Water pump Gates or Pierburg

Update: it was the water pump. Got a new Gates water pump (screws and gasket included). Installed it, no sealant or anything. Works flawlessly. Not a drop anywhere.

I used the gates kit from rock auto including the gates water pump… Car seems to be driving fine for the past few thousand miles since install.

I usually end up with Gates or AC Delco.

Can't go wrong with a Gates pump.

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

We used to install gates pump and belt kits, but saw too many leaking water pumps well before they were due for another belt. Switched to aisin kits and haven't had a problem.

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

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.

Did a gates kit on mine. Water pump is leaking after 60k miles.

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).
