Water pump GRAF or OEM Volkswagen

I have a 2015 R and my water pump failed in January, about 2 months before my warranty expired. It was covered by the dealer under the warranty so not sure what the cost was. Pump and thermostat were both replaced.

Water pump refinement Again, not looking for anything miraculous here, just making for a smoother flow.

Just had my water pump replaced about a month ago to resolve the issue during my 40k service — hoping it holds. Techs at local VW dealership took about two days to locate the issue and make sure it could hold pressure. I was covered under power train warranty

I have been running the Graf AL pump for about 10k so not long enough to give a full assessment, but the quality was awesome and very pleased with it.

In the end I just went with the genuine vw part from FCP. The original lasted 149k miles and I have never heard of an OEM pump leaking, just the earlier design impeller breaking apart. And I know that problem has been rectified through Vw. So as long as it holds together for at least 100k miles, I now have a lifetime warranty through FCP.

I purchase the all aluminum pump made by Graf from FCP euro, they have a lifetime warranty, free shipping and good prices. I removed the manifold to get to the water pump. I had a problem with the cheap thermostat that came with it. It caused my car to run hot.

I’m on #4, but luckily all were replaced under warranty. Most recent was in 2019 when supposedly they had finally found and fixed the issue (not sure what ended up being the cause)

One of them hadn’t even failed yet, and they replaced it under recall since a new revision had come out

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.
