10+ years ago. They were made in Japan and came with a lifetime warranty.

water pump should be changed to metal impeller version at the time of timing belt change

Only main issues I saw were leaking vacuum pumps, valve cover gaskets, pcv leaks (whole valve cover assembly) and water pump sepage.

I had been hearing a hitch-pitched noise from my engine that almost sounded like a vacuum cleaner about 5-10 minutes after engine start up. Took the car into the dealer to find that it was a water pump failure (as I kind of knew from poking around here). It looks like this is a fairly common issue for 2012's unfortunately, but just a heads up for people as this didn't trigger a CEL or anything.

Had the first water pump replaced 02/13. The coolant warning light went on this week so I made an appointment with my dealer. 25k and on the 2nd replacement water pump.

I just had my secondary water pump replaced a month ago. Yesterday I found a huge puddle of coolant in my driveway. Off to the VW dealer again. This time it's the water pump.

I've a 2012 GTI with just over 9K miles on it that had a water pump leak on me yesterday. Took to dealer and got it back this afternoon. I live 2 miles from the dealer and drove home no problem. On the way to my parents 40th wedding anniversary dinner this evening no more than another 2 miles after I left home it had another major leak happen. The coolant reservoir had completely cracked and I had coolant all over my engine compartment.

went in for my 20k maintenance/service on my 2011 GTI, Waterpump was shot, replaced free of charge but leaves me worried...

My water pump just needed replacement as well. I didn't have any visible or audible signs besides the low coolant level alert. The dealer said that this has been a fairly common issue but there is still no recall.
