Water pump Saleri or Pierburg

Pierburg ONLY for water pump, no other brand is good.

with water pumps on e9x’s it’s Pierburg or bust.

i replace with OE saleri pumps every so often and havent opted for a stewart pump.

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.

I had a Saleri pump. I changed it at 100,000 in 2013 and bearing was good at around 145,000 in 2021. I inspected it with a camera. It appeared to be leaking at the gasket.

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

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).

I got all aluminum Pierburg water pump to replace (working) VDO water pump. After putting everything back together, bleeding the system, I turned on the car, drove 40 miles with a couple on and off cycles and then shut it off for a couple of hours. I came back, started the car, I got the low coolant level warning, understandable, air escaped the system (I guess I didn't bleed it enough lol). Topped it off, drove 20 miles back home and then heating suddenly stopped working and coolant temp started rising. Went from 95 C to 100, then 105 and that's when I shut the car off, didn't want it to overheat. Ever since then, my pump works intermittently. I had a laptop set up next to me with INPA on today and drove close to the house to have the car ready for emissions (thank God!). After bleeding the system two more times yesterday it seemed like it was fine but while driving today, after maybe 20 minutes of driving, the pump stopped working and would not come back on again. It was like trying, the percentage rose to 30-35% and then back to zero immediately. Temperature went from 90 C to around 110 C rather quick obviously. Then out of nowhere, it started working again for a bit. Got close to the store I was going to, and it stopped working again. I was able to pull into the parking lot as it got to 120 C and got a yellow overheating warning. On my way back home from the store, the pump only started working again maybe 3 minutes from home, had to stop once and then turn off the car and keep rolling most of the way to not let it overheat. Also, there's no heating from the vents until I set it to 28 C but at the same time there's no movement from the pump in INPA.
