Water pump AISIN or OEM Volkswagen

My impression was (recommended by many) this specific seller had everything OEM, water pump was the correct Aisin one.

RockAuto Aisin with the logos ground off. That’s when you know it’s the real deal.

Aisin only. It's the Oem.

Aisin TKF-005 has the 2 port pump and is otherwise identical to TKF-004 with the 3 port pump.

Waterpump. There's no way to visually inspect the WP without removing it.. Which would basically be a timing belt job. Pull the pump, I bet it's missing plastic.

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.

I’m on my 2nd water pump, and it is starting to leak. I still need a third water pump.

Water pump 1 failed during the original warranty. Water pump 2 failed just outside of the new extended warranty for them I think I was at like 101,000 miles. Water pump 3 has now failed. I think im at like 110,000. Im really sick of being stranded in the middle of the night after work and Im sick of paying over $$$ for this obvious problem that everyone knows is a problem with these cars. I cant replace water pumps on average every 3 years. This isnt normal. Im 40 years old and have had many, many cars and 2 work trucks. I have never has a water pump fail on any car ever other than this one.

My 35K miles 2021 GTI has been loosing coolant for a few months now.

When doing your own maintenance, a problem may arise in the event of a recall. My application under the water pump recall for my previous Tiguan (1st Gen - PQ) was denied even though it was replaced at a VW dealer because I did not show "convincing evidence" of having followed the scheduled coolant maintenance despite including my aftermarket receipts with miles and dates.
