Water pump OEM Audi or Hepu

Ive reinstalled another new HEPU(made in germany) pump due to mileage. I don't think anything is wrong with the old one. When I cleaned the o-ring seal contact area on the block it was corroded right where it left an imprint.

If you're worried, replace both the water pump and thermostat. I would use a Mahle, Facet, or Wahler thermostat, and either a Hepu or Graf water pump.

I brought in my 2019 Audi A7 for an alternator recall. The car has 40k miles on it. While the car was in they found the water pump was leaking and said they replaced it under warranty along with the alternator.

Currently own a ‘15 S3 with 130k+ miles. Nothing really major to report for me outside of some known common issues with this generation (water pump, PODS, etc). Car has been great and honestly easy to maintain if you can DIY oil changes, brakes, and DSG fluid changes.

I remember on my S4 the water pump had a plastic impeller that was guaranteed to fail at some point. The aftermarket made one that was metal.

Water pump went out on two of mine around 100k.

About a month ago, I kept getting the “Engine Coolant Too Hot — Pull over and let engine idle” error. It would literally come on for a split second then disappear. On one occasion, I noticed that the coolant was low so I topped it off. The error went away for about a week, then came back. This time, though, it remained on and the thermostat actually crept up. I dropped that thing off at the dealer so fast… four days later they tell me that the water pump has started to fail and that one of the solenoids had started leaking coolant.

I got lucky and found out my VIN was part of the class action lawsuit for water pumps, got that replaced for free.

I am dealing with a similar issue right now on my CJAA which I changed the timing belt in April this year. Leaking from same spot. Hepu waterpump.

Just turned 51K miles and threw an engine light for the first time. Took it straight to the dealer, low boost fault code due to coolant migration from water pump failure. At 51K miles I’m out of warranty with a $7,500 repair bill.
