Water pump OEM BMW or Saleri

My water pump went out at 155k, 2006 BMW 325i auto

I’m at 180k, holding strong

My 330i started throwing codes around 135k. Replaced it for peace of mind and it turned out to be the original. I’ve heard somewhere that the water pump used in the 2006 325 and 330i is a bit different and lasts longer

Original water pump, lasted to 167k!

My experience with the N52 was great honestly. I owned a 2007 328i from 2007-2019 and put over 120,000 miles on it. The only engine issues it had were the water pump failing at 90,000, and the oil filter housing gasket leaking.

Water pump on the T4 EVWK went ok. But, it is a Saleri pump from Italy.

Well made, but they ain't cheap. Here's the diagrams for the N54 setup: http://www.realoem.com/bmw/par...fg=35 The water pump itself is over $500.

I replaced my water pump at about 205K miles. I had seen someone on e90post mentioning he saw fault codes before his pump failed. I decided I could wait if I kept a close eye. At about 205K miles was when I saw a fault code via ISTA/D. It mentioned something about "...water pump speed deviation..."

I bought a saleri water pump with plans to install it myself. When I realized the job would be a little harder than I expected I decided to take it to a shop to install. They just sent me a report saying that they installed the saleri and it “was not within the tolerances for the spec” and it began “leaking immediately”. There solution is to order me a graf water pump which they describe as a “reputable” brand which insinuates that I brought them a water pump worse than a graf which from my research doesn’t seem to be true. I’m a little frustrated as they are billing me $400 extra to buy and install the Graf when I thought the saleri one should’ve been fine.

After researching I decided upon a Saleri pump from World Impex since it has the resin impeller and is 1/4 the cost of OEM. Well, the first one arrived with one of the vanes broken off the impeller. Impex rma'd it, but the second one arrived in even worse shape with a big chunk broken off the impeller. I attribute it to poor packaging.
