Water pump AISIN or OEM Volkswagen

Used Aisin for my 2000lx.

I have a 2013 GTI on the original water pump at 100k miles.

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.

I have no issues. Mines a 2017 with 86k miles (used to do only highway for 4 years).

Mines at 85k, no probs yet.

My 2012 Tiguan SE 4Motion, 18k miles so far 1. Water pump high pitch noise when engine warm up, it happened at around 700 miles (pretty new), dealer said it is a flaw of that particular water pump, they ordered the part and replaced it.

My mk6 went through THREE water pumps. All covered under warranty because a class action lawsuit forced VW to extend the coverage period several years, but still a pain in the ass. What's frustrating is that VW kept replacing them with the same faulty pump instead of addressing the problem and redesigning it.

I have a MK6 and a MK7 and they both suffer the same crappy design. Making a water pump primarily out of plastic is just a bad idea. My MK6 is on at least it's third water pump at a little over 100k miles.

metal impellers definetely can eff up your setup. I had one on my 2.0 jetta. and it completely froze, and caused me to overheat, which killed my headgasket. The engine never fully recovered from that.
