i replace with OE saleri pumps every so often and havent opted for a stewart pump.
Owner reviews for water pump
Hepu pumps are the best.
I installed one on me 325i 12k miles ago, no issues so far, it was part of the FCP euro water pump kits
6 months and 4000km on mine. Only found out a while after Graf has a bad rep. But no problems with mine yet.
Carbon cleaning, water pump replacement, possibly turbo replacement, timing chain, and dsg service are large ones over 100k miles. Those are issues I've had with my a3 with the 2.0t with over 138k miles.
2019 atlas (built 11/18) it had the water pump dine around 60k, nothing else engine wise, just rolled 95k.
Have had bad luck with graf metal impeller pumps, multiple failures over 2 different cars.
I have no idea how there isn't a class action against VW for those shoddy waterpumps tho. Had to do it on my one and literally every VW owner I've spoken to has had it be a problem
My febi water pump broke it's impeller at 60k.
Aisin is of course the manufacturer of the defective one you are replacing. So there is that.
