Water pump OEM Audi or Saleri

I wasnt planning on changing mine either when i bought my Audi TT and it had 61k miles on it and was just going to change belt and then at 100k the pump+belt.. when i took the pump off to see if it was plastic impeller style the impeller wasnt even attached to the pump.. it was just free spinning on the shaft.. i to this day have no clue how the car never overheated before that day.. cause i drove the car 2600 miles in 9 days prior to doing the timing belt. ill dig up the link but i posted a link on here of a movie how i could flick the impeller and it spun like 6 revolutions on the shaft without the actual shaft moving...

the aux water pump is leaking you can do it without taking the intake manifold off thru the driver side rear if the engine shouldnt cost you more than 200 when your all done

I bought a saleri water pump with plans to install it myself. When I realized the job would be a little harder than I expected I decided to take it to a shop to install. They just sent me a report saying that they installed the saleri and it “was not within the tolerances for the spec” and it began “leaking immediately”. There solution is to order me a graf water pump which they describe as a “reputable” brand which insinuates that I brought them a water pump worse than a graf which from my research doesn’t seem to be true. I’m a little frustrated as they are billing me $400 extra to buy and install the Graf when I thought the saleri one should’ve been fine.

Waterpump and thermostat are common issue with Audi. I had a 2017 S3 and had it replaced around 65K miles, and now my 2019 S5 was replaced under warranty at approx 38/39k miles. The mechanic mentioned something along the lines, its made out of plastic.

My water pump and thermostat just went out on my ‘18 Allroad and was pleasantly surprised to find out that they were both under an extended warranty even though my car’s general warranty had expired last year.

My waterpump developed a crack 3 weeks ago and I started to leak coolant. Car had 20,000km on it. Had it all replaced under warranty. Was open about the mods on the car as well and dealership didn't give me any issues.

Waterpump failure at 26k factory installed (plastic impeller, bearing)

After researching I decided upon a Saleri pump from World Impex since it has the resin impeller and is 1/4 the cost of OEM. Well, the first one arrived with one of the vanes broken off the impeller. Impex rma'd it, but the second one arrived in even worse shape with a big chunk broken off the impeller. I attribute it to poor packaging.

Not true. The maintenance schedule for the belt is 105,000 miles. Many of the pumps with plastic impellers fail before that. The plastic composite seems to age and become brittle after 70k or 80k miles--some sooner and some later. But they do fail. This is what happens:
