Water pump OEM Audi or Hepu

Graf and Hepu make 12v metal impeller pumps, direct fit no mods.

Any replacement whether it br Graf or Hepu are going to have a metal impeller and be an exact factory replacement. The wheel itself will be identical in shape and circulate the same volume of coolant.

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...

I ordered one from MJM Autohaus, a Hepu unit and its impeller is metal

My original plastic impeller pump failed at 145k miles. I replaced with with a metal impeller pump (Hepu IIRC).

2017 Q7 3.0T. Steadily using more oil over life of car. Now a quart every 350 miles. It doesnt have the power it used too. $1500 for a new water pump at 54,000 miles.

The only issue I’ve had with Audi over about 200k miles split between an 87 cs turbo Quattro and a 15 a5 cabrio is they each needed a water pump around 90k

Bought it in October, had it exactly 1 week, and the water pump blew. The dealer replaced it for free

I was topping up the coolant every month or so. Was advised I would need a new water pump, which I was expecting

Had to get water pump done on my A6 at 90000km / ~56000 miles. Was a couple years older than yours at the time, but still felt pretty low mileage to me.
