Water pump AISIN or OEM Audi

Used Aisin for my 2000lx.

We used an Aisin water pump. We have had no problems with this water pump as of 11k miles on the engine rebuild now.

I had my timing belt done by not a Volvo specialist specifically, but a “European brand” mechanic. They used an Aisin pump / Gates belt kit and life is good.

There’s a really good kit that come with gates timing belt, tensioner, idler, Aisin water pump, Toyota cam and crank seals and a serpentine belt for $350 I used it and everything has worked perfectly

You should be fine with the Aisin. They were the OE manufacturer for a lot of makes.

I have a 2016 A6 2.0T w/52K on the clock now and it's been reliable thus far, although I did have to replace a water pump at 17K.

At 52k miles, it appears the water pump went out on our 2015 Audi A3 1.8 T FSI. It has been drinking coolant the last few months and leaving the garage smelling like anti-freeze... the coolant leak is visible beneath the airbox/battery area.

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)

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:
