Water pump OEM Audi or Pierburg

we always used Pierburg assemblies with Mahle gaskets/o-rings if needed.

The BMW original from pierburg last way longer than 60,000 miles, more like 90,000 miles. Plus, as time went on they made them better than before. Getter a new one today will last longer than the original one.

We routinely get cars with 120,000 miles on their first water pump too.

My car had a Pierburg on it for over 100k miles and 12 years. It still worked great before I replaced it out of caution.

I went with the all metal Pierberg pump for my E90, with an N54. The problem with the plastic is that it gets brittle due to thermo cycling, and that is s problem for all of the plastic parts in these engines (valve cover, radiator, expansion tank etc etc). I probably only have 10-15k km on this one so far, but no problems to report and some very long driving days.

I own a 2021 S5 with around 55k miles on it, bought it with around 50k miles on it. Only issue is that the water pump did fail and coolant migrated into the vacuum system which is a ridiculously common failure on these cars.

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.

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.

when my original pump went bad, i went to Peirburg so that the plastic housing wouldnt crack. Pump lasted about 20,000 miles, bought another one from fcp euro for the lifetime warranty but this one lasted 20 mins before i got those same codes and overheated.

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.
