Water pump OEM Audi or Pierburg

I'd recommend looking at an upgraded Pierburg water pump. None of the plastic bits & will save you from replacing it again in a few years.

going strong doing water pump and new oil pan right now. Tensioners were done as a precaution at 195k.

Water pump started leaking so replaced it, the thermostat, and the pcv. Oil changes 4k-5k. Love the car.

Have installed many pierburg Full alum cast pumps as well with good results. The Pierburgs are made in china FYI

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.

I replaced my water pump last weekend with a new pierburg pump from ecs tuning, everything went smoothly, no leaks, etc.

I've had 2 of these die in less than 1 year. Junk!

2019 Audi Q8 water pump failed around 80k miles. After looking into it, I found out Audi originally used a 4-bolt water pump and pulley design on these engines. The problem with the 4-bolt setup is that it didn’t distribute load evenly. Over time this caused premature wear on the shaft and bearings, which led to leaks and pump failures much earlier than expected. Audi must have known it was an issue because they stopped producing the 4-bolt pump and redesigned it with a 6-bolt system that spreads the load better and holds up longer. This wasn’t just normal wear—it was a weak design from the start.

Honestly, personally I wouldn't get a Pierburg. Got one, the all aluminum one and it failed right away, first day of driving. It was hard to push in the plug as well. And they are made in China these days, cheaply made it seems.

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).
