Pros: still going strong
Vehicle:

Mileage: 246230 km
Has 137,000 miles on it original water pump. Still good to be used but don’t know when she’ll crap out. Very impressed that I lasted this long.
Pros: lasted very long
Vehicle:
BMW
Mileage: 220477 km
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.
Pros: long lasting, improved quality
Vehicle:
BMW
Mileage: 144841 km
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.
Pros: long lasting, worked great
Mileage: 160934 km
I replaced my water pump last weekend with a new pierburg pump from ecs tuning, everything went smoothly, no leaks, etc.
Pros: no leaks, went smoothly
Cons: overheat sign came up
It’s still baffles me how BMW can’t get a quality water pump on its vehicles.
Pros: quality water pump
Cons: quality water pump
Vehicle:
BMW
The water pump had a micro leak that would spray coolant on the air box. Never enough to make me want to go through the trouble of replacing it.
Cons: micro leak, coolant top-up
Vehicle:
BMW Z4
I changed the water pump on my e92 335i N54 2008 after it left me stranded 6 months ago. Approximately 2-3 months later, the car started running out of battery intermittently. At first it was once every month, then every 2 weeks, now it is every week. I've narrowed it down to the water pump staying on when I shut the car off, even when cold. The old water pump did this exact same thing before leaving me stranded. Both the old and new pumps are the all-aluminum Pierburg. I tried running the water pump test procedure with ISTA right after the pump kept running (after shutting down the car) and ISTA couldn't communicate with the pump. However, it did let me run other procedures, so that was not the problem. After letting the car sit down for 30 mins, ISTA was able to communicate with the pump and run the procedures. I have absolutely NO codes. My car does NOT have an IBS sensor, so that is not the problem. If I open a door, unlock the car, etc., the pump stops running. I'm about to purchase a new pump because I have troubleshot everything I could think of, but I can't imagine this brand new Pierburg pump is failing so prematurely (less than 5k kms).
Cons: premature failure, battery drain, pump stays on
